Customer Reviews
Came with everything I needed and mounted in perfectly, great product and great company👍🏻
Perfect!!
This kit was a dream come true. Everything bolted up super easy and the new lines were 10 times easier to thread on compared to the oem metal crap. I will be highly recommending this to all friends with the infamous and heat susceptible 4l60e transmissions.
Everything fit perfect has everything included in the kit that I needed I’ve had it on for about a week now it fits and looks nice and my trans temps are down about 40 degrees only thing I wish it had was something for horn relocation I had to make my own bracket for that
Everything fit perfect! Shipping was very quick and the quality of parts is top notch!!
