FAQ:

Will this work on all Discovery II years?
Yes—fits 1999–2004 Discovery II (L318). It’s designed to replace the factory rear air suspension with coils.

Do I need to reprogram anything after the swap?
Many Rovers require the SLS warning to be cleared/disabled using a diagnostic tool after converting to coils.

What do the adjustable shocks do?
The 4-stage adjusters let you quickly tune damping for comfort on-road or firmer control off-road and when carrying extra weight.
