Team Associated Enduro Stealth X Gearbox Kit

At the heart of the Enduro is the revolutionary Stealth(R) X gearbox. Although the exterior appears to have a conventional 3-gear transmission look, the inside is far from conventional. The Stealth(R) X features the ability to adjust the rear drive ratio independently from the front drive across three levels: stock overdrives the front end 5.7%, option 1 provides a one-to-one drive ratio front-to-rear, and option 2 overdrives the front end 11.83%.
