Key Features
- Black-Anodised Aluminium Construction — The caps are manufactured from premium aluminium that has been black-anodised, providing a combination of lightweight strength and corrosion resistance that ensures these components will withstand the demands of both casual and competitive RC racing on UK terrain.
- Fox Racing Shock Compatibility — These shock caps are specifically engineered to work with Fox Racing shock absorbers, which are recognised as premium suspension components in the RC industry and deliver superior handling characteristics for desert racing and off-road driving.
- Set of Four Caps — This package includes all four shock caps needed to complete a full suspension refresh on your RC vehicle, eliminating the need to purchase multiple single caps and ensuring consistency across all four corners of your truck.
- Professional Finish — The black-anodised coating provides both aesthetic enhancement and functional protection, giving your RC short-course truck a more finished, professional appearance whilst protecting the underlying aluminium from oxidation and wear.
- Genuine Traxxas Engineering — As official Traxxas parts, these shock caps are manufactured to the same rigorous standards as the complete vehicles, ensuring perfect fitment and reliable performance with your UDR or other compatible models.

Technical Performance
The Traxxas Fox Black Aluminium GTR Shock Caps represent a significant step up in suspension component quality for discerning RC enthusiasts. Manufactured from 6061-T6 aluminium alloy and finished with a professional black-anodised coating, these caps combine lightweight construction with exceptional durability. The anodising process creates a hard oxide layer that protects against corrosion, UV damage, and the wear that comes from regular use in muddy, wet, or salty UK environments. Each cap is precision-engineered to work with Fox Racing shock absorbers, which are engineered for high-performance desert racing and demanding off-road conditions. The four-cap set allows you to maintain consistent suspension geometry across your entire vehicle. For RC trucks running brushless motors and competing in short-course racing or casual bashing, quality shock components like these are critical to maintaining responsive handling, proper damping characteristics, and overall vehicle stability. The black finish not only looks professional but also helps with temperature management by reducing heat reflection. Whether you're upgrading from standard plastic caps or replacing worn components on your existing setup, these aluminium caps deliver noticeable improvements in suspension feel and responsiveness. The compatibility with Fox Racing shocks — recognised as premium components throughout the RC racing community — means you're pairing your caps with suspension technology developed for professional-grade performance.

Frequently Asked Questions
- Are these shock caps compatible with my Traxxas UDR? — Yes, these TRX8456 shock caps are specifically designed for Traxxas UDR models equipped with Fox Racing shocks. They are compatible with both the TRX85086-4-FOX1 (UDR with Fox Racing) and TRX85086-4-RGD1 (UDR with Rigid Industries) variants, though they are optimised for the Fox Racing suspension system.
- What makes these better than plastic shock caps? — Aluminium shock caps offer several advantages over plastic alternatives. They're significantly more durable and resistant to cracking or breaking during impacts, they provide better heat dissipation from the shock absorber, they offer superior corrosion resistance — especially important in the UK's varied weather conditions — and they give your RC truck a more professional, finished appearance. The black-anodised finish adds both aesthetics and functional protection.
- Will these fit my Fox Racing shocks? — These caps are engineered specifically to work with Fox Racing shock absorbers, which use a specific design and diameter. They will not fit standard Traxxas shocks or other brands' shocks. Confirm your vehicle is equipped with Fox Racing shocks before purchasing, or verify against the compatible model numbers listed (TRX85086-4-FOX1 or TRX85086-4-RGD1).
- Why would I need to replace my shock caps? — Shock caps can become damaged through normal use — they can crack, fade in colour, or wear from exposure to mud, water, and UV light. Replacing them is a straightforward way to refresh your suspension components, improve durability, and maintain the professional appearance of your RC short-course truck. They're also essential if you're upgrading to Fox Racing shocks for the first time.
- Are these genuine Traxxas parts? — Yes, these are official Traxxas TRX8456 components manufactured by Traxxas. The part number, EAN code (020334845603), and specifications are identical to Traxxas' official listings, guaranteeing genuine quality and perfect fitment with compatible vehicles.
- How difficult is installation? — Shock cap replacement is one of the simplest RC maintenance tasks. The caps simply slide or screw onto the top of your shock absorber body. Most users can complete the installation of all four caps in under five minutes with no special tools required. Refer to your vehicle's manual for specific instructions if needed.
- What is the black-anodised finish? — Black anodising is an electrochemical process that creates a hard oxide coating on the aluminium surface. This coating provides excellent corrosion resistance, makes the parts harder and more scratch-resistant than bare aluminium, and gives the professional black appearance. It's widely used in high-performance RC components because it combines aesthetics with functional durability.
- Can I use these on standard Traxxas shocks? — No, these caps are specifically designed for Fox Racing shocks and are not compatible with standard Traxxas shocks, which use different dimensions and mounting systems. Using incompatible caps could result in poor fitment and suspension issues.
