Made in house by Hemi people for Hemi people. These are brand new Hemi rocker stands machined from T-6 Alcoa billet aluminum bar stock. No junk extrusions or castings here. Made for stock valve location heads with 1.875 to 2.000 spring height and .250 locating dowel. Our stands are machined to allow the use of spark plug tube cups and feature standard oiling to be compatible with all makes of rocker arms and shafts. Lighter, stronger and more accurate than factory or reproduction cast iron units. Infinitely stronger than the new split top design stands as the spring load is carried by the billet aluminum and bolt, not just a 3/8 stud as in the split tops. Unlike other budget stands out there, our kit comes complete. You’ll get 10 stands anodized Mopar blue with A.R.P. integral washers installed, 20 grade 8 shaft bolts and washers and a shim pack.
