No. If you have more distance between your bump stop and where it meets the axle vs the length of your shock piston your shock will fully compress before your bump stop can stop your axle from articulating causing damage to your shock.

so with the RC 2.5" lift and 2.2 shocks do you need extended bump stops running 31s??
its all going to depend on the compressed shock length...you need to find that out for front and rear. my suspicion is rears definitely will require at least 1-1.5" and the fronts may require 0-1.5"...again it depends on the compressed shock length.
in front, 13.5" compressed length shocks will fit into the stock location, without bumpstop extensions, with 31s. 14.5" requires 1" extensions, 15.5" requires 2" extensions, and so forth. In the rear 12" compressed length won't require any bumpstop extension...13.25" would require 1.25" bumpstop, 14.5" would require 2.5" bumpstop...and so forth.
Don't forget guys that the bigger the tire, the more strain on the weak D35 rear axle. I'm putting 33's on mine but am always going to have to think about how I use the throttle in fear of breaking down on the trail.
Right now im running the rc 2.5 lift on my stock 30 x9.5 x 15 bfg at's on canyon rims. she looks ok for now but im probably going to go up to 31's. have a 2000 4.0 5 speed manual. with a d 44 limited slip rear and and d 30 front running 3.73 gears.
