HPI Savage 3-Speed Transmission

Take your HPI Savage (fits all Savage trucks -  X, XL, 4.6, 21, 25, & SS trucks) to the next level with the AWESOME 3 Speed Transmission!  You get more punch and higher top speed, the best of both worlds!  Faster track times, easier wheelies, blistering top speed, better fuel mileage, and lower engine temperatures are the result of this ultimate Savage upgrade.

Internally, the gearbox has been redesigned for extra durability and longer life. Hardened steel is now used for many of the gears and hubs, stronger clutch mechanisms were developed, as well as extensively lightened gears and hubs.  Shift points can be tweaked to fit the track conditions, and you will blow those 2-speed Savages away!


This is the complete 3-speed.  Installation is quick and easy. Built to the exact factory specs for a perfect fit, the 3 speed transmission bolts right in to all Savage trucks.
