GPM Racing Aaluminium Front and Rear Lower Arms - 28pcs Set for Traxxas 1/10 MAXX W/Widemaxx 2.0 Monster Truck-89086-4 (TXMW055FR)

Strong lower arms for dependable pivots

These aluminium lower arms are an RC-scale replacement part designed for the TRAXXAS 1/10 4WD MAXX with WideMaxx configuration. They locate the c-hubs and lower damper mounts to form a stable connection between suspension components and the chassis; the goal is consistent fitment rather than changing suspension geometry.

Forged from 6061-T6 aluminium, the arms deliver a firmer mounting surface than factory plastics while keeping weight reasonable. Delrin collars at pivot points cut play and channel load onto the metal pivot. White Delrin shims for the rear arms address slightly larger clearances found on some trucks. The fixings use a locating pin with a short screw to limit the risk of stripped threaded inserts during maintenance. Multiple damper holes permit stepwise adjustments to shock angle and ride height.

Fitment notes: install supplied stainless pins and washers, ensure collars are correctly seated prior to final torque, and apply shims on the rear arms only when necessary to remove lateral movement. Check damper hole selection against your current setup to maintain intended handling.

An aftermarket aluminium option to reduce pivot play and provide consistent damper mounting for TRAXXAS MAXX vehicles; use the included pins and shims for correct assembly.

Do these arms come with everything needed to fit them?

The package includes the stainless pins, screws, washers and shims required for installation so no extra hardware should be necessary for the standard swap.

What is the main advantage of the Delrin collars?

Delrin collars reduce lateral play at pivots and protect the aluminium bore from point wear, helping to keep pivot alignment consistent over time.

Can I retain my existing shocks when fitting these arms?

Yes. These arms are designed to work with standard shock assemblies; you can keep your current shocks and use the multiple mounting holes to tune positioning.

Are the rear shims always required?

No. Use the white Delrin 4mm shims on the rear arms only if you observe lateral play after initial assembly; they are provided to accommodate varying clearances.

Will fitting these change handling significantly?

The arms aim to preserve the original geometry while improving fitment and repeatability; handling changes should be subtle and mainly related to firmer pivot stiffness and any damper hole adjustments you choose.
