GPM Racing 7075-T6 Alloy Shock Caps for Traxxas 1/7 Unlimited Desert Racer-85076-4 (UDRDP/CAP)

7075-T6 Alloy Shock Cap Upgrade

These aftermarket shock caps are intended for TRAXXAS Unlimited Desert Racer platforms and are built for durability and service convenience. Machined from 7075-T6 aluminium, they replace the factory top caps and are compatible with stock shock bodies and GPM aftermarket shock parts.

Design highlights include integrated bladders to bolster sealing and service life, a bleeder hole for simpler pressure relief and maintenance, and a pivot ball interface to preserve smooth suspension articulation at the damper crown. The set is supplied as a direct replacement using existing mounting points.

Installation procedure: remove the shock from its mount to access the top cap, contain or drain oil prior to opening, swap the factory cap for the alloy cap and install the supplied bladder, then reassemble and inspect for leaks at the bleeder. Basic experience with shock servicing helps ensure correct seal orientation and oil level.

Tuning note: these caps do not alter internal valving but can improve sealing consistency and slightly affect articulation at the top of travel, making damping feel more consistent under repeated use. They are best used as a durability and maintenance upgrade rather than a valving change.

What TRAXXAS models will accept these caps?

See the Compatible Models list above for the exact TRAXXAS models and part numbers supported by the UDRDP/CAP kit. If your model number matches one listed, the caps are designed to fit directly.

Is any special tooling required to fit the caps?

No specialised tooling is required beyond common shock service tools. Remove the shock, manage the oil, replace the top cap and bladder, then refill and verify seal seating and bleeder port integrity.

Will the bleeder hole make routine service quicker?

Yes. The bleeder port simplifies pressure relief and air purging during refill, reducing service time and lowering the risk of air-related damping inconsistency.

Should I expect any change in handling after installation?

The caps do not change internal valving, so handling changes are limited. Improved sealing and the pivot ball interface can improve consistency and articulation, resulting in a more repeatable shock response rather than a tuning overhaul.
