On a JK running AEV's 4.5in DualSport suspension, the rear bump stops set how far the axle can travel before it bottoms out, and worn or missing pieces let it hit harder than it should.
This service kit replaces the rear bump stops and spacers from that system. It includes two rear bump stops made for the 4.5in suspension and two round spacers measuring 3.0in in diameter and 3.0in tall.
Swap them in at the rear and the suspension stops where it was designed to.
