GPM Racing 7075-T6 Alloy Rear Lower Suspension Arms for Tamiya 1/10 Dt-04 RC Fighter Nxgen-58741 (DT4056)

Precision rear lower suspension arm for SAVAGE XS FLUX

This replacement rear lower suspension arm is CNC-machined from 7075-T6 aluminium alloy to provide a high-accuracy aftermarket option for the rear lower suspension location on compatible models. The component is anodized in sky blue, black, or silver and supplied with the appropriate pins and screws to support straightforward installation. Where applicable, hardware is pre-assembled, and the use of medium-strength screw glue on recommended fastenings is advised to maintain assembly integrity during operation.

The 7075-T6 alloy construction is selected for its tensile strength and wear resistance, offering improved resistance to deformation compared with standard plastic arms while helping to preserve suspension geometry under increased loads. Use this arm for restoring damaged factory components, maintaining pivot accuracy, or tuning suspension behaviour. Check clearances and symmetry after fitting as changes in stiffness can alter handling characteristics.

Installation procedure: remove the original rear lower suspension arm and relocate any bearings or inserts as required, align the replacement arm at the factory mounting points, secure using the supplied stainless steel pins and Grade 12.9 black round head screws, and apply medium-strength screw glue to threaded fixings where recommended. Verify unrestricted suspension articulation before initial running.

Engineered as a direct aftermarket rear lower suspension replacement for the listed platforms, this CNC-machined 7075-T6 arm supports durability improvements and incremental tuning adjustments.

Is machining tolerance suitable for precision setups?

Yes, CNC machining to tight tolerances ensures consistent pivot locations and repeatable fitment across replacement units, which is useful for precision setup work.

What maintenance does the alloy arm require?

Inspect mounting holes and pins for wear, keep pivot interfaces clean and lubricated where applicable, and re-tighten fasteners with recommended screw glue as part of routine maintenance.

Can this arm be used in competition setups?

The arm is suitable for serious tuning and durability-focused builds; however, changes in stiffness can affect handling so validate setup on the track before competitive use.

Are replacement hardware items available separately?

Standard stainless steel pins and Grade 12.9 screws are used, and replacements can be sourced from typical RC hardware suppliers if needed. Write Product Review Please sign in your account before you can write any review. Sign In Close
