P2R Crank Washer Kit

P2R Crank Washer Kit for Honda J-Series Engines

The P2R Crank Washer Kit provides a precision-engineered solution for engine builders performing hybrid Honda J-series swaps. By extending the crankshaft interface, this kit ensures proper flywheel fitment on engines where the crankshaft does not naturally extend far enough to meet transmission requirements.

This kit is an essential component when installing a 2009 or newer J-series crankshaft into an older generation J-series block, allowing for seamless integration of high-displacement internals into earlier chassis.

Key Features

• **Precision Extension:** Extends the crankshaft interface to ensure proper flywheel fitment and alignment.
• **Complete Hardware Kit:** Includes eight OEM Honda long flywheel bolts for a secure, factory-grade installation.
• **Hybrid Compatibility:** Specifically engineered to facilitate the installation of modern J-series internals into legacy engine blocks.

Specifications

• 1x P2R Crank Washer
• 8x OEM Honda Long Flywheel Bolts

Fitment / Applications

• Honda J-Series Engines
• 2009+ J-Series Crankshafts (e.g., J37A4) into older generation J-Series blocks (e.g., J32A3)

Notes

• 2009 and newer J-series crankshafts feature a crank position trigger (pulse plate) bolted to the end of the crankshaft.
• Machine work is required to fit 2009+ crankshafts into older generation blocks.

Pro Tip: Verify all necessary machine work on the 2009+ crankshaft is completed before installing the P2R washer and flywheel assembly.
