TRAXXAS TRX4 Aluminum Center Gear Box TRX4038 by GPM  [TRX4038]

Aluminum centre carrier for TRX4

This aluminum center gear box is an aftermarket replacement made for the TRAXXAS TRX4 Trail Crawler platform, engineered to secure and stabilise the center transmission gears for more precise steering feel and steadier crawling performance. The part clamps gear alignment and reduces driveline slop while keeping original gear ratios unchanged.

Designed for routine hobby maintenance and tuning, the unit acts as a robust mounting point for the center gears, helping preserve consistent gear mesh under load and allowing repeatable setup when you change suspension or motor position. When fitting this in place of the stock plastic carrier, check gear mesh and clearances carefully to prevent early 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. Fit the supplied screws to mount the unit and keep or replace bearings and spacers from your original assembly where required.

For TRX4 owners chasing a firmer, more repeatable centre transmission mount, this aluminum center gear box is a direct upgrade; confirm correct gear mesh when installing and refresh bearings as needed for best longevity.
