Bought these shocks for a Bilstein 5100 front. They are set for an additional 2 inches of travel. These shock absorbers are designed for rear passengers and do not provide lift. You will need an extra sash or block to elevate the back. However, these shocks are designed for a 2-inch rear stroke. Anything more than this requires a longer shock than this. To clarify, the front shock absorbers on the Bilstein 5100 are height adjustable, but the rear shock absorbers are not. and I left the standard Tacoma coils in front. The system looks good and works well.
