Same manufacturer S&S uses but these are their high performance lifter.
Replacement hydraulic tappets for all Big Dogs with 107" and larger Super Sidewinder and SSW+ motors.
NON-HL2T lifters are
HERE
The HL2T is designed to limit the travel of the hydraulic lifter making it impossible for the lifter to collapse. Stronger valve springs are often used to avoid valve float at high rpm. The HL2T kit prevents high valve spring pressure from collapsing lifters. With the HL2T Kit installed, stock hydraulic lifters work like solid lifters at high rpm, while retaining normal hydraulic function for minimal noise and maintenance under normal conditions. Another advantage of the HL2T kit is that if a valve is held open when the engine is not running, valve spring pressure will not cause lifters to bleed down and collapse. Collapsed lifters can cause hard starting and excessive valve train noise when engine is restarted. Adjustable pushrods must be used with the HL2T Kit.
Set of 4, includes HL2T limiter kit
Features and Benefits:
- Direct Roller Pin Oiling for better lubrication
- Extreme Engine testing by the manufacturer has proven this system extends the life of the lifter and cam by up to 300%
- Larger inner bearing race reduces stresses to increase axle, bearing, and roller life: the S&S inner bearing race is .123" larger in diameter than the "raceless" roller axles currently used by some manufacturers
- Improved inner race-roller design allows use of more, and larger bearings to increase load-carrying surface area, further reducing stress and wear in the critical roller area.
- Redesigned plunger assembly better withstands forces associated with heavy-duty valve springs and cams typically used in high-performance applications.
- Revised metering device precisely controls oil delivery to top end, insuring rapid lifter pump-up and reducing possibility of oil starvation to bottom end
- Each lifter body and plunger assembly is hand-fit and then pressure-tested to insure correct operation
- Set of four, with HL2T limited travel kit
Don't let people, or the so called difficutly of setting them, dioscourage you from purchasing the HL2T spacers.
HL2T Limiter Lifter setting
- Cylinder to TDC
- Remove slack, turn the pushrod adjustment out until it just starts to make contact with the lifter and rocker
- Extend the pushrod four complete turns
- Wait 10-20 minutes for the lifters to bleed down
- Turn the pushrod adjustment in approximately one complete turn
- You will feel when the valve closes as the pressure as your turning will suddenly release
- Turn the pushrod back out until you feel the pressure just start
- At that point turn the pushrod in a 1/4 to 1/2 turn and lock it down with the lock nut
- Your ready for the next cylinder
