For the ultimate in ride quality, combine your U-bolt Flip Kit with All-Pro?s Timbren Bump Stop Kit. The Timbren Suspension Enhancement System utilizes high-grade hollow rubber bump stops to enhance ride quality at the compression end of suspension travel. The open bellows design of the Timbren bump stop allows for a progressive force to be exerted on the vehicle?s axle – light at first then increasing in force as the bump stop compresses. The result is a better ride overall and smoother landings on jumps and hard hits. The Timbren bump stops provide performance that can not be matched by solid urethane bump stops and at a price that is much more reasonable than expensive hydraulic bump stops.

The complete kit includes a pair of Timbren bump stops with mounting brackets and hardware, heavy duty u-bolts with nuts and washers, and heavy duty u-bolt plates that have been modified for use with the Timbren Bump Stop Kit.
Important Notes:

  • Plates are shipped uncoated. We recommend painting them before installation.
  • Tighten bolts in X pattern until snug and torque U-bolt Nuts to 93 ft lbs and re-check torque specs after 100 miles of normal driving.
