  • JKS Front Adjustable BumpStop Spacer

While simple in appearance, bump stops are actually variable-rate springs that function as limiting devices for suspension compression. They are compressed between the chassis and axle under heavy impacts, effectively increasing the suspension spring rate and preventing expensive damage to the engine, fuel tank and chassis. Unfortunately, very few suspension kits address bump stops correctly as it simply isn't possible to suit every application with fixed-length designs due to individual vehicle variances.

Adjustable BumpStop Features

  • Variable height landing pad spacer system ensures correct bump stop clearance for virtually any lift and tire combination
  • Three interlocking and interchangeable spacer sizes can be stacked or used individually to provide six possible lengths - 0.75/1.25/2.00/2.75/3.25/4.00 in.
  • Allows proper setup of bump stops to prevent suspension from bottoming out
  • Easily compensates for vehicle changes, spring settling and sagging
  • Conveniently allows changes to bump stop clearance without removing coils from vehicle
  • Practical upgrade for inferior bump stop extensions and fixed-length designs
  • Also fits Wrangler JK right hand drive models
