Differential
Restore critical all-wheel traction, fix severe drivetrain binding, and split high-torque delivery safely across your axles with our premium selection of heavy-duty ATV and UTV differentials. Operating as the mechanical hub that allows your left and right wheels to rotate at different speeds during tight cornering, the differential assembly is vital for maintaining trail control and preventing tire scrubbing. Brutal shock loads from sudden rock transitions, extreme deep-mud tire spinning, and water contamination quickly chip gear teeth, shear cross-shafts, and ruin internal bearing races. At CG ATV & UTV Parts Shop, we stock precision-machined complete differential assemblies, front locking differentials, upgraded heavy-duty ring and pinion gear sets, and rugged replacement carrier spools.
Our domestic fulfillment channels process and ship orders daily from strategic distribution hubs across the country to minimize your garage downtime. Whether you are rebuilding a whirring rear differential housing with fresh high-capacity bearings or replacing an entire cracked front case before an upcoming mud event, our components provide exact factory-spec line alignments. Keep your 4WD system engaging flawlessly and push power directly down to the dirt.

Forged 8620 Chromoly Gear Sets vs. High-Stress Shock Load Shearing
Standard factory differentials are prone to failure when oversized mud tires bite hard on rocky surfaces, forcing a sudden shock wave back through the internal spider gears. Our premium aftermarket ATV and UTV differential internal gears are engineered from forged 8620 chromoly steel, case-hardened via deep gas carburization. This precision metallurgic process yields an incredibly tough outer wear-surface while preserving structural core elasticity to absorb violent impact spikes without cracking or fracturing teeth under high engine load.
To eliminate structural gear case deflection under torque, our complete housings are CNC-machined from aircraft-grade 6061-T6 billet aluminum or dense high-tensile nodular iron. This architectural stability ensures that the ring and pinion gear teeth maintain absolutely perfect gear lash and contact patterns, even under severe full-throttle load scenarios. Fitted with premium double-lipped nitrile seals and heavy-duty angular contact bearings, our assemblies lock trail water out completely while managing rotational stress seamlessly.

Gear Mesh Backlash Checking, Shimming, & Break-In Safety Guidelines
When assembling a replacement differential or installing new ring and pinion gears, you must use a dial indicator to verify gear backlash and apply gear marking compound to inspect the face contact patterns meticulously. Use precision hardened shims to reposition the ring gear carrier or pinion depth until the contact patch sits dead center on the gear teeth to prevent immediate gear howling or premature gear wear. Always utilize fresh, application-specific gear lubricants and clean internal magnetic drain plugs before sealing the housing halves. Perform a strict initial 5-mile low-speed break-in heat cycle, then drain the fluid to clear out micro-particles before tackling high-speed trails or heavy mud.
