Traxxas Shock Rebuild Kit Ultra Shocks for 2 Shocks TRX2362

Overview

Keep your Traxxas RC car suspension running smoothly and performing at its best with the Traxxas Rebuild Kit for Ultra Shocks (TRX2362). If you're a serious RC enthusiast in the UK operating Traxxas short course trucks, buggies, and monster trucks, you already know that regular maintenance is the key to consistent performance and durability. The seals inside shock absorbers are consumable parts that require periodic replacement, especially when you're pushing your RC car UK machines hard on dusty terrain or rough surfaces. This rebuild kit contains all the essential components needed to restore two of your Ultra Shocks to like-new condition, ensuring your suspension delivers the smooth, responsive performance that made you choose Traxxas in the first place.

The TRX2362 rebuild kit is engineered specifically for Traxxas Ultra Shocks, which are used across the majority of Traxxas vehicle range including the legendary Rustler, Slash, Stampede 2WD and 4WD trucks, as well as the powerful Hoss 4x4 platform. Ultra Shocks are renowned for their premium construction featuring X-ring seals and hard-chrome shafts that deliver long-lasting smoothness without the annoying oil leaks that plague inferior shock designs. What makes these shocks particularly attractive to UK RC racers and bashers alike is their convenient dual-cap design and easy-access seals, which means rebuilding them is straightforward and doesn't require specialist tools or expertise. Whether you're maintaining your ready-to-run RC truck from the track or the bash spot, this rebuild kit ensures your suspension remains in top condition.

Shock seal degradation is inevitable with use, but the exact service interval depends on your driving environment. Shocks used on harsh terrain with dusty, gritty surfaces will wear seals out far more rapidly than shocks operating on smoother, cleaner conditions. Regular inspection is your best guide to knowing when a rebuild is needed. If you notice excessive oil leakage where the shaft exits the body, visible oil drips on your model, scored or bent shafts, or if the shocks feel rough and lumpy when compressed, it's time for a rebuild. Professional RC users recommend rebuilding all four shocks together even if only one or two appear damaged, as this ensures all shocks operate equally well and deliver balanced suspension performance.

Key Features

• Premium X-ring seals — The rebuild kit includes high-quality silicone X-ring seals that provide superior sealing performance compared to standard O-rings, significantly reducing the risk of oil leakage and extending the service life of your shocks between rebuilds.
• Low-friction white spacers — Fresh spacers included in the kit help maintain proper seal positioning and reduce internal friction, contributing to smooth shock operation and consistent damping performance across the full range of suspension travel.
• Rubber diaphragms — New diaphragms are included to replace worn originals that may have degraded or become brittle, ensuring proper air pressure regulation inside the shock body and maintaining correct rebound characteristics.
• E-clips and C-clips — The kit includes all necessary clips to secure components during reassembly, with C-clips suitable for Big Bore shock compatibility and e-clips for Ultra Shock applications.
• Compatible with Ultra and Big Bore shocks — This single rebuild kit works with both Ultra Shocks and Big Bore shocks, making it a versatile choice for users with multiple shock types across their Traxxas fleet.
• Covers two shocks — The TRX2362 provides complete rebuild components for a pair of shocks, allowing you to service the front or rear suspension in a single operation.
• Dual-cap design — Ultra Shocks feature a convenient two-cap system that makes disassembly and reassembly simple, allowing you to access seals quickly without requiring advanced mechanical knowledge.
• Hard-chrome shock shafts — The original shafts in Ultra Shocks feature premium hard-chrome plating that resists corrosion and scoring, maintaining a smooth finish that prevents oil weeping and ensures long service life.
• Easy maintenance — Thanks to the straightforward design of Ultra Shocks and the comprehensive rebuild instructions provided by Traxxas, this is a task that intermediate RC users can complete in their own workshop without specialist equipment.

Technical Performance

The Traxxas TRX2362 rebuild kit is engineered to exacting standards using quality materials that ensure your shocks operate smoothly and reliably across all driving conditions. The premium silicone X-ring seals employed in this kit are specifically designed for oil retention and long-term durability, providing superior performance to basic rubber seals. Each kit includes replacement seals, spacers, rubber diaphragms, e-clips, and C-clips—all the consumable components that degrade with use. The hard-chrome shafts used in Ultra Shocks are finished to an exceptionally high standard, delivering a smooth surface that minimises friction and prevents oil migration past the seals. The dual-cap design of Ultra Shocks allows simple access to the lower seal assembly, enabling complete seal replacement without requiring the shock to be disassembled beyond the basic level. When properly rebuilt and filled with appropriate shock oil (Traxxas recommend 30-weight silicone shock oil, available separately), these shocks will deliver the responsive, smooth damping that serious RC competitors and weekend bashers expect. The rebuild process involves emptying old oil, replacing seals and diaphragms, and refilling with fresh fluid—a procedure that most intermediate RC users can complete in under an hour per pair of shocks. Proper filling technique is essential; the manufacturer provides detailed step-by-step guidance including air bubble removal and rebound checking to ensure peak performance after rebuild.

Frequently Asked Questions

• How do I know when my Traxxas Ultra Shocks need rebuilding? — You should rebuild your shocks if you notice any of the following warning signs: excessive oil leakage where the shock shaft exits the body, visible oil drips or wet areas on the shock exterior, the shock shaft appears scored, scratched, or bent, or the shocks feel rough, lumpy, or otherwise not-smooth when you compress them with the spring removed. Regular inspection is the best practice, and it's worth rebuilding all four shocks together even if only one or two appear damaged, ensuring balanced suspension performance across your RC truck or buggy.
• Can this rebuild kit work with Big Bore shocks as well as Ultra Shocks? — Yes, the TRX2362 is specifically engineered to work with both Ultra Shocks and Big Bore shocks. The kit includes both e-clips and C-clips, allowing compatibility with both shock types. The clear spacers included in the kit are suitable for Big Bore applications, making this a versatile rebuild solution for Traxxas users with mixed shock types in their fleet.
• What tools do I need to rebuild my shocks with this kit? — You'll need basic hobby tools including a 2.5 mm hex wrench or driver, a 2.0 mm hex wrench or driver, a number 2 Phillips screwdriver (on some models), and side cutters or slip-joint pliers to hold the shock shaft during disassembly. Paper towels, a disposable cup for draining old oil, and optionally latex or nitrile gloves are also recommended. You'll also need shock oil (30-weight silicone is recommended) which must be purchased separately.
• How much shock oil does this rebuild require? — The exact volume depends on your specific shock model, but the Traxxas rebuild guide recommends filling the shock until it is approximately 3mm below the top of the body initially, then cycling the shaft to release air bubbles, and finally topping up to approximately 1.5mm from the top before installing the diaphragm. Traxxas 30-weight silicone shock oil is recommended, though other quality shock fluids of similar viscosity can be used.
• Is shock rebuilding a task suitable for beginners? — Rebuilding Ultra Shocks is definitely achievable for intermediate RC enthusiasts with basic mechanical skills. Traxxas provides comprehensive step-by-step instructions, and the dual-cap design of Ultra Shocks makes the process relatively straightforward compared to more complex shock designs. However, beginners should take their time, follow the instructions carefully, and pay particular attention to proper oil filling and air bubble removal to ensure optimal performance after rebuild.
• How often should I rebuild my shocks? — There is no fixed service interval as seal wear depends entirely on your usage environment. Shocks operating on harsh, dusty terrain will require more frequent rebuilds than shocks used on smooth surfaces. Regular inspection is the best approach—if you notice oil leakage, rough feel, or visible shaft damage, it's time to rebuild. Professional recommendations suggest rebuilding all four shocks together to maintain balanced suspension performance.
• Can I upgrade my shock components while rebuilding? — Yes, while not included in the standard TRX2362 kit, Traxxas offers optional upgrades such as titanium-nitride coated hardened steel shafts (which reduce friction and extend wear life), replacement spring retainers and pistons sets, and upgraded shock caps with hollow balls that provide greater freedom of movement and resist popping off in crashes. These upgrades can be purchased separately and incorporated during the rebuild process.
• What's the difference between 2-hole and 3-hole shock pistons? — While not included in this rebuild kit, Traxxas offers different piston configurations. The 2-hole piston provides more dampening resistance, while the 3-hole piston offers less resistance and a softer feel. The standard configuration for your model is likely correct, but if you find your shocks feel too stiff or too soft after rebuild, experimenting with different piston hole counts can help tune your suspension to suit your driving style and terrain.
