Use the spec pages below to help you understand what features this product has. This set of a-arms is for the extreme rider or racer, someone who wants to maneuver quickly through the woods or other tight areas or someone who jumps high and lands smooth. The Maximum Ground Feature makes going over boulders, deep ruts, trees, roots, and any other rugged condition that the trail might bring, an easier task. Fine tuning your caster for each track is simple with the SLICAST ™ feature. With the needle bearing and seal design feature the bearing end of you’re a-arms will hold up to the dirty and watery atmosphere that you ride in. Long Travel shocks are a must for performance. Made from 4130 Chromoly Steel, fully TIG Welded, and Powder coated with a glossy finish that houses that HOUSER Logo, this a-arm set not only has the look, but it will hold up to anything that you can put it through.
