My GM455(99 C3500HD) chassis had a 40mm bore vs the 36mm bore my lmm has
The part number for said MC nm2754 via Autozone
Though it also has dual 66mm piston caliper and 14" disc brakes..

Haven't had time to look closely at either yet.. But plan on doing so


Getting out of my hd truck and then getting into the lbz I miss the brakes of the hd truck but love the power of the duramax . Maybe someday I will have the best of both worlds.

So the consensus is an lmm hydroboost will fit the older trucks and make the brakes and steering more responsive like an lmm? Would you need to get an lmm mc too to get the full effect or is just the hb enough?
