This simple piece sits on top of your existing strut assembly to add a bit more boost to your front end. The spacer pieces is 3/8" which translates to roughly 9/16" of final lift boost at the tire.
Its a nice way to add some extra boost to your front end if the nose-down position is bothering you. Or perhaps if you have added a heavy front bumper system. Or even if your springs are tiring out a bit.
The kit is sold in pairs.
They do slip on top of your existing strut assembly so no dis-assembly of the strut is required. Makes them very doable for the shadetree mechanic. There is just enough threads on the top of your strut bolts to allow this piece to be used. Anything taller requires removal of the studs which means strut dis-assembly... a bit of a headache.
This is also an excellent add-on for our OME springs too for those wanting a bit more leveling boost on the front.
