GPM Racing Aluminium Rear Adjustable Shock Tower - 14pcs Set for Traxxas 1/10 TRX4 (TRX4030A)

High quality adjustable rear tower for TRX-4 platforms

Engineered as an aftermarket upgrade for the TRAXXAS TRX4 Trail Crawler, this rear shock tower allows controlled variation of shock mounting points to tune rear suspension geometry for crawling. Multiple, evenly spaced mounting holes permit repeatable changes to shock angle and effective stroke without modifying shock bodies.

Constructed from 6061 T6 aluminium to provide stable, lightweight support, the tower increases mount rigidity compared with stock plastic parts. It installs at the rear shock tower location and is adjusted by relocating the shock eye into alternate holes to change leverage and stroke characteristics.

The assembly ships with the twin towers plus the stainless fastening hardware required for installation. On TRX-4 variants not listed below, minor trimming of the rear skid plate may be necessary for clearance.

Compatible Models

• TRAXXAS TRX-4 DEFENDER 82056-4
• TACTICAL UNIT 82066-4

Use this tower for consistent, serviceable adjustments to rear shock geometry when building dedicated crawling setups or when testing incremental changes to handling.

How should I approach tuning with the different holes?

Start with a conservative hole position and evaluate ride height and damping feedback; move the shock eye stepwise to change leverage and note handling differences before finalising hardware torque.

Is the finish suitable for regular trail use?

The 6061 T6 aluminium construction combined with stainless fasteners provides a durable, corrosion resistant assembly appropriate for routine trail and crawling activity. Write Product Review Please sign in your account before you can write any review. Sign In Close
