Suspension Engineering Camaro Firebird Strut Shock Tower Brace 1993-2002 (Red or Black) 33-1010

Fit perfect

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.

Easy Transaction

Berry had what I was looking for, so I researched them a bit and saw many good reviews, so I moved forward. Transaction was easy, add to cart, enter address and email, checkout, pay, then emailed a receipt and updates throughout shipping until delivered about a week later. Would definitely purchase from Berry again!

AMAZING COMPANY

I ordered an x pipe for my Silverado to go with some long tube headers. When I placed my order I got the one for the newer body style truck and their customer service got back to me within the hour to get my order changed. If your looking for any truck parts definitely go through these guys!

Speed Engineering Silverado & Sierra True Dual X-Pipe System 1999-2018 (UNIVERSAL) 25-1006

Excellent price and fast ship

Loved these so much I just ordered ANOTHER set for our 69 Chevelle with a 6.0l! Despite what the internet says, these actually did fit my 55 Chevy bel air with a 6.0l LS. Cleared steering box, had to trim Pitman arm slightly. Cant beat the price at Berrys. All in all, its our 3rd time buying these headers.
