GPM Racing 1144 Steel Front / Rear High-Speed Ring Gear, Worm Gear 2T/14T for Axial 1/30 SCX30 Ford Bronco 4x4 RTR Brushed Rock Crawler (SCX30/0214TS)

Precision replacement ring and worm for 1/30 SCX30 crawlers

The GPM SCX30/0214TS 1144-steel ring and worm gear set is engineered as a durable replacement for 1/30 SCX30 brushed rock crawlers. The 2T/14T high-speed worm profile combined with a hardened steel finish provides a robust metal option to replace worn factory plastic or softer metal components while maintaining original drivetrain geometry. This kit is intended for professional hobbyists carrying out gearbox service, repair, or tuning.

Service and setup recommendations

• Fitment: Manufactured to match SCX30 drivetrain geometry; verify axle and gearbox alignment and ensure concentric mounting during assembly.
• Gear mesh: Set precise backlash using calibrated shims or adjustable mounts; avoid excessive preload to prevent undue bearing and pinion loading.
• Lubrication: Apply a thin, metal-compatible gear lubricant to the contact surfaces to minimize initial wear and reduce friction; inspect lubricant retention after run-in.
• Break-in: Execute a controlled low speed, light load break-in sequence to allow mating profiles to conform without inducing stress risers.
• Inspection: Conduct periodic inspections for burrs, tooth damage or misalignment after off-road use and clear debris from gear teeth.

Includes 2pcs: Ring Gear and Worm Gear (2T/14T).

What inspection steps should a technician follow when fitting this kit?

Confirm gear concentricity and pinion clearance, establish correct backlash, and perform a hand-rotation check before fully torquing mounts to ensure no binding.

Which lubrication practice best suits these hardened steel gears?

Use a light grease formulated for metal gears applied thinly to tooth flanks; heavy pastes should be avoided to reduce grit pickup and preserve tooth geometry.

Are any adjustments expected after the initial run-in?

After a controlled break-in, recheck mesh and fastener torque and make micro-adjustments with shims or mount position to maintain optimal contact pattern. Write Product Review Please sign in your account before you can write any review. Sign In Close
