Good quality and perfect fit

"Good quality and perfect fit from OEM. Shipping was faster than Amazon. If your in the market for some new lines definitely consider buying from here."

— Drew E. (5/5)

Quality

"Handed these to my mechanic who installed them. He advised they fit great and were nice thick lines that did not bend as they were installed. Delivery was fast too"

— Shawn P. (5/5)

Overall good.

"Material quality very good. Also they ship with dust cover caps which keep muck from getting in the lines during installation! 2 small issues: bend 1 coming out of the lower radiator port put the line touching the lower radiator hose. I think it could be about 15mm shorter to keep from rubbing. Also, the white plastic keeper rings for the e-clips were either too big or too soft of plastic and wouldn’t stay where they’re supposed to. Had to reuse my old ones. All that said, these are clearly made with care and attention. I would buy again on another vehicle."

— Morgan o. (4/5)

Factory fit. All bends set

"Factory fit. All bends set to OE design. Take your time installing. You'll get more clearance for install if you remove the starter and the front crossmember, as well as the skid plates"

— Thomas G. (5/5)
