I don't have the RC BB, I have the RC 2.5" spacer lift, I chose this, because it's all STEEL and I already have Rubi springs
I bought seperate, RC9000xl shocks (adj), any time you get a deal on shocks/lift/springs--there's going to be a sacrafice in quality, either plastic/rubber/cheap shocks/poor quality springs
I'll stay with Hankook Dynapros, for tires,they're probably the best (BIG) tires I've used on different 4wd's
To do the lift yourself is not a HARD JOB, but it's dangerous and I didn't want to do it more than once,(I've done this job before) so I'm staying in the 33/34" tire range--NO 35'S !!!
I did not need any track bar adjustments or changes, because my axle shift (because of lift) is not noticible and the E-disco's noticed no change
As long as the steering wheel (drag link) is adjusted IMMEDIATELY, there is no ECM confusion
The sway bar links are OK, but
You must/should put in extended bumpstops Front/rear and MUST extend the rear brake lines, down several inch's--I did mine 3 inches and made 2" rear Ex bumpstops, the front are Daystar
