For those who truly use their 2nd gen trucks offroad and are looking for the highest quality bumpstop setup available, we are now offering our bumpstop kit separately from the Extreme suspension packages.  Air bumps are used on trucks that need heavy duty bumpstops to prevent bottoming out your suspension, when a polyurethane bumpstop won't work for repeated hits.  Air bumps are commonly used on trucks that race in the desert or trucks that are jumped, or otherwise beat on hard enough where the suspension bottoms out regularly.  These bumps will contact your axle with 4" or less or suspension compression left, and help protect your expensive shocks and springs from damaging hits.  Anybody who needs air bumps already knows what they are, but up until now your only option was to do the fabrication work yourself.  This is the first and only pre-fabbed air bump kit in the world for 2nd gen trucks. 

This air bump kit is totally bolt-on if you want it to be, or you can weld the brackets to the axle for a cleaner install.  We utilize Fox 2.0 air bumps, which are a rebuildable, tunable, high quality nitrogen and oil-filled mini shock that is velocity-sensitive, with a slow rebound so that you don't have multiple hits on the bumpstops in quick succession.  These are often called hydro bumps, which is short for hydro-pneumatic, aka fluid and air.  Whatever you call them, these Fox bumpstops are extremely high quality with a large 1-1/4" shaft and a zinc finish so they look new for a long time.  The Fox bumps bolt into bump cans that are machined from DOM tubing, which are then welded to our CNC-cut frame brackets.  The frame brackets are made from 1/4" HRPO and bolt to the frame using the same holes as our air bag system, for an easy install and a modular setup that allows you to run both products together or separately without any issues.  Once the frame brackets are bolted in place, you simply weld or bolt the axle bump pads in place and you are ready to fine tune your suspension.
To fine tune the suspension, you will want to have the air bumps fully collapsed when the shocks still have at least 1/2" of shaft showing.  Then you can adjust the air bump pressure to your liking, and revalve the bumps if needed to work with your particular spring and shock package.  If you have our shackle flip and stock leaf packs, or our progressive shackle flip with Deaver springs, you won't have to do much more than bolt this system on and enjoy it.  We still recommend cycling your suspension to make sure the bumps engage when you want them to, and that they bottom out before your shocks do.  You can use air bump stop shaft spacers if needed to limit the travel of the bump shaft.  Contact us if you need more information on these spacers once you have begun the install process.
