"Very little bending great product"

— Noman (5/5)

Lines were great, took a

"Lines were great, took a whole week to get them. Pretty frustrating when they advertise free next day shipping."

— brandon k. (1/5)

assesment of lines

"bent fairly close, wasn't crazy about the shipping bend, you have to unbend and straighten, but I understand why they did it. I bent them back straight against rear tire, was nervous about kinking, but worked out. I have put on factory one piece before, liked that these lines were multiple pieces, much easier to install. still took like 6 hours to remove old lines and install new."

"Exact fit for my 2003 Silverado 1500hd. Very nice replicas!"

Well satisfied with everything minor adjustments

"Excellent service"

— Dennis T. (5/5)

Check line color coding to make sure it's correct.

"Lines fit well install was fairly straightforward. Second or third set I've installed from them and have always been impressed. Hooked up lines to color coded dots not realizing they were wrong and had the return line going into the vent. Got a mile down the road and ran out of fuel. Filled up noticed the leak. Figured it out. Swapped lines all good now."

Online chat was great to

"Online chat was great to verify I got the correct part. Website was easy to navigate. Price was a little high, but expect that for hard to find parts. Shipping was quick and my mechanic was pleased with the fit. I just wish there had been a stainless steel option."
