replace yours now before the factory ones break. FYI the breakage is caused by the exhaust swinging side to side stressing the heads. over time the heat from the exhaust is softening the steel. Replace every 4 years.

Fit my 08 Yukon 5.3 head and seem good quality with great value. Back left/passenger side was a booger though.

Originally I got a set of bolts through the dealer thinking keep it original, nothing better then that. Boy was I wrong the dealer bolts kept turning inside the block, come to find out the bolts I got from the dealer were for the newer cars that don’t have a cast iron exhaust manifold ( Header ). Found this set and wow the quality alone was fantastic compared to the other set of bolts I got, I put the bolts in and they went in with out any issue and when the bolt stopped turning it stopped. Great buy and quality

Got this for my headers on my LS1. They were a little long but I used some washers. they may of been long for the headers I have, others may have a different experience than me. I have S13 LS1 swap headers.
