When installing Deaver leaf springs or just removing the factory block, you need to relocate the factory rubber bumpstop so that you don’t bottom out the shock before the suspension. Now with this spacer installed the bumpstop will contact the housing correctly and keep you from damaging the shocks.
We CNC machine these in-house from 6061 aluminum, then have them bead blasted, anodized and laser etched. We include the necessary metric hardware.
For serious off-roading we recommend our air bumpstop kit using FOX or King 2.5 bumpstops for increased bottoming control.
