Precision machined gears use a helical tooth profile to provide smoother, quieter operation and increased surface contact for improved torque distribution compared with straight-cut gears. Hardened steel construction resists wear and deformation under load, enhancing drivetrain durability during aggressive driving and high-power use. Designed to fit directly into the Mini Maxx front differential housing using standard bearings and hardware without modification. Improves traction and differential action for better handling on varied terrain.\u003c\/p\u003e\n\u003cp data-start=\"698\" data-end=\"1260\"\u003e• Hardened steel helical ring and pinion gear set for long wear and strength.\u003cbr data-start=\"787\" data-end=\"790\" data-is-only-node=\"\"\u003e• 39T ring gear paired with 10T pinion for correct Mini Maxx front diff ratio.\u003cbr data-start=\"868\" data-end=\"871\"\u003e• Helical tooth profile for smoother, quieter engagement and extended gear life.\u003cbr data-start=\"951\" data-end=\"954\"\u003e• Direct replacement for stock differential gears using factory components.\u003cbr data-start=\"1029\" data-end=\"1032\"\u003e• Enhances front drivetrain durability under high torque conditions.\u003cbr data-start=\"1100\" data-end=\"1103\"\u003e• Helps improve traction and power distribution during acceleration and cornering.\u003cbr data-start=\"1185\" data-end=\"1188\"\u003e• Precision machining maintains accurate gear mesh and reduced backlash.\u003c\/p\u003e","brand":"Hot Racing","offers":[{"title":"Default Title","offer_id":50871432872223,"sku":"210000029637","price":29.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0897\/0426\/8063\/files\/lm6bgovgpq5r2osztmde.png?v=1745597883","url":"https:\/\/newsunracing.com\/products\/hrsmmx9390f-steel-helical-differential-ring-pinion-gear-for-traxxas%c2%ae-mini-maxx%c2%ae-front-39t-10t","provider":"New Sun Racing","version":"1.0","type":"link"}
