TRAXXAS TRX4 Trail Crawler Aluminum Front Adjustable Shock Tower by GPM TRX4028A  [TRX4028A]

Front adjustable shock tower for TRX4

This front shock tower is an aluminum replacement designed for RC-scale TRX4 trail crawlers to change shock mounting positions and suspension geometry without altering stock shock absorbers. The part is produced in 6061 T6 aluminum to provide a lightweight yet stiff mounting point that resists bending under load.

The tower offers multiple positioning holes so you can vary shock angle and ride height; repositioning the shock top mount lets you tune axle articulation and shock leverage for different trail and crawling conditions. The part stabilizes the shock in each selected hole to keep the damper aligned during steering and suspension travel.

Included hardware from the original source is supplied to fit the tower to the front bulkhead: front shock tower 2pcs, stainless steel round head screw 3x16 2pcs, stainless steel flat head screw 3x10 4pcs, stainless steel round head screw 3x18 2pcs, and 3x6x2 alloy collar 4pcs. Follow standard RC practice when tightening fasteners and verify clearances with steering and skid components before running.

Note on fitment: this tower is listed for TRAXXAS TRX-4 DEFENDER 82056-4 and TACTICAL UNIT 82066-4. For other TRX-4 variants, skid plates or nearby components may require trimming to clear this tower; confirm fit on your chassis before final installation.

Use this aluminum front adjustable shock tower to change shock geometry quickly for climbing or technical trail sections, keeping tuning focused on linkage and spring/damper setup rather than replacing shock assemblies.
