specialist Components are now able to offer bespoke billet steel crankshafts and H-beam or I-beam con-rods in low volumes to your custom design. These volumes can be as low as five crankshafts or three engine sets of con-rods, however discounts are available for higher order quantities.
We prefer to work from drawings wherever possible, as this gives the best possible result and shortest lead time. However it is possible to work from a sample part at a considerable additional cost.
Typical cost for a custom billet steel crankshaft is just £850 per part based on an order of 5. An order volume of 10 units, would reduce this price to £690 per crankshaft.
A set of custom H-beam billet steel con-rods for a 4 cylinder engine would cost around £550 per set for an order of 3 sets including genuine ARP bolts. An order of 5 sets of rods would cost £480 per set.
