2771004x, Hydro-Boost Repair Kit Seal Leak Repair Universal Kit Fit for Ford GM and Chrysler 2771004

I have a JD6 model hydroboost this kit does not come with proper sized o-rings to replace everything and the check valve failed after only driving 50km leaving me stranded on the side of the road and getting the truck towed home I recommend buying a new hydroboost instead of this kit

Used this kit to rebuild and reseal the Hydroboost on my 2006 Chevy Express 3500 service van. Super simple install, and everything fit perfectly. The only part I didn’t use was the small aluminum valve—I reused my original. So far, it’s been going strong for about 9,000 miles with no leaks. Great value and definitely worth it for anyone doing a proper rebuild. Instructions were lacking but as a mechanic and a little youtube university I knew what needed to be done.

Ordered two sets, Items came quick but no step by step instructions as listed.

Not great parts not included,seal still leaks

This is a great seal kit good product had good quality o-rings and parts thank you work great fit perfect great price
