Barraxt
I can't beleive the S*&^t some of these 4wd companies (names consists of 3 letters) try to get away with.
I know that once a u bolt is taken off it should never be replaced as they stretch and twist and are no the same once removed, and you will find that just about all suspension manufacturers state that new u bolts are to fitted at time the suspension goes in otherwise your warranty is void. So why don't they know and understand this.
Two new u bolts cost us what $20-30 so to them its maybe $10 why risk a problem or reputation over $10.
I bet if you installed it yourself and did not put new u bolts on and something went wrong i know who they would of been blaming
