GPM Racing Aluminium 7075-T6 Rear Trailing Arm Lower Links for Traxxas 1/7 Unlimited Desert Racer-85076-4 (UDR014N)

Precision 7075-T6 rear lower trailing links

This rear lower trailing arm link set is engineered for the TRAXXAS Unlimited Desert Racer PRO-SCALE 4X4 platform. CNC machined from 7075-T6 aluminium with a hollow profile, the components reduce unsprung mass while maintaining high rigidity and a clean metallic finish. The links are intended to improve rear chassis support and stabilise damper mounting, with multiple damper positions to precisely adjust shock angle and tune rear geometry.

Installation uses direct replacement of the factory rear lower trailing links. Fit the dampers into the selected mounting hole to alter damper rake and observe any required shock length or rebound adjustments afterwards. Supplied fasteners correspond to the original hardware dimensions listed in the packing. These are performance upgrade parts for model chassis tuning and handling adjustment only.

Packing includes

• Rear trailing arm lower links - 2pcs
• Cap head screws 4x16 - 4pcs
• 3mm lock nuts - 4pcs

Compatible Models

• TRAXXAS-1/7 UNLIMITED DESERT RACER PRO-SCALE 4X4-85076-4

Use these CNC machined links to refine rear shock geometry and handling characteristics; adjustments will alter chassis behaviour and are intended for model competition and hobby tuning.

Is this part compatible with the specified TRAXXAS chassis?

Yes, UDR014N is produced to match the TRAXXAS-1/7 UNLIMITED DESERT RACER PRO-SCALE 4X4-85076-4 mounting pattern and dimensions listed in the compatibility box.

What mechanical benefits does 7075-T6 provide here?

7075-T6 offers superior yield strength versus common alloys; combined with hollow CNC machining it reduces weight without compromising local stiffness where load is transmitted.

Will the included hardware fit without modification?

Yes, the supplied 4x16 cap head screws and 3mm lock nuts are sized for direct replacement of the stock hardware as listed in Packing includes; check thread engagement during installation.

Should I check shock geometry after fitting?

Yes, changing damper mounting points alters shock angle and effective leverage. Verify shock stroke and adjust preload or damping as required to retain the intended suspension travel and balance. Write Product Review Please sign in your account before you can write any review. Sign In Close
