  • SPOOL Billet 4340 81mm Stroker Crankshaft

Toyota 4AGE 81 mm Billet 4340 Stroker Crankshaft

Full billet 4340 Nitrided and Balanced Crankshaft

Note: The 4AGE engine in its factory form has a 81mm bore and 77mm stroke, giving a displacement of 1587cc

Using the 81mm stroker crank, std length conrods and custom pistons, the displacement is increased as follows:

  • 81.5mm bore and the 81 mm stroker crank = 1690cc / 103cc increase
  • 82 mm bore and the 81 mm stroker crank = 1711cc / 124cc increase

With the increased cubic capacity from the 108mm 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.

Note: Clearancing of the cylinder block is sometimes required.
