Blacknight, did you ever change the speedo for correction for your different tire size?
I've got an 02 XL7 and planned to do a 3/4-1" spacer up front, then match height the rear with a 1-3/4"(?) spacer, Trackick strut mounts, add 1" body lift for Sami (minimal to hope steering shaft could be extended without major re-work). Looking to go 31-32's. Will be adding custom front/rear bumpers, front winch, rocker skids, belly pan, t-case gears (maybe doubler instead), looking at an anvil with Kerry's cv's for the front, then lockers with gears (if possible - I know not the rear, but maybe front).
You previously went with the RRO spacer lift of 1-1/8"?
With Calmini's lift, what was supplied for the rear suspension with the 4 separate trailing links and the track bar? What did you do with the tie rod links with the lift since it's a rack and pinion setup?
