🔧 What's Included — and Why It Matters:
-
✅ 6x 150mm APR Liners
Anti-Polishing Ring liners prevent carbon buildup at the top of the cylinder, reducing ring wear and improving oil control—especially helpful for engines that idle frequently or run under heavy loads.
-
✅ Pistons with Rings, Pins, and Clips
Complete piston assemblies designed to match OEM spec 4376175 for tight compression, fuel efficiency, and long-lasting performance.
-
✅ Rod Bearings, Main Bearings, Thrust Washers
All new bottom-end internals to ensure a smooth and quiet-running crankshaft.
-
✅ Full Upper & Lower Gasket Sets
Everything you need to seal the top and bottom of your engine: head gasket, pan gasket, valve cover, seals, and more.
-
✅ Thermostat (Included!)
Helps regulate operating temperature, improving thermal stability and protecting the engine during start-up and operation.
-
✅ Piston Cooling Nozzles (Included!)
These spray oil onto the underside of the pistons to reduce heat and prevent damage during extended high-load driving.
