Exhaust Actuator for Buell XB motorcycles S1138.1AA


Long since obsolete, we are now offering the replacement for the stock S1138.1AA Buell unit. We start with the Dorman actuator from a Jeep and use Lutz Gebhardt's creative design, which has enabled us to bring this to market (thanks Lutz!). The Dorman unit has stronger metal gears vs. the stock plastic ones.

Each unit is tested before shipping, and instructions are included.

Many of you know the advantage of using the stock muffler with the actuator, effectively creating two exhaust systems in one.
