Nitto Billet Crank Timing Gear & Washer Kit - Nissan RB20 / RB25 / RB26 / RB30 - Skyline / Skyline GT-R (R31–R34) / Stagea (WC34) / Commodore (VL)
A billet crankshaft timing gear and washer kit for Nissan RB20, RB25, RB26 and RB30 engines. It is designed for high-horsepower, high-revving RB and Nitto stroker engines in drag and circuit use, where the factory gear and keys are pushed hard.
Buy the full kit (timing gear, inner and outer washers and woodruff keys), or the timing gear, inside washer, outside washer or a single woodruff key on its own.
Note: Installation by a professional is recommended. Engine internals must be measured and set up by a qualified engine builder.
Features
- 4340 billet steel crank timing gear
- EN26 billet steel washers either side of the gear
- Nitto billet woodruff keys hold the assembly in place
- Designed for high-rpm RB and Nitto stroker engines
- Each piece hand checked by a Nitto technician
