ALTA 02-06 Mini Cooper S/JCW & 02-08 S/JCW Convertible R53 Lightened Crank Pulley 0%
ALTA lightened crank pulley replaces the heavy stock unit on R53 chassis Mini Cooper S models. It fits 2002-2006 hatchback S and JCW variants plus 2002-2008 convertible S and JCW models. Removing 2.1 lbs of rotational mass lets the supercharged engine accelerate quicker with crisper throttle response while 0% underdrive keeps accessory speeds at stock levels.
Key Features
- Weight Savings: Reduces pulley mass from stock 46 oz to 12.5 oz for 33.5 oz or 2.1 lb drop that frees up engine power.
- Material Construction: CNC machined from billet 6061-T6 aircraft grade aluminum for strength and light weight.
- Finish Quality: Black anodized surface provides corrosion resistance and long lasting appearance.
- Underdrive Ratio: 0% design matches stock outer diameter to prevent slower alternator water pump or power steering operation.
- Balance Engineering: Precision machined and balanced to reduce vibrations and ensure smooth high RPM operation.
