The Direct Shot HA2104SE is not just a replacement lifter; it is a cooling and lubrication system for your camshaft. Standard lifters rely on "splash" oiling to lubricate the roller. At idle or under high-heat towing conditions, that oil often fails to reach the needle bearings, leading to seized rollers and destroyed camshafts.
The Direct Shot design features a patented oil injection port that delivers a pressurized stream of oil directly to the axle and needle bearings, ensuring they stay lubricated under every operating condition.
Pressure-Fed Bearing Lubrication: The "E" in the part number signifies the Direct Shot® system. A precision-machined passage bypasses the lifter body to "shoot" oil directly onto the roller's needle bearings. This reduces friction and heat by up to 30% compared to OE lifters.
"Slow Leak Down" (S-Series) Stability: This is the "S" designation. These lifters are machined to a tolerance of 0.000120” (1/30th the thickness of a human hair). This ultra-tight fit prevents the lifter from "bleeding off" or collapsing under high-pressure valve springs, keeping your valve timing precise even at high RPMs.
Anti-Clog Oil Band: Unlike other brands that have an exposed oil hole prone to catching debris, Direct Shot utilizes a proprietary recessed oil band. This acts as a secondary filter to ensure that only clean, pressurized oil reaches the sensitive needle bearings.
Mechanical-Like Performance: Because of the slow leak-down rate, these lifters provide the stability of a solid mechanical lifter with the quiet, maintenance-free operation of a hydraulic unit.
Forged Steel Bodies: Every lifter is manufactured in Muskegon, Michigan, using 100% American-forged steel. The roller is made from 52100 bearing steel for maximum hardness against the cam lobe.
