Designed to add low mounted weight to compatible Traxxas TRX-4 crawlers, these brass portal covers help improve weight distribution and tire contact during crawling. The heavy brass construction adds a total of 118g of weight directly at the portal axles, keeping the added mass low on the vehicle. This can help improve stability on steep climbs, uneven terrain, and off camber obstacles. The covers are designed as a direct fit for the TRX-4 and replace the compatible factory portal covers. Two brass covers and four mounting screws are included.
• Traxxas TRX-4 Compatible: Designed specifically for the Traxxas TRX-4 portal axle system. They are made to fit the compatible factory portal housing locations.
• Brass Construction: Made from solid brass for increased weight and durability. The metal construction provides a substantial upgrade over lightweight plastic components.
• 118g Added Weight: The pair adds approximately 118g of low mounted weight to the vehicle. Placing weight near the axles can help improve tire contact and overall crawling stability.
• Low Center of Gravity: The added weight is positioned low on the vehicle rather than higher in the chassis. This can help reduce the tendency to tip or roll when navigating steep and uneven terrain.
• Front or Rear Application: The covers can be installed on compatible front or rear portal locations. This gives you flexibility when deciding where additional axle weight is most useful.
• Direct Fit Design: Designed to fit the compatible TRX-4 portal housing without requiring major chassis modifications. They are listed as fitting Traxxas part #8251.
• Complete Two Piece Set: Includes two brass portal covers and four mounting screws. The pair provides a convenient way to add matching weight to a compatible axle assembly.
