This Engine Cylinder Sleeve (Liner) Set is the correct specification for the classic Jeep L-134 (4-134) Flathead engine. These sleeves are finished for standard size pistons, making them ideal for professional engine rebuilds, WWII restorations, and long-term reliability.
Over time, cylinder wear, scoring, and taper reduce engine efficiency in classic Willys flathead motors. This finished cylinder liner set allows the engine block to be restored to factory condition without replacing the block itself.
These liners are ideal for:
Full engine overhauls
WWII Jeep restorations
Standard bore piston rebuilds
Solving oil consumption and compression loss
Once installed correctly, they provide a fresh, durable cylinder surface ready for piston and ring assembly.
