GPM Racing 7075 Alloy Rear Shock Tower for Arrma 1/7 Mojave 6S 4x4 RTR Brushless Desert Truck (MJ3030)

Product overview for MJ3030

The MJ3030 rear shock tower is a replacement component made for ARRMA Mojave 1/7 platforms. It revises the factory rear tower geometry and provides additional mounting positions while maintaining direct fit on the listed Mojave chassis codes. The tower is machined from 7075-T6 aluminium to offer repeatable stiffness and good wear resistance during off-road operation.

Highlights include multiple shock mounting holes to change shock angles and leverage, a robust 3D profile for better structural integrity, and upper mounting holes sized for M4 shock standoffs. Compared with the original tower specified at 5.0mm thickness, the MJ3030 adds material in critical areas to 9.0mm to reduce deformation under load. The part is intended for hobbyist installation on compatible Mojave models and for tuning suspension characteristics and rear-end rigidity.

Installation notes: the tower uses 4mm upper holes for M4 hardware, aligns with the factory shock geometry on compatible Mojave 6S platforms, and replaces the indicated factory rear tower parts where fitment is confirmed. Use standard tools and normal suspension setup practices when installing this alloy tower.

Compatible Models

• ARRMA 1/7 Mojave 6S 4X4 RTR Brushless Desert Truck-ARA7604V3
• ARRMA 1/7 Mojave 6S EXB 4X4 RTR Brushless Desert Truck-ARA7704V3

Install the MJ3030 when extra rear stiffness and additional shock mounting flexibility are desired; always confirm chassis compatibility before finishing the build.

What alloy is used for this tower?

The MJ3030 is CNC-machined from 7075-T6 aluminium to provide increased rigidity and improved wear resistance compared with lower grade alloys.

Which chassis codes are supported?

Supported chassis codes are listed in the compatible models block; those Mojave variants have been used to confirm fitment of the MJ3030.

How does added thickness change durability?

The increased 9.0mm sections reduce local flex and lower the chance of deformation under heavy impacts, improving long term durability for demanding use.

What hardware should I use for fitting?

Use M4 shock standoffs in the 4mm upper holes and standard thread-locking and torque practices for secure installation on Mojave platforms. Write Product Review Please sign in your account before you can write any review. Sign In Close
