See Why Nothing Stops the Full-Size Traxxas Summit
The Traxxas Summit introduced the hobby world to remotely-operated T-Lock™ differentials, high/low transmission, and rocker-actuated suspension. Never before had this much technology been packed into a large-scale waterproof truck. Outfitted with massive Titan 775 power, the Summit redefined off-road adventure with its go-anywhere capability and high-speed fun. Watch the Summit claw its way over rocks, streams, and anything else that gets in its way in this new action video.
At your command, the servo-actuated T-Lock™ system engages eight steel drive dogs to lock the differential. Match the locking mode to the challenges of the terrain; Summit’s T-Lock differential system allows you to select front-lock for dig-style turns in tight quarters, front and rear lock for total climbing traction, or front and rear open differentials for optimum handling and a tight turning radius.
Not only was Summit the first truck to offer remote locking diffs, it’s also the only truck equipped with a remote-shifting High-Low transmission. In low gear, Summit’s 70:1 final-drive ratio turns rpm into pure torque to power up and over any obstacle that dares to get in the way. Upshift to high for a 25:1 ratio and all the speed you need to attack jumps and make tracks in a hurry.
