SPOOL - Nissan RB26 - RB28 Stroker Crankshaft Description
Spool RB26 Stroker crank - * con rods not included *
Spool RB28 Full Counter weight 4340 Billet Crankshaft with a 77.7mm stroke.
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.
Rated at 1500HP plus
With the increased cubic capacity from the 77.7mm stroker crank, big increases in torque and low to mid range power are achievable. Boost will come on earlier in the rev range and peak power will increase.
