  • Q:

    Will the use of this product eliminate the awful banging I hear when hitting road seams and bumps on my 2007 Ford E450 24foot class C motorhome. Remove the shocks provided no difference in ride, eliminating them as the source. I feel the suspension is too stiff for this shorter and lighter bodied motorhome. The ride height is still level and it appears that the rear leaf springs are not fatiqued.

      Without seeing your Ford E450 motorhome, it would be hard to determine for certain what is causing the banging. Typically it is the rubber bump stops. If you have a small gap between the bottom of your bump stops and your axle, hitting a bump will cause them to smack against the axle causing a banging sound / feeling. The Timbren kits replace that factory bump stops with taller springs with a higher capacity rating. These will eliminate the banging but will not create a softer ride than you have now.

      We have had customers in our shop with a stiff riding E450 and we put them in Bilstein comfort setting shocks 33-187563 and 33-186863 and they were very happy with the ride.

      Feel free to call us at 1-800-358-4751 with any questions.

Product Details

Timbren Kits - Overview

Timbren Suspension Enhancement Systems work in conjunction with the existing suspension, to improve your ride and to protect the vehicle against the effects of overloading.

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 suspension kits offer the following benefits:

  • Helps eliminate spring sag and improves stability
  • Maintenance and trouble free - No air lines
  • No special tools or skills are required to install your Timbren kit
  • Requires no alteration to your present suspension - Uses existing holes in frame
  • Each kit is complete with all the necessary parts & instructions for easy installation.
    Please note, your kit contents may vary depending on application.
  • Timbren products have added stability to trucks, vans and RVs for over 40 years
  • Used by municipal & state highway departments throughout the U.S.
  • Improves your vehicle's ride and protects against the effects of overloading
  • Lifetime guarantee

Typical Uses for Timbren Kits

Snow Removal Equipment: Whether you use a pickup to clear a small driveway or a class 8 highway truck with a wing blade, Timbren Industries has a suspension enhancement system designed to provide a safe and level ride for plowing snow in the toughest of environments. These high performance suspension kits are spec’d on most state, county and provincial transport equipment for snow plowing. Many snowplows are also equipped with very high center of gravity salt spreaders carrying heavy loads that induce sway. The rear Timbren Kit will improve roll stiffness and absorb road shock.

Towing trailers: Whether you are towing a horse trailer, RV or full size 54 foot highway trailer, a Timbren Overload Booster Kit installed on your tow vehicle will provide you with peace of mind because you’ll know that your suspension can handle the extra stress. The enjoyment of a safe, stable ride without the expected sag from the weight of the trailer makes the addition of the Timbren suspension enhancement system an easy decision to make.

Recreational: Remember the last time you were driving ‘white knuckled’ through the mountains, wondering if your RV and tow vehicle were going to make it through the next hairpin turn? Rest easy with the Timbren suspension enhancement system on your vehicle. Not only will this product improve roll stability and reduce sway on top heavy loads, it will also improve vehicle dynamics and high speed maneuverability without comprising ride quality. Timbren’s suspension enhancement system provides peace of mind for users of vans, pickups, SUV’s, Class A, B, C recreational vehicles.

Towing: Timbren excels in the wrecker industry with the use of the Timbren suspension enhancement system. From a ¾ ton truck with a sneaker unit, to a full size class 8 wrecker, Timbren’s muscle provides the capacity needed to haul anything. Our compact severe service package allows drivers to maintain a safe even ride without the front of the vehicle pointing to the sky. By shifting the weight to the front axle and maintaining a level ride, a Timbren Kit will keep you moving, and you will never again have to leave a potential tow at the side of the road!

Emergency Vehicles: Emergency vehicles often need an improvement in vehicle dynamics and high speed maneuverability without compromising ride quality. Timbren’s suspension enhancement system provides excellent stability while offering a smooth ride with any loading condition. Ambulances, fire trucks, and service vehicles all benefit from the extra safety and capacity provided by a set of Timbrens.

Agriculture: From hauling hay through a field, to high load off road applications, the Timbren suspension enhancement system will protect your suspension, and will improve the performance of your vehicle whether it’s a pickup, medium duty straight truck, or a full size class 8 truck. For leaf spring, torsion bar, air ride and other types of suspensions the suspension enhancement system provides stability, maintains ride height, and improves the vehicle dynamics for both on and off road applications. Timbren also provides custom applications for other agricultural equipment including bailers and sprayers.

Timbren Kits Solve the following Suspension Problems

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.

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.

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.

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.
