Timbren Overload Booster Kits

Hollow Timbren rubber springs are mounted between the truck frame and the axle. They do not take the place of the existing leaf spring, but work in conjunction with it, acting as a bump stop, to improve the ride of your truck and to protect springs against overloading.

Timbren Ride Control products enhance a vehicle's empty ride quality, while providing protection against overloading, road shock, bottoming out, sway and broken springs. Timbren Front axle kits prevent front end nose diving. Together, these features provide a smooth, level ride, even with heavy loads.

Timbren kits are simple to install and require no alteration to your present suspension.

No special tools or skills are required to install your Timbren kit. Just follow the easy to understand Timbren Installation instructions. Within a short period of time, you will experience enhanced handling and increased stability (both front and rear applications) on your vehicle.

Many manufacturers, including Bombardier, Mack and Kenworth, directly utilize Timbren kits in their commercial products. Many other fleets, modifiers and converters install the Timbren load boosters as a supplementary suspension for their vehicles.

Timbrens are commonly used for the following applications:

  • Pickup Trucks
  • Snow Plows
  • Vans and SUVs
  • RVs and Motorhomes
  • Landscaping Trucks
  • Vehicles Used for Towing and Trailering
  • Emergency Vehicles

Timbren Kits Solve the Following Suspension Problems


Timbrens Reduce trailer sway
Trailer Sway
Eliminate wallowing along the highway, drifting in crosswinds or when passing heavy trucks. For more driver and passenger comfort, Timbren suspension enhancement systems sense vehicle body movement and automatically increase roll stability.

Timbren Kits Eliminate suspension sag
Suspension Sag
Heavy loads cause the front or rear suspension to deflect lower than desired. Powerful, durable hollow rubber cushions help carry the heaviest loads easily. Road shock is absorbed, reducing wear and tear on suspensions. The Timbren load booster acts as bump stop, to eliminate bottoming out on bumps.

Suspension Kits improve vehicle weight distribution
Body Roll
If your vehicle leans on corners or curves, progressive rate Timbren suspension kits can improve weight distribution to all 4 corners of the vehicle. This helps keep the vehicle level, improves steering and reduces brake and tire wear.

Timbrens help bumpy rides
Rough Ride
You feel every bump in the road and every expansion joint. Rubber bump stops in each Timbren kit are designed to soak up road shock and bumps. The result is a smooth stable rubber cushion ride.

Timbren Kit Q&A
Q. The capacity of the kit seems awfully high. I don't think I need that much! What do you recommend?

A. The real question you seem to be asking is "Will this give me a rough ride?" Timbren rubber springs provide superb ride quality both empty and loaded. No matter how small or big the load, the Aeon rubber spring will adjust to provide a smooth and safe ride.

Q. Can I haul more weight on my truck if I install your suspension enhancement system?

A. You cannot exceed the manufacturer's axle rating or GVW rating of the vehicle. The Timbren suspension enhancement system will greatly enhance the performance of a heavily loaded vehicle. You can expect the vehicle to have reduced sag, and improved roll stability.
