Hot Racing Aluminum Differential Carrier Case Bottom Cover BLX 3S 4S

This Hot Racing aluminum differential carrier case bottom cover is built for Arrma BLX 3S and 4S vehicles. Aluminum construction protects the differential carrier from impacts and rock strikes far better than the stock plastic cover.

It’s a direct-fit hop-up shared across Arrma’s popular BLX 3S and 4S lineup. Like other Hot Racing hop-up parts, it’s built as an easy bolt-on improvement over stock.

• Aluminum construction for impact protection
• Direct replacement for the factory bottom cover
• Fits Arrma BLX 3S and 4S vehicles
• Protects the differential carrier case
