Application Details

HT-969 is a direct-fit engine valve lifter for vehicles that call for a hydraulic, flat-tappet style lifter with a 0.440-inch wide oil ring groove. This part number is commonly searched for Chevrolet C/K trucks, GMC P3500 and G-series vans, and classic GM passenger cars such as the Buick Skylark, Pontiac Grand Prix, and Oldsmobile Cutlass Supreme. This part cross-references Bosch H301 and Four Seasons 36969 for the same application.

What It Helps Fix

• Valve train noise caused by worn hydraulic lifters
• Rough idle from inconsistent lifter operation
• Loss of valve lift control in flat hydraulic lifter engines
• Oil control issues in applications requiring a .440" wide oil groove
• Restoration needs for OE-style engine rebuilds

Installation Notes

Verify the engine uses flat hydraulic lifters and the correct 0.440-inch wide oil ring groove before installation. Confirm the application against the vehicle listing for your exact year, make, and model, especially on GM platforms and Jeep Wagoneer/CJ applications. HT-969 is listed for N/A position applications and should be matched to the engine’s original lifter specification during service.

Quality Assurance

Sealed Power parts are manufactured with modern materials and controlled production processes to meet the demands of current and legacy engines. HT-969 is an OE replacement engine valve lifter built to support consistent fitment across the listed applications.
