XTREME MOPAR HYDRAULICS (.904" MIN. TAPPET)
Xtreme Energy designs optimized for use with .904" minimum tappet diameters. The additional velocity allowed
with the Chrysler/Mopar .904" tappet results in more area and more lift than any of our other comparable hydraulic
designs. These are the best large tappet hydraulics ever.
