For the ultimate in ride quality, combine your U-bolt Flip Kit with All-Pro’s Timbren Bumpstop Kit. The Timbren Suspension Enhancement System utilizes high-grade rubber hollow bumpstops to enhance ride quality at the compression end of suspension travel. The open bellows design of the Timbren bumpstop allows for a progressive forced to be exerted on the vehicle’s axle, light at first then increasing in force as the bumpstop compresses. The result is a better ride overall, and smoother landings on jumps and hard hits. The Timbren bumpstops provide performance that can not be matched by solid urethane bumpstops, at a price much more reasonable than expensive hydraulic bumpstops. The complete Kit comes with a pair of Timbren bumpstops with mounting brackets and hardware, heavy duty u-bolts with nuts and washers, and heavy duty CAD-plated u-bolt plates that have been modified for use with the Timbren bumpstop kit.
