Katech Spec Johnson 2116 LSR LS/LT Tie-Bar Reduced Travel True Drop In Hydraulic Roller Lifter Set

Katech Spec Johnson 2116 LSR LS/LT Tie-Bar Reduced Travel Hydraulic Roller Lifter Set

Precision Ground for Controlled Oiling and Stable Valvetrain Performance

The Katech Spec Johnson 2116 LSR LS/LT Tie-Bar Reduced Travel Hydraulic Roller Lifter Set combines genuine Johnson 2116 LSR hydraulic roller lifters with Katech’s precision outside diameter specification for high-performance LS and LT engine applications requiring a tie-bar lifter configuration. Each lifter is precision ground to Katech’s .8422" ± .0002" outside diameter specification, providing a consistent dimensional starting point when establishing lifter-to-bore clearance.

Designed with an integrated tie-bar system, each lifter pair is mechanically linked to maintain proper lifter orientation and consistent roller alignment on the camshaft lobe under elevated spring pressures and aggressive camshaft profiles. The reduced travel hydraulic design provides controlled plunger movement and stable valve motion in demanding valvetrain environments.

The cold-forged, extra-long piston is precision ground and fitted to deliver predictable leakdown characteristics and consistent hydraulic lash control when paired with the appropriate preload, valve spring pressure, camshaft profile, and overall valvetrain geometry. A high-flow, quick-reacting disc-style check valve supports hydraulic stability at elevated engine speeds, while precision oil metering provides rocker arm lubrication without excessive oil loss through the lifter circuit.

Cold-forged, heat-treated steel bodies provide excellent strength and wear resistance. Precision needle roller bearings and high-chromium steel axles support durability and long service life in demanding high-performance street and racing engine combinations.

Why Choose Katech?

The difference is in both the specification and the design. These genuine Johnson 2116 LSR hydraulic roller lifters are precision ground to Katech’s .8422" ± .0002" outside diameter specification, providing engine builders with a consistent dimensional starting point when establishing lifter-to-bore clearance in LS and LT engine applications.

Designed for applications where a tray-retained lifter is not suitable, the integrated tie-bar system maintains proper lifter orientation while the reduced travel hydraulic design supports controlled plunger movement and stable valve motion under aggressive camshaft profiles and elevated spring pressures. Combined with Johnson’s proven hydraulic roller design and Katech’s precision specification, these lifters provide the hydraulic stability, durability, and valvetrain control required for demanding street and racing engine combinations.

Precision Ground to Katech Specifications and Quality Controlled, these lifters reflect the same attention to detail found throughout Katech’s championship-winning engine programs. As with any precision engine build, final lifter-to-bore clearance, preload, spring pressure, tie-bar clearance, and overall valvetrain geometry must be measured and verified during assembly.
