Ordered smaller 1 3/4 headers on accident, I messaged them, they responded within a couple minutes. Helped me upgrade to the bigger 1 7/8 in headers. Super good customer service! & headers fit and sound great!

The siping tool is sturdy and well built, worth spending a little more for.

For me the ball joints came bolted in on both upper control arm.
The also make it easier for future bushings replacements, by not being pressed fit. They also have grease ports to grease the bushings.

X-pipes are cool, but give Brenon a gosh darn raise! I’ve been waiting for these x-pipes since May and he was able to get them to me within a week. God bless, I’ll never forget that.

Berry had what I was looking for, so I researched them a bit and saw many good reviews, so I moved forward.

Would definitely purchase from Berry again!
