Tired of your rear tires leaning in or out? Prevent premature wear on tires and suspension components by eliminating camber on your Can-Am Defender. Correct your rear suspension geometry with S3 Power Sports' Rear Adjustable Upper A-Arms. Our HD zinc-plated adjustable bushing tubes allow you to calibrate your rear camber to get that factory ride and appearance back. Built from thick-walled chromoly tubing, these a-arms will withstand the biggest tires and nastiest terrain. Our Rear Adjustable Upper A-Arms are a direct bolt-on replacement for both rear upper a-arms, and allows you to utilize OEM hardware.
