Traxxas 1/10 TRX-4 owners, bring your rig’s center of gravity lower and add some eye-catching color with Integy’s Billet Alloy Portal Inner Housings. Made from Billet alloy, these pieces replace the inner housing of the portal gearbox (Traxxas OEM part #8252), adding color and weight down low for a lower CG and better traction. Sold in pairs (enough for one vehicle).

NOTE: If you do not know how to assemble or install this product, please ask your local dealer for assistance. All products require some prep out of the package – some components are assembled for packaging purposes only, so we strongly recommend that you check all metal-to-metal fasteners for tightness, check fitment and adjust if needed, and use liquid threadlock where applicable. Failure to do so is not a warranty-related incident.

Extra hardware, shims, or spacers may be required for some installations. Some parts may require permanent modification to the vehicle for fitment, and may eliminate certain OEM features. Items that are different from the OEM part (such as our snow & sand conversions, piggyback shocks, EXT suspension, or extended wheel hubs) may require modification to the vehicle for proper clearance. Some Integy-branded items may be only compatible with the vehicle’s OEM parts but not with another Integy-branded item due to design limitations. For multiple-fitment items, some parts may not be used based on application.
