Race Cranks

944, 944 Turbo, 944S, 924, 944S2, 968 Race Cranks

To cross-drill your 944, 924S, 944S, 944 Turbo, or 968 crank $375

To cross-drill, knife-edge, balance, nitride, and micro polish your 944, 924S, 944S, 944 Turbo, 944S2, or 968 crank $850

To change the stroke of your crank from the stock 78.9mm (2.5 liter 944, 924S, 944S, 944 Turbo) to 88mm (3.0 liter 944S2 and 968) and cross-drill, knife-edged, lighten, balance, nitride, and micro polished $1,325

Note: All of our cranks have a hardening process called Nitride. This is a super hard treatment performed to the cranks after all machine work has been completed, to make the crank much more durable.  It is a must for racing applications!  This is the same process the factory uses on all of their cranks. If you send your crank off, or buy a crank from any other company, and they have done any machine work to the journals, they have cut through this super hard surface. Make sure you ask them if the crank has been "Nitride Hardened"!

Core charge on all 78.9mm cranks is $275

Core charge on all 88mm cranks is $450

When you return your rebuildable crank, we will refund the core charge.

If you do not want to pay a core charge, send us your crank and we will perform whatever service you want and send it back to you within two weeks.

All cranks are STD. - STD on Main and Rod Journals unless otherwise stated.

Designed for Race Cars and Performance Street Cars

More Power and torque from your engine due to smaller crank pulley drive size, smaller power steering (pulley on crank) drive size, larger alternator and power steering pulley sizes - Basically re-gearing the alternator, A/C and power steering to turn slower at high RPM. Also saves alternator, A/C compressor and power steering pump from damage when used at extended high RPM.

Under-drive pulley's have been used on all types of race cars and race boats for over 60 years, and are a proven way to gain free power!

CNC machined from billet aluminum and hard anodized in black, blue, silver, purple or red. They are much lighter than stock pulley's and look great!

They will not rust like stock painted steel pulley's. Direct bolt-in to stock location with no modifications required.

7 HP and 7 ft. lbs. of torque gain proven on dyno!

Individual Pulley Prices:

Crank Under-drive Pulley $135

Alternator Under-drive Pulley $85

Power Steering Under-drive Pulley (on crank) $65

Power Steering Under-drive Pulley (on Pump) $85
