Product Installation: Rear Timbren Kit

Timbren Kit Memorial Day has come and gone, that means summer has finally arrived. This is the time to get those campers, boats and trailers out of storage and back on the road. Unfortunately, this means added wear and tear on your pick-up truck’s suspension.

Have you been noticing that extra strain on your truck suspension lately? Are you bottoming out your leaf springs every time you pull your trailer? Is there a noticeable sway in your ride when you pull your boat? Does pulling that huge camper make you nervous around turns? If this is the case, your problems can be solved by adding a Timbren Suspension Enhancement System to your truck’s rear suspension.

Chevy Truck Timbren KitWe recently installed the Timbren GMRCK15S Rear Bump Stop in a 2002 GMC Sierra 4x4. The owner of this truck had been towing a 21 foot 5th wheel trailer and had noticed that his leaf springs were bottoming out. Concerned that the shock would damage his vehicle, he brought it to our truck suspension experts. Adding a Timbren kit to his vehicle’s suspension system was our answer.

Upon inspection of the Sierra, we found evidence of trouble already brewing. We noticed that his pre-existing bump stops were grossly inadequate for the load he was carrying. These bump stops were literally rotting off of their mounting brackets and took only a slight amount of pressure to snap them off completely.

Timbren kits are a popular addition to a truck’s suspension for several reasons. Adding a Timbren kit can go a long way to improve the quality of your vehicle’s ride by increasing the stability of your leaf springs. By decreasing the leaf springs’ range of movement, the Timbren helper spring cushions the impact on your suspension system, resulting in more road shock being absorbed by your suspension and less shock absorbed by you. Further, by replacing the pre-existing OEM bump stop, the Timbren kit protects your vehicle from the damaging effects of overloading. This protection increases the life of your vehicle and its suspension system.

The GMRCK15S fits 1999 – 2011 GMC Sierra 1500 and Chevrolet Silverado 1500, two wheel and four wheel vehicles. This kit will fit regular or 3 door models but it will not fit XFE models.
