Tool Steel Dog Bone Roller Lifters


Dog Bone Roller Lifters get their name from the O.E. style dog bone shape alignment plates that are bolted to the cylinder block for cam/roller alignment. Jesel’s Dog Bone Roller Lifters are lighter than traditional tie bar styles of lifters and can be easily installed in the home workshop using Jesel’s Dog Bone Drill Jig. These roller lifters are ideal for most forms of racing, available in lifter diameters of .842”, .875”, .905”, and .937”. The list of available roller diameters can be found in the chart at the bottom of this page. Standard Jesel features include full internal oil circuits, hard-coated steel bodies, and aluminum pistons with hardened-steel (centered and offset) pushrod seats.

For LS-1 and LS-7 applications, Jesel recommends the use of their Dog Bone Retainer kit. A direct replacement for the OEM plastic retainer, this precision machined retainer securely guides the lifter and prevents premature lifter bore wear.
