Unfortunately our 2008 adjustable lower link design never made it passed our practice field. The mechanical implementation on that design (PVC and gas shocks) had a serious transition phase that caused our programmers fits. We ended up re-designing the lower arm and replacing it with a solid link as soon as it came out of the crate Thursday morning @ FLR.
Raptor's adjustable arm is much more elegant and functional than that HOT '08 adjustable arm ever dreamed of being.
