These bumpstops packers or "spacers" are made by Eibach. They install on the shock shaft to effectively make your bumpstop taller so that you hit the bumpstop sooner when your suspension compresses. This is a fine tuning tool to limit shock travel in cases where you have more travel than you want, i.e. when the tire is hitting something inside the fender under hard compression.
This clip style packer has a cutout on one end so it can be installed on the shock shaft without having to disassemble the shock and spring - just reach your fingers through the gap in the spring and clip the packer on to the shaft.
Intended only for 5/8" diameter shock shafts, which fits KONI shocks. If you have a different brand of shock, these are not for you as they may not hold on to the shaft properly and might slide off.
Thickness: 1/4" per packer
Sold as a set of 4 packers.
We recommend installing packers below the bumpstop on the shaft.
