Came out of an 8.1 avalanche iirc. I used it for 2.5yrs and had no issues until I noticed the typical HB leak. I bought the rebuild kit but I don't have time to do all that, so I just got a rebuilt unit with all new hoses and master cylinder. All youd need is the tee fitting and the brake pedal. You can use it as is or rebuild at your pace. $150obo+ship paypald as gift or add 3%.

What you will get:
(1) Hydroboost unit
(1) Master Cylinder
(2) Pressure hoses
(1) Return hose
(1) Rebuild kit Kit 50 (2771004X) Hydro-Boost Repair Kit - Pirate Jack

Will ship from 92415 via UPS
