Timbren GMFK25D 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

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!

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.

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.

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.

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.

Customer Q&A - Timbren GMFK25D

Ask A Question

Are these factory height Our do they raise the front end

Asked October 7, 2014

josh

Timbren kit GMFK25D will help the front of your truck maintain factory height. They will provide extra support and prevent the front end from sagging. They will not provide lift above factory height but will prevent it from sagging down if you add a snow plow, grill guard, etc.

Will this product raise your front axle gawr to 6000 lbs.

Asked July 15, 2013

Bob

Timbren Suspension kit GMFK25D will provide extra support for the front of new model Silverado or Sierra 2500 and 3500 HD's. The front Timbren Suspension kit has a weight rating of 6,000 lbs. This is what the capacity of the springs are in the Timbren kit. The kit will not increase the GAWR of your truck. There are other factors that are involved in calculating the GAWR that the Timbren kit will not increase, so it does not change the rating. The kit will provide extra support to the front of your truck and prevent if from sagging when hooking a snow plow, etc.

Do you make taller front bump stops? example 2" front leveling kit for a 2016 gmc 2500hd duramax. I want the bump stops to work when i put my plow on.

Asked January 30, 2019

TIMOTHY

I spoke with Timbren on this kit being used with a 2" leveling kit. With the Rubber Aeons being so far inward a leveling kit does not have much of an impact on the performance of this kit. It actually may improve it due to the fact that when the plow is removed the Timbren may no longer contact the control arm and the ride will improve. When the plow is installed the Timbren will contact and offer support.
