GPM Racing 20CR Steel Spiral-Cut Ring & Pinion Gear Set 32T/9T/1.35 Mod for Axial 1/6 SCX6 Jeep JLU Wrangler 4x4 Rock Crawler RTR (SCX60932TS)

Precision spiral-cut ring and pinion for SCX6 applications

This GPM aftermarket ring and pinion pair is engineered as a replacement drivetrain gearset for the AXIAL SCX6 platform. Manufactured from hardened 20Cr carbon steel with a dark protective finish, the helical spiral-cut tooth profile promotes broader contact patches and reduced peak stress compared with straight-cut gears. The set is specified at 1.35 module with a 32T ring and 9T pinion for installation within the axle differential housing.

From an engineering perspective the parts transmit motor torque through the differential to the axle outputs while the spiral geometry helps attenuate impact loads and noise when shimmed to correct mesh. This set is presented as a higher speed ratio alternative to the factory 12/43T 1.0 mod gear set referenced by AXI252007; confirm all dimensional clearances and mesh pattern prior to final assembly.

Technical fitment notes: ensure pinion seating is concentric on the motor output or diff journal for the 1.35 module, establish a measured backlash to protect tooth roots, inspect bearing runout and diff housing alignment, and apply an appropriate gear lubricant. Perform a controlled low-speed break-in and then verify mesh and noise level. Intended for model use only.

Packing includes

• 32-tooth diff spiral cut ring gear – 1pcs
• 9-tooth spiral cut pinion gear – 1pcs

For hobbyists seeking a precision hardened-steel option on SCX6 crawlers, this spiral-cut gear pair provides improved contact distribution and durability when installed with correct gear mesh and bearing checks.

Which components are supplied?

Supplied parts are one 32-tooth spiral-cut ring gear and one 9-tooth spiral-cut pinion gear for differential installation.

What machining and material standards apply?

Gears are hardened 20Cr carbon steel with precision tooth geometry to improve contact patch and reduce stress concentrations under load.

Do I need special tools to set mesh?

Standard diff setup tools and feeler methods are sufficient; use proper shims or pinion shims and verify contact pattern with gear marking compound or by feel.

Any final assembly recommendations?

Check bearing endplay and diff case alignment, apply suitable gear grease to the teeth, perform a brief low-speed break-in, then re-inspect mesh and noise before full operation. Write Product Review Please sign in your account before you can write any review. Sign In Close
