The Traxxas 2380 Pro-Built differential is a complete, factory-assembled replacement differential for compatible 1/10-scale Traxxas 2WD vehicles fitted with the standard Magnum 272 transmission. Supplied ready to install, it eliminates the need to assemble the internal differential gears individually. It is a practical replacement for a worn, damaged, slipping or rough-running factory differential in compatible Bandit, Rustler, Slash and Stampede models. This differential is designed for the standard Magnum 272 transmission. It does not fit the Magnum 272R transmission used in selected newer or upgraded Traxxas 2WD vehicles. Features Complete Differential Assembly: Supplied with the internal differential components already assembled Pro-Built Construction: Factory assembled to reduce repair and installation time Direct Replacement Part: Designed for compatible Traxxas Magnum 272 transmissions Planetary Gear Design: Replaces the standard geared differential used in the Magnum 272 transmission Compatible with Brushed and Brushless Models: Fits selected XL-5 and VXL versions when equipped with the correct Magnum 272 transmission Restores Differential Operation: Replaces worn gears, damaged outputs or an inconsistent differential assembly Genuine Traxxas Part: Manufactured to match compatible Traxxas transmission dimensions Ready to Install: No internal differential assembly is required before fitting Specifications Brand: Traxxas Manufacturer Part Number: 2380 Product Type: Complete transmission differential assembly Vehicle Position: Rear transmission Drive Configuration: Two-wheel drive Transmission Compatibility: Traxxas Magnum 272 Magnum 272R Compatibility: No Differential Type: Planetary gear differential Assembly Status: Fully assembled Typical Vehicle Scale: 1/10 Quantity: One complete differential assembly Compatibility Compatible with selected Magnum 272-equipped versions of: Traxxas Bandit Traxxas Bandit VXL Traxxas Rustler 2WD Traxxas Rustler VXL 2WD Traxxas Slash 2WD Traxxas Slash VXL 2WD Traxxas Slash 2WD Unassembled Kit Traxxas Stampede 2WD Traxxas Stampede VXL 2WD Traxxas Ford F-150 Raptor 2WD Traxxas BIGFOOT No. 1 Officially Licensed Replica Compatibility depends on the transmission installed in the vehicle. Confirm that the vehicle uses the standard Magnum 272 transmission and lists part 2380 in its exploded diagram before ordering. Includes 1 × Traxxas Pro-Built complete differential assembly Required to Complete Compatible Traxxas vehicle fitted with a Magnum 272 transmission Suitable hand tools for transmission removal and disassembly Traxxas-compatible differential grease if required during installation Replacement transmission gasket, bearings or worn hardware if required FAQ Does Traxxas part 2380 fit the Magnum 272R transmission? No. Part 2380 fits the standard Magnum 272 transmission and is not compatible with the Magnum 272R. How can I tell whether my vehicle has a Magnum 272 or 272R transmission? Check the vehicle model number, transmission housing and exploded parts diagram. The 272R normally has a different housing design, an aluminium motor plate and a sealed, oil-filled differential. Is the differential fully assembled? Yes. The internal differential components are factory assembled and supplied as one complete unit. Are bearings included? The product is supplied as the complete differential assembly. Reuse the existing transmission bearings if they are serviceable or replace them separately when worn. Is this a sealed oil-filled differential? No. The standard Magnum 272 differential is not designed as the sealed, silicone-oil-tuneable differential used in the Magnum 272R. Should differential oil be added to part 2380? No. Do not fill it with silicone differential oil. Service it with the grease specified for the standard Magnum 272 differential and transmission. Does it fit four-wheel-drive Traxxas models? No. Part 2380 is intended for selected 1/10-scale Traxxas two-wheel-drive vehicles using the Magnum 272 transmission. Will it fit both brushed and VXL models? It fits selected brushed and VXL vehicles when they are equipped with the standard Magnum 272 transmission. Some newer or upgraded VXL models may use the Magnum 272R, so the transmission must be confirmed first. What symptoms indicate a worn differential? Common symptoms include clicking, grinding, inconsistent drive, excessive free movement, one wheel receiving little power or visible damage to the internal gears and output components. Does the complete transmission need to be removed? The Magnum 272 transmission normally needs to be removed and opened to access and replace the differential. Should the transmission bearings be checked during installation? Yes. Inspect the differential bearings, idler gears, shafts and transmission case for roughness, looseness or damage before reassembly. Can this differential handle brushless power? It is used in selected compatible VXL applications, but drivetrain life depends on gearing, tyre size, vehicle weight, slipper-clutch adjustment and driving conditions. Important Notes This part fits the standard Traxxas Magnum 272 transmission only. It does not fit the Magnum 272R transmission. Confirm the transmission type using the vehicle model number or exploded parts diagram before ordering. Some vehicles with the same model name may use different transmissions depending on their production version. This is a two-wheel-drive transmission differential and is not intended for Traxxas 4X4 models. The differential is supplied assembled, but transmission removal and disassembly are still required for installation. Do not fill this differential with silicone differential oil. Use only the grease and servicing method recommended for the Magnum 272 transmission. Inspect the differential bearings before reusing them. Replace any damaged gears, shafts, bearings or transmission-case components during installation. Remove dirt and old contaminated grease before reassembling the transmission. Do not over-tighten screws installed into the composite transmission housing. Confirm that the differential rotates smoothly before reinstalling the transmission. Incorrect slipper-clutch adjustment, oversized tyres and aggressive high-power use can increase differential and transmission wear.
