The Trask Assault Series Swingarm is engineered to increase stability, strength, and precision handling on early Touring platforms. Machined from T6061 billet aluminum, it offers a lighter and more rigid structure than stock, reducing flex and improving control at speed. This design is proven on Trask race bikes and used by competitive teams in major bagger racing series.

Its modular layout allows for custom setup options, and adjustable shock positions make suspension tuning simple. The improved axle design replaces cam style adjusters for more consistent alignment and easier chain management. Each swingarm arrives raw and disassembled so builders can finish it to match their project.

Every kit includes stainless hardware, spherical bearings, and Delrin chain guides. It is designed to work with the stock brake caliper and mount. For radial caliper use, pair it with the Trask TM-3200-15 caliper mount.
