These 6061 billet aluminum knuckles are a factory GM replacement. These knuckles are designed to clear a 15” rim. This is done by moving the steering arm in so the factory tie-rod location changes. These knuckles work with stock kingpins and spindles. They cut 18lbs compared to the stock cast-iron knuckles.

Our knuckles are currently made to order and not available for immediate shipment. They are still available for purchase, yet we recommend contacting us to discuss specific lead times.

This item is proudly designed, engineered, and manufactured in house at IMS.
