Pulling a trailer with the right suspension system for your application can make a considerable difference in ride quality and your overall user experience. Diamond C offers multiple premium suspension systems alongside our LIPPERT TRAILER AXLES to give you peace of mind while hauling and ensure your trailer lasts longer with less overall maintenance needed.
Picking which type of suspension system to include with your trailer is a very important decision, and varies based on which type of trailer you require for the job and what you are planning to haul. The correct trailer suspension gives you a smoother ride and protects your trailer and cargo by absorbing shock from bumps and dips on the road road.
We offer 4 quality types of trailer suspension:
- Leaf Spring Suspension
- Torsion Suspension
- Heavy Duty Adjustable Suspension
- Air Ride Suspension
Keep reading to learn more about Diamond C’s trailer suspensions and which one is right for you.
Leaf Spring Suspension
Leaf spring suspension arguably the most common and cost effective type of trailer suspension.
This suspension design is made up of a series of curved springs (leaves) that are stacked and attached to the underside of the trailer’s axle using hangers and U-bolts. The leaf springs in this suspension system function as shock absorbers – they flex and release when you hit bumps and rougher roads, which provides you with a smoother ride.
Tandem and triple axle trailers feature an equalizer, which sits in-between the axles and links the springs together. These equalizers float to help to transfer energy from one axle to another, especially while going over bumps to help soften the impact.
Leaf Spring Suspension Highlights:
- More budget friendly to purchase than other suspension systems
- Tried and true classic technology
- 6 Year LIPPERT Warranty
We offer a few different varieties depending on which axles the trailer has:
3.5K Axles: 4-Leaf
5.2K & 6K Axles: 5-Leaf Slipper
7K & 8K Axles 6-Leaf Slipper
Torsion suspension provides many benefits in overall design and function than a traditional spring suspension. The unique design of the Torsion axles includes a rubber torsion arm system that is self-contained within the axle tube, which then directly attaches to the trailer frame. The result is a far smoother ride, with less overall wear and tear on your trailer over the years.
The Torsion system uses a heat-treated solid steel inner bar that is surrounded by 4 flexible rubber cords. The wheel hub spindle is attached directly the the Torsion arm, which in turn is connected to the rubber-encased Torsion bar. As your trailer encounters bumps in the road, the up and down movement of the wheels causes the inner Torsion bar to twist back and forth. This rotating movement is simultaneously dampened and cushioned by the surrounding rubber cords, which provides superior shock absorption and gives you an ultra-smooth ride.
Torsion Suspension Highlights:
- The rubber cushioning from the 4 flexible cords eliminates all metal-to-metal contact and provides superior shock absorption
- Durable heat-treated solid steel inner rotating Torsion bar
- Independent wheel suspension allows each wheel to move separately from the others as needed
- Quieter ride than spring suspension
- Less overall maintenance and repairs required due to one-piece design
- 11 Year LIPPERT Warranty
Heavy Duty Adjustable Suspension
The Hutch Series 9700 heavy duty adjustable suspension system takes the traditional leaf spring suspension design a step further by adding several key features:
- Easily adjustable torque arm screws
- A maintenance free fastening system
- “Million Mile Rocker Bushing” – eliminates bushing fatigue and failure
All our 16K axle equipped trailers come standard with this heavy duty adjustable suspension, including our flagship gooseneck model FMAX216, heavy duty pintle hitch model PX216, step deck model SDX216, and our dual tandem gooseneck dump model WDT (with 30K GVWR package selected).
Air Ride Suspension
For a smoother, quieter ride, extended trailer life, & higher rates per mile, BUILD YOUR TRAILER with our top-of-the-line Air Ride trailer suspension upgrade from Ridewell.
Air Ride Suspension utilizes airbags on each tire made from a durable polyurethane and rubber material. Dual compressors pump air into each flexible bag, enabling them to absorb bumps and vibrations much more efficiently than on a traditional spring suspension system. While spring suspensions tend to compress and release the energy from bumps into your trailer frame and cargo, Air Ride suspension absorbs the energy under the frame before it even reaches your trailer body.
We are proud to offer this premium suspension system on all our GOOSENECK, PINTLE, and STEP DECK trailers as an available add-on. Air Ride suspension is a very popular option for HOT SHOT trailer owners who regularly haul uneven loads across long distances.
Benefits of Air Ride Suspension:
- Ride Quality & Cargo Protection: Smoother, quieter ride & reduced push-pull lessens fatigue of the driver & protects cargo being hauled.
- Reduces Wear & Tear: Less trailer bouncing extends the life of your trailer.
- Warranty: Ridewell offers warranty against any manufacturing defects, giving your customers confidence on the road.
- Front Lift Axle: This unique included feature saves tire wear & fuel consumption on empty hauls.
- More per mile: Air Ride allows your customer to net higher rates per mile hauling loads not allowed with standard suspension.
The Air Ride Package includes dual compressors, one 10V 5amp charger, and dual Group 27 continental BATTERIES.

*NOTE: This article references some of our now discontinued utility trailers. We discontinued our utility trailer lineup in 2021 to focus on what makes Diamond C Trailers truly unique – our heavier duty flatbed gooseneck, equipment, and dump models. You may still see some of our utility models from this article on dealer lots while we transition away from producing them.
Diamond C offers a variety of customizable fender choices for your trailer – from smooth to diamond plate to removable. Some options are for looks, and some are for added functionality and protection. Keep scrolling to learn all about our fender choices for your trailer.
16 ga Smooth Fender
Our most basic fender, found on our standard GSA general duty utility trailer.
16 ga Smooth Fender with Gravel Guard
On tandem axle trailers this fender has a teardrop in the middle for added coverage.
CAR HAULERS equipped with our “Pro Package” feature an aluminum gravel guard for a flashier look when hauling your show car.
14 ga Diamond Plate Fenders
3/16″ Super Heavy Duty Diamond Plate Fenders
Our 3/16″ Super Heavy Duty Diamond Plate fender option is a must for contractors and work crews whose environment requires equipment outfitted with the toughest features known to man. Pairs great with our HD 215 TIRE UPGRADE. Popular on heavier duty models like the TUT and EDU utility trailers, MVC Multi-Vehicle Carrier, flatbed equipments including LPX and HDT, and our medium and heavy duty dump models (GDT, MDT, LPD, and LPT).
3/16″ Heavy Duty Fenders Video
Drive-Over fenders are especially handy when loading wide equipment. Found as an upgrade on all CAR HAULERS and Equipment Trailer models LPX and HDT. These pair great with FRAME EXTENSIONS for those extra-wide loads.
In certain cases, we’ve found that some trailer users prefer the option to have removable fenders depending on what cargo or equipment they are hauling. Dealers who ship large quantities of trailers greatly benefit from this as it means they can stack more trailers on each load.
Most of our flatbed models (UVT Utility, all CAR HAULERS, and LPX and HDT Equipment trailer models) feature bolt-on fenders as standard, so they can easily be removed in a few steps by undoing 4 bolts.
Black Painted Fenders
Have a non-standard COLOR trailer with bolt-on fenders and want to stand out? Add black painted fenders for a cool 2 tone look.

Do you know trailer brakes? Diamond C offers 3 types: Electric Drum, Electric Over Hydraulic Drum, and Electric Over Hydraulic Disc brakes.
Below are some helpful tips for choosing the right brakes for your trailer.
Electric Drum Brakes
Electric drum brakes are the utility and flatbed trailer industry standard for trailer braking systems. Electric drum brakes are controlled by an in-cab controller that comes standard on many of today’s trucks and SUVs. Electric drum brakes are well suited for most general use applications – trailers that are used moderately within their capacity and towed with some regularity. If you plan to use your trailer aggressively in relation to its PAYLOAD CAPACITY and plan to tow it on a more regular basis, then keep scrolling to see our electric over hydraulic brake options below.BREAK-IN PERIOD MANUAL
How to Burnish Your Trailer Brakes
Electric Drum Brakes require a proper BREAK-IN PERIOD to achieve full performance. Watch below for a step by step guide from Lippert Axles on proper burnishing procedure.
Electric Over Hydraulic Drum Brakes
Electric over hydraulic drum brakes are similar in that they are controlled by the same in-cab controller as standard electric drum brakes. They also share the same actual drum braking components. Where they differ is that instead of electromagnetic force being utilized to help slow the trailer, the electric pulse from the to tow vehicle activates a small hydraulic pump that sends fluid into the drum to forcefully apply braking pressure.
Electric Over Hydraulic Disc Brakes
Electric over hydraulic disc brakes are similar to both previous brake types in that they are operated by an in-cab controller. However, disc brakes are what avid heavy duty trailers users would describe as “the ultimate” when it comes to trailer braking systems. They use the same hydraulic force we mentioned in electric over hydraulic drum Brakes for better braking pressure, but where they differ is the use of disc (rotor) / caliper braking components in lieu of the drums. Disc brakes provide increased stopping power over drums. In addition, disc brakes are more cost effective when it comes to upkeep and preventative maintenance over time. With disc brakes you are able to replace individual brake pads, versus replacing the more costly full drum braking assembly.
If you are a gooseneck HOT SHOT trailer user who puts in a lot of miles over the years, we highly recommend hydraulic disc brakes.
Benefits of Hydraulic Disc Brakes:
- Last longer
- Stop faster
- Cheaper to maintain for high mileage trailers
16K Disk Brakes
In early 2021 we announced the 16K Electric over Hydraulic Disc Brake option. This industry-first option has been a long time coming, and is the result of a 2 year collaborative journey between Diamond C and LIPPERT. These 16K Disc Brakes are now available on all FMAX216, SDX216, & PX216 models.

Constructed with 3/16″ Diamond Plate, this lid also doubles as bonus deck space.
HD V-Tongue Lid Video
14″ x 14″ x 42″ Underslung Box
A popular add-on for our heavy duty deck-over models DEC and DET for handy below-deck storage that’s convenient to access, but also out of the way of the equipment your are hauling. Add one on each side of your trailer if you want!
Lockable Steel Tongue Box
Model DEC comes standard with our Chain Tray in Tongue storage.
Add a Chain Tray Lid for extra convenience and security.
Full Width Diamond Plate Neck Box
Diamond C utilizes a custom Powder Coat paint process called the DM COATING SYSTEM. It allows us to offer trailer finishes that are exceptionally durable and beautiful.
We offer 8 standard colors across all models, as well as 4 special colors. Custom colors can be applied to your trailer upon request.

Top Rails & Side Uprights
The Diamond C lineup of DUMP TRAILERS boasts 1.5x – 2x wider than industry standard top rails and unparalleled side upright supports. This dump side design allows your trailer to take more abuse and not become deformed over time from loading over the side of the trailer with a bucket, or from the added stress over years of hauling rocks and gravel inside the body.
With added thickness comes added power and strength for your toughest loads!
14K – 24K Models:
6K – 10K Models:
Overlapped Central Seam
All our dump trailers also feature a central seam overlapped floor design. This makes for a much tougher joint where the floor plate meets, but keeps the seam out of the corners. This design prevents a habitat forming for moisture to cling to which prevents premature corrosion. We overlap the seam by at least 2 inches on all our models, which produces a much more durable dump body which will last you for years to come.
Dump Body Thickness
For those who demand maximum toughness and the most durable option possible for the job, check out our premium 7 GA DUMP BODY UPGRADE package.
Why do we use Telescopic Cylinders in our Dump Trailers?
Telescoping Cylinder Technology is changing the way we approach building and designing our DUMP TRAILERS. The direct push design of the cylinder allows for maximum dumping leverage and puts far less stress on the main frame of the trailer than a traditional scissor lift hoist does. It’s much like what’s been used for decades on semi-end dump trailers and heavy duty dump trucks. The front-mounted telescoping cylinder position provides greater lifting power than a traditional scissor lift hoist, and also handles imbalanced loads significantly better.
Our heavy duty Telescopic Cylinder is a 3 stage cylinder that uses a KTI brand power-up, gravity-down system to help conserve energy. We also offer an optional Wireless Remote for additional convenience.
What are the benefits of Telescopic Cylinders?
Our Telescopic Cylinder boasts many benefits over the more traditional scissor-lift and dual cylinder setups:
- More front of body dumping leverage
- Handles imperfectly balanced loads more efficiently
- Less stress on overall frame of the trailer
- Ease of system maintenance due to front mount location
What models is this offered on?
This efficient, tried and true technology is found on most of our DUMP TRAILER lineup, including our 3 smaller models: GST, GDT, and MDT, and also on our flagship heavy duty low profile LPT dump trailer (as well as being an available option on model dual tandem gooseneck WDT).
