Are you looking to lighten your driveline? Looking to add a little more shine to your race car?

Look no further! Speed Doctor Racing Components has developed the absolute lightest lug nuts for drag racing on the market for 5/8" rear studs. Made from aerospace quality billet 7075-T651 aluminum which is considered to be stronger than some mild steels, these will yield a 40% weight savings over standard steel nuts. Lighter rotating mass equals faster speeds and quicker elapsed times! These are the only NHRA approved lug nuts and have passed all stress tests with flying colors. These use a 15/16" 12 point socket for installation and torque to 90 ft-lbs. These are made to exacting tollerances on precision CNC machining centers and are individually hand inspected before the customer receives them.

Andy Frost has now become an exclusive European dealer for Speed Doctor racing components wheel nuts.

The nuts are also available anodised in a variety of different colours at a little extra cost.
