Ring Gear/Diff/Pinion Gear: 9579R
Upgrade your high-speed RC car durability with the official Traxxas Machined Differential Ring and Pinion Gear Set. CNC-machined from a solid block of high-grade steel, this heavy-duty spiral-cut 43-tooth ring gear and 10-tooth pinion set delivers superior strength for relentless extreme bashing action. Perfectly designed to replace stock differential components in your Traxxas Sledge, it minimizes backlash while maximizing traction and surface contact.
When putting maximum power through your Traxxas Sledge 1/8 scale brushless monster truck, standard gear assemblies can experience massive load stress. The Traxxas Machined Differential Ring and Pinion Gear Set solves this by utilizing precise spiral-cut teeth that mesh smoothly and evenly. The slight curve in the gear teeth maximizes overall contact surface area, which drastically reduces gear backlash and wear while transferring maximum torque to all four wheels. Whether installed in the front or rear differential housing, this CNC-machined steel gear upgrade ensures ultimate durability and long-lasting drivetrain reliability under extreme off-road conditions.
Will the Traxxas Machined Differential Ring and Pinion Gear Set fit both front and rear differentials on the Traxxas Sledge?
Yes, this machined gear set is designed as a direct fit for either the front or rear differential assembly on the Traxxas Sledge (Model# 95076-4).
What are the performance advantages of installing the Traxxas Machined Differential Ring and Pinion Gear Set?
The spiral-cut teeth provide a larger surface contact area compared to standard straight-cut gears, which significantly reduces drivetrain backlash, decreases gear wear, and delivers exceptional strength to handle high-voltage brushless power.
What gear ratio does this Traxxas Machined Differential Ring and Pinion Gear Set provide?
This gear set features a 43-tooth spiral ring gear and a 10-tooth spiral pinion gear, creating a durable 4.3:1 differential gear reduction ratio for maximum power transfer.
