These durable, great looking adjuster arms are custom made for us at Motorsport. Over time, the factory adjuster arms tend to bend, crack, and eventually break (usually when you are adding tension to the fan belt). Our adjuster arms are significantly more durable while also making it easier to add tension to the belt. They consist of a billet aluminum center, adjustable rod ends, and include all necessary hardware for mounting. The arm is adjustable from 5 5/8" (closed) to 7 3/4" (open), making it easy to adjust the tension on your fan belt.
