Replace your leaking or inoperative hydro boost unit with this OE replacement GM Assembly. This hydro boost is a direct replacement for 2011 GM 2500HD & 3500HD Duramax and 6.0L Equipped Trucks.
With slight modification of the booster push rod, this hyrdoboost can be used on 2001-2010 trucks to aide in curing the notorious low spongy pedal feel.
See how people are doing the swap @ DuramaxDieselForum.com
We do recommend purchasing a new GM 15048329 rod retainer for your install.
