SPOOL - Nissan / Holden RB30 - RB34 Stroker Crankshaft

Spool RB30 Full Counter weight 4340 Billet Crankshaft with a 94mm stroke.
RB34 Stroker Crank to suit Nissan Skyline RB30 and Holden RB30 VL Commodore engines
We have Pistons available to suit both Twin Cam and SOHC cylinder heads.

This is a true billet crankshaft machined from Billet 4340 core stock (not a cast forging blank that is final machined).

Each crank is machined from core stock 4340 on a CNC machine, then Nitrided and final ground.
We have customers making over 1000 hp with our billet crankshafts!

With the increased cubic capacity from the 94mm stroker crank, increases of up to 50% in torque and low to mid range power are achievable. Boost will come on earlier in the rev range and peak power will increase.
