Katech Spec Johnson 2110-K .8422" ± .0002" LS/LT True Drop-In Hydraulic Roller Lifter Set

Katech Spec Johnson 2110-K .8422" ± .0002" LS/LT True Drop-In Hydraulic Roller Lifter Set

Precision-Ground for Controlled Oiling and Stable Valvetrain Performance

The Katech Spec Johnson 2110-K LS/LT Drop-In Hydraulic Roller Lifter Set combines genuine Johnson 2110-K hydraulic roller lifters with Katech’s precision outside diameter specification for high-performance LS and LT engine applications. Each lifter is precision ground to Katech’s .8422" ± .0002" outside diameter specification to provide a consistent dimensional starting point when establishing lifter-to-bore clearance.

Designed as a true drop-in lifter for engines using OEM-style lifter guides and trays, these lifters provide precise hydraulic response and controlled leakdown without requiring a link-bar lifter conversion. The cold-forged, extra-long piston is precision ground and fitted to deliver predictable leakdown characteristics and consistent lash control when paired with the appropriate camshaft profile, valve spring pressure, preload, and valvetrain geometry.

A high-flow, quick-reacting disc-style check valve supports hydraulic stability at elevated engine speeds, while precision oil metering provides proper lubrication to the rocker arms without excessive oil loss through the lifter circuit. Cold-forged, heat-treated steel bodies, precision needle roller bearings, and high-chromium steel axles provide the durability required for demanding street and racing engine combinations.
