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 Installation Fixture. 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.

Oil flow should never be restricted to any Jesel Precision Roller Lifter.

LS-1 AND LS-7 RETAINER KIT

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