Aluminum center gear box for TRX4

This aluminum center gear box is an RC-scale replacement part produced for the TRAXXAS TRX4 Trail Crawler platform, designed to hold and stabilize the center transmission gears for smoother steering response and more consistent crawling performance. The component focuses on securing gear alignment and reducing play in the driveline without changing gear ratios.

The part is intended for hobby-level maintenance and tuning: it serves as a durable mounting point for the center gears, helps maintain consistent gear mesh under load, and supports repeatable setup when adjusting suspension or motor position. When replacing the stock plastic carrier, verify gear mesh and clearance during installation to avoid premature wear.

Included hardware listed with the product from the manufacturer: Stainless Steel Round Head Screw 3x10 - 1pc, Stainless Steel Round Head Screw 3x8 - 3pcs, Stainless Steel Cap Head Screw 2.5x6 - 8pcs, Stainless Steel Flat Head Screw 3x8 - 2pcs. Use the supplied screws to secure the unit and retain any existing bearings or spacers from your original assembly where applicable.
