It might be different with a 4x4 solid axle, but on my 2wd i think i have pretty much tested my spacers, ive jumped my truck, hit stuff hard, mud, water, pretty much everything and my springs havnt popped out of there seat. if anything i think putting a body lift would be a worse idea since now your engine is exposed more to water, mud, and anything else out on the trails. unless you make or buy a wheel well extension. 4wheel parts prolly made more money off the body lift.
