Function 7 Ultralight Rear Lower Control Arms

About Function 7 Control Arms
Designed for the extremes of racing use, all of our 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.

Bushings or Bearings?
Function 7 control arms are available with spherical bearings instead of bushings. If your car is driven daily and you attend a local road race or auto cross every now and then the bushings will be the perfect choice for you. The polyurethane bushings are forgiving enough for potholes and everyday encounters yet stiff enough to still provide you with the stiffness and response a track car needs.

The spherical bearings are for your hardcore racing needs. They feature oversized teflon-lined bearings and rotate a full 360-degrees which spreads the bearing load evenly and eliminates any play.

Features
• 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.
• Modular design allows individual component replacement and makes bushing rebuilds simple.
