Overview
The Pro-Line 1/5 Ultra Reservoir Shock Cap Rebuild Kit (G-PRO6293-01) is an essential maintenance component for owners of the Traxxas X-Maxx monster truck who have invested in Pro-Line's Ultra Reservoir Shock Caps. This rebuild kit contains all the replacement O-rings you need to restore your shock caps to factory-fresh condition, ensuring optimal performance and longevity of your RC suspension system. Whether you're a competitive RC racer in the UK or a weekend basher who pushes your X-Maxx to its limits, regular maintenance of your shock caps is crucial for consistent handling and performance on the track or trail.
Pro-Line's Ultra Reservoir Shock Caps have revolutionised the way X-Maxx owners can upgrade their suspension, transforming stock shocks into fully functional reservoir shocks with superior damping characteristics. However, like all precision RC components, the sealing O-rings in these shocks will eventually wear and require replacement to maintain the integrity of the system. This rebuild kit takes the guesswork out of shock maintenance by providing genuine factory replacement O-rings that are identical to those included with the original Ultra Reservoir Shock Caps, ensuring perfect compatibility and performance.
If you own a ready-to-run RC monster truck like the Traxxas X-Maxx and have upgraded to Pro-Line's Ultra Reservoir Shock Caps, this rebuild kit is an absolute must-have for your spares box. Regular maintenance extends the life of your suspension components, prevents oil leakage, and keeps your shocks performing at their best whether you're running on grass, tarmac, or rocky terrain.
Key Features
- Factory-Specification O-Rings — This rebuild kit contains all the O-rings you need to completely rebuild your Ultra Reservoir Shock Caps, using the exact same factory specifications that Pro-Line includes with new shock caps, ensuring perfect compatibility and performance.
- Complete Rebuild Solution — Unlike purchasing individual O-rings from various suppliers, this kit brings together every O-ring size and type required for a full shock cap rebuild, saving you time and ensuring you don't miss any components.
- Restore to Like-New Condition — Over time, O-rings degrade, harden, and lose their elasticity, causing shock fluid to leak and performance to suffer; this kit allows you to restore your shocks to their original factory performance.
- Prevents Shock Fluid Leakage — Worn O-rings are the primary cause of oil loss in RC shocks; replacing them immediately stops leakage and maintains the proper oil volume necessary for consistent shock damping and performance.
- Maintains Shock Consistency — The Ultra Reservoir Shock Caps work by providing increased oil volume for cooler shock temperatures and improved consistency; fresh O-rings are essential for the system to function as designed.
- Cost-Effective Maintenance — Rather than purchasing new shock caps when O-rings wear out, this affordable rebuild kit allows you to extend the life of your existing components indefinitely.
- Professional-Grade Components — Pro-Line manufactures these O-rings to the same exacting standards as the shock caps themselves, ensuring reliability and durability even under the demanding conditions of high-speed RC bashing.
Technical Performance
The Pro-Line Ultra Reservoir Shock Cap system represents a significant engineering advancement for 1/5 scale RC vehicles, particularly the Traxxas X-Maxx. The stock X-Maxx shock bodies are excellent, but they lack the oil capacity and reservoir design of full-scale vehicle shocks. Pro-Line's solution involves adding an external reservoir to the shock cap assembly, which dramatically increases the volume of shock oil. This larger oil volume accomplishes two critical things: it allows the shock fluid to dissipate heat more effectively (keeping shocks cooler during extended running sessions) and it provides better shock consistency across varying track and weather conditions. The reservoir piston design compensates for the volume of the shock shaft, meaning as the shaft compresses into the shock body, the piston adjusts to maintain consistent pressure and fluid dynamics. The result is noticeably plush performance over small bumps combined with reliable support during massive jumps and landings — just like the shock systems found on full-scale monster trucks and trophy trucks. All internal and external components, including the shock cap, reservoir, piston, and bottom cap, are precision CNC machined from high-grade aluminium to tolerances that match the enormous forces generated by an X-Maxx running 8S LiPo power. The O-rings included in this rebuild kit are the critical sealing components that allow these aluminium assemblies to contain the shock oil without leakage. As these elastomer seals age, they naturally harden and shrink, losing their ability to create a watertight seal; replacement with fresh factory-specification O-rings restores the system to its original performance envelope and prevents the gradual performance degradation that occurs with worn seals.

Frequently Asked Questions
- How do I know if my Ultra Reservoir Shock Caps need rebuilding? — If you notice shock fluid leaking around the shock cap seams, see reduced performance consistency, or observe that your shocks aren't absorbing impacts as effectively as they once did, it's time to rebuild the O-rings. Even if you don't see obvious leakage, many users rebuild their shocks annually as part of regular maintenance, especially if they run frequently or in dusty conditions.
- Is this rebuild kit suitable for beginners? — Shock cap rebuild is an intermediate-level maintenance task that requires some mechanical aptitude and patience, but it's certainly achievable for anyone with basic RC hobby experience. You'll need a clean workspace, possibly a small set of tools for disassembly, and care in handling the precision-machined aluminium components. Many RC enthusiasts in the UK perform this maintenance themselves as part of regular upkeep of their vehicles.
- Will this kit fit my X-Maxx shocks? — This rebuild kit is specifically designed for Pro-Line's 6293 Ultra Reservoir Shock Caps, which fit directly onto stock Traxxas X-Maxx shock bodies. Confirm that you have the Pro-Line Ultra Reservoir Shock Caps (model G-PRO6293-00) before ordering this rebuild kit.
- How often should I rebuild my shock caps? — The frequency of rebuilds depends on your usage. Competitive racers might rebuild annually or even more frequently, whilst casual weekend bashers might go two years between rebuilds. If you run in dusty or sandy conditions, more frequent rebuilds are advisable as contamination accelerates O-ring degradation.
- What tools will I need to rebuild the shocks? — At minimum, you'll need small screwdrivers and possibly a shock rebuild stand or suitable work surface. Some users find it helpful to have a small parts tray to keep O-rings and small hardware organised during the rebuild process. Pro-Line's shock caps are designed for field maintenance, so specialised tools aren't required.
- Can I reuse the old O-rings or do I need to replace them all? — For optimal performance and to prevent future leaks, it's best practice to replace all O-rings with fresh ones from this kit. Old O-rings have lost their elasticity and shape retention, and reusing them defeats the purpose of a rebuild and will likely result in continued leakage.
