Color: Silver

If you’ve got a 6.6L Duramax and Hydro-Boost brakes, this is the pump kit that gets the job done right — no guesswork, no junkyard parts, and no “good enough” solutions.

We built these High Performance kits for people who actually use their trucks — towing, hauling, or just plain working. Bigger internals mean more flow at lower RPMs, and the 1800 PSI relief valve makes turning big tires feel easy — no more fighting the wheel.
