This Billet steel crankshaft has been meticulously designed to be the best K Series Billet crankshaft currently available.

It incorporates all of the best design features of the more expensive crankshafts and even has several further innovative features, such as, the oil galleries being oblique to the bearing surface and unlike some other steel cranks the counterweight design is suitable for heavy metal insertion.

It is gas Nitrided for strength, with hollow journals for lightness and although it is manufactured from the toughest EN40B steel it is still almost 1 KG lighter than the OE crankshaft.

Installing a lightweight balanced crankshaft can enable not only higher RPM which in turn creates BHP, it also puts substantially less strain on the bearings thus prolonging the life of the engine, as most of the forces are created by out of balance heavy crankshafts.

This fits the following models:

  • S1 K SERIES ELISE
  • S2 K SERIES ELISE
  • S1 EXIGE
  • LOTUS 340R
  • S1 MOTORSPORT ELISE / EXIGE
