Timbren Kit

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.

Easy to Install

Timbren kits are simple to install and require no alteration to your present suspension. No special tools or skills are required to install a 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.

OEM Manufacturers specify Timbren

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.

Typical Uses for Timbren AEON Rubber Springs

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.

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.

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.

I installed a rear kit on my pickup truck and it's almost touching the axle. The installation instructions indicate that I need a 1"

Remove the spacer supplied in the assembly. If you have already done this, or if there is no spacer in the kit, then take the vehicle for a test drive. Often the suspension enhancement system is installed on vehicles with a partial load, or on vehicles with an older suspension. In these cases the rubber spring may be in contact with no adverse ride quality. If the ride quality is poor, give us a call at 1-800-358-4751, or contact Timbren Customer Service at 1-800-263-3113.

I installed a rear kit on my pickup truck and there is over 2 inches of gap between the rubber spring and the axle. Is this OK?

Ideally the rubber spring needs a gap of about 1 inch. In most cases, this can be done with the spacer included in the product. If you have already installed everything included, give us a call at 1-800-358-4751, and we'll assist you.

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

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.

I'm getting a rough ride when I'm unloaded. Can that be fixed?

Measure the gap between the rubber spring and the axle to see if there is enough clearance. (See question and answer 1 for further details and solutions).

The rubber spring is touching the axle all the time. Will that hurt the truck?

The point of contact on a loaded truck actually is a secondary point of contact. The entire weight of the vehicle and payload normally contacts the axle at the point under the leaf springs. By adding a secondary point of contact, just inside this point, we are reducing the stress of contact at the original point and are spreading out the load to 4 points of contact on the axle instead of 2. As well, the progressive spring rate provides a soft uptake of the load rather than the sudden stop of a solid bump stop, again providing a good ride with reduced stress.

I have a 1985 motor home that is sagging badly in the rear. Will your suspension enhancement system help?

The Timbren suspension enhancement system will certainly help, but it is designed to work in conjunction with a suspension that is in good condition. We recommend that the motor home be inspected by a suspension specialist to make sure the suspension is in good condition prior to installing a Timbren system. If you need more information, give us a call at 1-800-358-4751 - we are experts in service and repair of vehicle suspensions.

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

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.

What are the benefits of the Timbren SES system as compared to an air spring system?

Some of the advantages over the typical air systems are:

• The Timbren suspension system can be installed in about an hour (less shop time)
• The Suspension Enhancement System has a satisfaction guarantee
• The product is trouble free
• There are no airlines to leak, no maintenance required
• There is a Lifetime guarantee
• The product is about ½ the price of an air system
