There’s a quiet revolution happening right now in trailer suspensions. Timbren Industries has recently introduced some of the most original ideas, providing the industry with a series of trailer suspensions that are nothing short of genius!
Each proprietary design focuses on quiet and smooth – not to mention strong and durable. In fact, Timbren’s attention to detail ensures you get a quality product every time or your money back.
All of their steel components are laser cut and painted with a durable, long-lasting powder coat finish. The rubber springs and bushings are vulcanized with care to meet and exceed industry standards.
Furthermore, Timbren suspensions come pre-assembled, offering you ease of installation.
Axle-Less Trailer Suspension
This award-winning* product turns the traditional idea of trailer suspensions on its head. The most exciting feature about the Axle-Less suspension is the fact that it requires no axle! *Best Off-Road Product of the Year at SEMA in 2011
Think about the possibilities. Imagine the freedom to go anywhere without the usual restrictions of an axle. Experience a smooth, quiet ride made possible with Timbren’s rubber spring technology.
The Axle-Less trailer suspension has some unique features:
- Maximum Ground Clearance
- Progressive Jounce Spring
- Rebound Spring – giving you a smooth ride even when your trailer is empty
- Easy Bolt-On Installation
- Urethane Bushings For Quiet Operation
Bushings
We use premium urethane bushings in the design of the Axle-Less suspension. Small grooves have been machined into each bushing allowing grease to lubricate the pivot point. This provides added quietness to the suspension.
Rebound Spring
This spring plays an important role in the operation of the suspension. It creates constant tension on the jounce spring when the trailer is empty. This means that, full or empty, the trailer will always have a smooth ride and will never bounce around like a conventional trailer suspension.
Anything But Ordinary
Ordinary solutions solve ordinary problems. But when the problem is anything-but-ordinary, an extraordinary solution is required. Watch how the extraordinary Axle-Less suspension can solve off-road problems…
Off-Road & Overland
Maintain the same ground clearance on your trailer as you have on your tow vehicle, and stop worrying about axle hang-ups! The Axle-Less HD editions are designed to take the abuse seen on any off-road or overland expedition. Thicker steel is used for added strength and a softer Aeon® spring for more suspension travel.
Work Trailers
Whether you use your trailer to haul firewood or run a landscaping business, the Axle-Less trailer suspension will make the job a lot easier. Choosing a 4” drop spindle would allow you to keep the bed closer to the ground, making loading and unloading effortless.
Boat Trailers
The Axle-Less design allows for a lower center of gravity on boat trailers. This unique characteristic paves the way for improved handling at high speeds.
“The Axle-Less system is one of the most popular options we offer with our off-road camping trailers. The robust construction and flexible configurations allow us to dial in the setup to exactly the type of terrain our trailers are built to explore” - Matt Broadbent, Kakadu Camping
Silent Ride Trailer Suspension
Quiet and smooth. These two words describe the Silent Ride trailer suspension. Any clanking and banging sounds are silenced. Rough and uneven towing quickly evaporates. Its rugged design has been tested in both Canada’s harsh climate and the rough terrain of the Australian outback.
The Silent Ride trailer suspension has been engineered to meet a new set of standards. Here are some of its unique features:
- Fully Equalizing Tandem Suspension
- Exceptional Ride Quality
- Easy Bolt-On Installation
- Maintenance Free
- Durable Powder Coat Finish
- Steel Hanger & Pivot Point
The walking beam design is a critical element, allowing the suspension arms to freely articulate around a pivot point, ensuring that the Silent Ride tandem suspension maintains full equalization.
Bushings
Bonded rubber bushings are press-fitted, allowing the outside of the bushing to be fully engaged in the control arm. The result is an extremely durable, long-lasting bushing.
Rebound Spring
This spring acts as a shock absorber creating constant tension on the jounce spring. This means that loaded or empty the trailer will never bounce around. You are guaranteed a safe, smooth ride at all times.
Walking Beam Design
The Tandem Silent Ride trailer suspension is unparalleled. Its unique design – a walking beam around a single pivot point – creates the most dynamic equalizing trailer suspension on the market.
Strong. Durable. Equalized.
The rugged design of the Silent Ride trailer suspension delivers superior ride quality. ‘Equalized’ means an equal amount of load rests on each tire all the time. In other words, all four tires are on the ground at all times.
Axle Seats
Whether you are installing it on a new trailer or as a retrofit, bolt-on axle seats make it simple to accommodate a variety of sizes for both square and round axle tubes.
“I went to my cottage with the trailer, very smooth and quiet ride. No leaf spring broke - I usually break 1 or 2 springs every trip and I drive very slow. With this suspension we did 40 - 60km/h and we could have gone faster but I don't want to break my truck” - Guy Pelletier, Gatineau, QC
“I have just purchased the Silent Ride suspension for my boat trailer. The change is amazing: more smoothness, quietness, and control. The trailer pulls evenly with no swaying or jerking. As a result, I feel much safer on the road” - Jack Hannah, Ajax, ON
Dakota Air Trailer Suspension
Originally designed as a premium suspension for horse trailers, the Dakota Air system has evolved over the years. Its ultra-smooth ride is perfect for trailers carrying fragile cargo such as horses and electronic equipment. The durability of its material and design matches the more extreme demands of a construction trailer.
The Dakota Air suspension has some unique features to benefit your trailer:
- Built-in Shock Absorber to Ensure Smooth Ride
- Maintains Constant Ride Height, Loaded or Empty
- Heavy Duty Leaf Spring Trailing Arm For Articulation
- Maintenance-Free Design
Air Spring
A single-convoluted low-frequency air spring provides a larger surface area to accommodate bigger loads. These are high-grade springs with a factory-installed internal rubber bump stop.
Shock Absorber
Timbren uses shock absorbers exclusive to the Dakota Air suspension. Rubber bushings inside these shocks minimize wear and tear. Each shock is capable of handling a minimum of 8,000 lbs. of tension to prevent over-extension of air springs.
The combination of air spring, shock absorber and leaf spring help create a total suspension package ranging from 7,000 – 10,000 lb. capacities.
Leaf Springs
Each Dakota Air suspension is equipped with a heavy-duty leaf spring for added stability and strength. This metal spring allows for a more compact design that is lightweight and strong. Easy bolt-on design requires no welding.
Air Supply & Control Kit
The most complete easy-to-install air system in the industry. Comes factory wired and pre-assembled. The control panel uses stainless steel, lighted gauge and a manual fill point.
