hey jon thanks for posting. i got a great deal on the roush trak pak suspension a little over a year ago when they were being phased out. no real info on them just know they are made by kw with roush specs, supposed to be between kw's variant 1-v2 version, meaning that they offer ride height adjustment ala v1 and dampining adjustment ala v2. theyve just sat while i was waiting on mine to give out so im wondering if they are still good or if they leak pressure etc. over time? im looking at anytime after next week when school is done thanks
