    • Good parts Texas Speed Lifters
This product worked great on my 2010 Chevy 1500 5.3 liter. Fast shipping and all parts are original Texas Speed Products. I installed these over the weekend, and happy to have my work truck back running so I can go back to making money. Definitely would purchase from again.

One of the lifter trays was broken before ever being removed from the box and there was no damage to the box, as for the lifter performance I haven't finished the install so still hoping for the best
