Designed for the extremes of racing use, all Function7 lower control arms are precision machined out of 7075 aluminum for maximum strength and then treated for corrosion resistance. Every arm is tracked in every step of the manufacturing process, and each arm is individually serialized and barcoded for quality assurance.

High quality custom-made polyurethane bushings (manufactured to our specifications by Energy Suspension) provide extended life while retaining excellent performance characteristics.

Aluminum CNC bushing inserts prevents rust related issues found on stock bushings.
