71817G-16LUN Lunati SB BB Chevy Hydraulic Race Flat Tappet Lifters

All of the components of the Lunati hydraulic race lifters are held to higher tolerances for superior performance. The plunger has a much tighter fit to the body, which reduces the amount of leaked pressure, keeping the lifter stiffer and more responsive. The one-piece pushrod seat is heat treated, which prevents the seat from damage and is equipped with a heavy duty snap ring to reduce wear and increase durability. The hydraulic race lifters have a pre-load that can be set to .000"-.030" and are the best option for racers looking to go beyond a replacement lifter.
