Hardened Locks, 3/8" Four Groove

Four Groove Locks to suit Chrysler w/ 3/8" Stem Valves

Order a full set of hardened locks (16 pair) for SB, BB and 225 six cylinder Chrysler products.

These are used to either replace old std four groove locks or to be used when four groove valves replace 2 groove.

Chrysler use several different lock configurations. Four, two and single groove.

If at some point you end up with four groove replacement valves when the originals were two groove, just use these locks with the new four groove valves and you're good to go.

If you're converting to single groove (square groove) simply order a set of our 3/8" X 7 degree locks.
