Timbren FRTT350F 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

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 FRTT350F

Ask A Question

I have the 6k system on my 08 F250 and want to go to the 10k system.....do they mount the same way? Could I use the mounting system on my truck now and change the stops/levelers with the 0k parts?

Asked January 26, 2018

Carl

Timbren kit FR250SDF and FRTT350F use different mounting brackets to attach the spring to the frame, so they are not interchangeable.

Do you sell rear kit for my truck? 2012 Ford F-350, dual rears,chassis cab w/flatbed, 6.2 gas. Vin # 1fdrf3g68ceb59238 It is my hot-shot rig. I use it to haul stuff for a living. I can haul(payload) up to 6000 lbs. now. Will your product allow me to haul more weight? If so how much more? What does that 10,000 lb. rating you have mean exactly? Thx for your help.

Asked January 24, 2013

Timbren Kit FRTT350F is the correct kit for a 2012 F-350 Cab and Chassis that is used to frequently haul heavy loads. The Timbren Kit is rated at 10,000 lbs. The rating is the capacity of how much weight the Timbren Springs can hold. It will not increase you hauling weight or GVWR by 10,000 lbs. because there are many factors that go into determining you GVWR, such as brakes, tires, etc. The Timbren Kit will prevent the rear end of your F-350 from sagging and help keep your truck level. It will distribute much of the weight onto the Timbren Spring giving you extra support in the rear of your truck. Timbren kits are very popular with heavy haulers and we have been selling them for years with positive feedback. If you have any additional questions, feel free to call us at 1-800-358-4751. We stock Timbren kits and they ship within 24 hours. Thank you!
