Description
Dobinsons race ready hydro bump stops combine an off-road racing inspired triple seal design, a 3mm thick EDP coated steel body and includes interchangeable Rubber or Nylon rod ends to provide smooth, quiet, improved bottom out control during the harshest impacts with the ultimate in quality and longevity. The fully rebuildable and tunable shimmed CNC piston design allows a smooth initial impact with a progressive, velocity-sensitive increase in compression resistance to absorb impacts at the limits of suspension travel, whilst providing rebound damping to slow the bump stop rebound speed and reduce bucking and uncontrolled rebound associated with regular bump stops. Tunable Shim Stacks, Oil Levels and Nitrogen Gas pressures offer unlimited tuning combinations for your 4×4 or Off-road Race Rig to get the very best performance out of your suspension.
