It is designed to fit seamlessly into compatible chassis, so you can bring your car back to ready for the track condition without complicated modifications. As drivetrain component, the differential assembly plays a central role in how your RC car delivers power to the tires It allows the left and right wheels to rotate at different speeds during turns, reducing tire scrub and improving cornering stability while maintaining consistent forward motion out of every bend. Built with alloy construction, this differential gear is designed to stand up to the demands of on the road and unpaved RC driving. The toothed metal annular gear gear provides clean engagement, while the silver-colored metal collars and black forked output couplings ensure a close fit to the drive shafts. A separate bevel gear component is included, giving you the key parts needed for a complete differential overhaul. This gear assembly is intended for manual installation, making it well suited for hobbyists who enjoy working on their RC vehicles. It is fits XV02, TT02, MB01, BT01, and XM01 chassis, so you can use it as direct replacement for a damaged stock differential or as an upgrade step a custom build project. By installing this 39-tooth alloy differential gear assembly, you can regain smooth, efficient power transfer through the drivetrain and enjoy more predictable handling on the track. Whether you are tuning for a race or easily renewing a well-used model, it delivers the reliability and precision you expect from a quality RC performance part\n\nOption: Red Xv","category":{"slug":"hobbies","label":"Hobbies & Collectibles","google_path":"Vehicles & Parts > Vehicle Parts & Accessories > Motor Vehicle Parts"},"product_category":"Vehicles & Parts > Vehicle Parts & Accessories > Motor Vehicle Parts","brand":"SuntekStore","condition":"new","price":"34.29 USD","price_amount":"34.29","currency":"USD","price_valid_until":"2026-10-31","tax":"US sales tax calculated at checkout (prices exclude tax)","availability":"in_stock","inventory_quantity":20,"max_quantity_per_order":10,"shipping":"US:ALL:Standard Shipping:12-22:0.00 USD","delivery_days":{"min":12,"max":22,"unit":"calendar_days_from_order","handling_business_days_max":4},"estimated_delivery":{"if_ordered_on":"2026-10-01","earliest":"2026-10-13","latest":"2026-10-23"},"ships_to":["US"],"shipping_cost":"0.00 USD","return_window_days":30,"return_policy":{"window_days":30,"window_starts":"delivery","condition":"unused, in original packaging","return_shipping_paid_by":"customer (we pay if the item is damaged, defective or not as described)","refund_method":"original payment method","refund_within_business_days_of_receipt":5,"how":"https://suntekstore.com/contact/ with the order number","url":"https://suntekstore.com/returns/"},"package_dimensions_cm":[6.0,6.0,6.5],"weight_g":90.0,"material":"Alloy","package_includes":"Differential Gear ×1","product_dimensions_cm":[3.96,3.96,6.1],"specifications":[{"name":"Tooth count","value":"39 cogs"},{"name":"Components","value":"Toothed metal annular gear gear, cylindrical central housing, silver-colored metal collars, black forked output couplings, separate bevel gear component"},{"name":"Compatibility","value":"XV02, TT02, MB01, BT01, XM01 chassis"},{"name":"Scale","value":"1/10"}],"image_link":"https://suntekstore-img.sfo3.digitaloceanspaces.com/p/1d/1d15d9fc902ebbea954469a1a8f929e72fb00a50.jpg","additional_image_link":["https://suntekstore-img.sfo3.digitaloceanspaces.com/p/6c/6c68ca3b5a6234f89588362b12e3992bbaca95f7.jpg","https://suntekstore-img.sfo3.digitaloceanspaces.com/p/f7/f7b3f3baa692b2e54f9dba5980d6385a38da8a4b.jpg","https://suntekstore-img.sfo3.digitaloceanspaces.com/p/63/632c6e3181682c48fec3c7a9e15a957d630009d3.jpg","https://suntekstore-img.sfo3.digitaloceanspaces.com/p/32/320d64cb1cdd19d53039f6d85507ecc76c75c29c.jpg"],"thumbnail_link":null,"link":"https://suntekstore.com/p/DCD-10001510378/","markdown_url":"https://suntekstore.com/p/DCD-10001510378.md","json_url":"https://suntekstore.com/products/DCD-10001510378.json","buy_url":"https://suntekstore.com/buy/DCD-10001510378?qty=1","prop65_warning":null}
