Key Features
- Strong and durable steel construction — Manufactured from premium-grade steel, these shock shafts are engineered to withstand extreme impacts, aggressive driving, and challenging terrain without bending or flexing, ensuring consistent performance in all conditions whether you're bashing in the garden, racing on a track, or exploring rocky off-road terrain.
- Precision manufactured threads — The perfectly machined threads allow for quick and easy servicing, meaning you can remove and reinstall your shocks without stripped threads or fitting problems, saving you time and frustration when you need to replace damper fluid, springs, or other internal components.
- Polished shaft finish — The carefully polished surface of each shaft creates a smooth, friction-free operation that delivers plush shock absorber action, reducing harshness and transmitting bumps more smoothly through the suspension for improved ride quality and driver control across all surfaces.
- 3mm diameter precision specification — The exact 3mm diameter is engineered to match ARRMA's exacting tolerances, ensuring perfect fit and compatibility with your shock bodies and ensuring that your suspension geometry and performance remain true to factory specifications.
- 67mm shaft length — This length is specifically designed for ARRMA's popular 1/10 and 1/8 scale models, providing the correct stroke and suspension geometry to maintain balanced handling and consistent damping characteristics across a range of driving speeds and conditions.
- Pair of two shafts included — You receive two shafts in each package, allowing you to service either the front or rear pair of shocks, or keep spares readily available for quick repairs during racing events or intense bashing sessions.
Technical Performance
The ARRMA Shock Shaft 3x67mm represents the engineering excellence that has made ARRMA a trusted name among RC enthusiasts throughout the UK and globally. These shafts are manufactured using high-quality steel that provides the perfect balance between strength and weight, critical factors in suspension performance. The 3mm diameter provides structural rigidity whilst remaining light enough to avoid adding unnecessary unsprung mass that would negatively impact handling. The 67mm length is precisely calculated to work in harmony with ARRMA's shock absorber designs, delivering the correct amount of travel and stroke for optimal suspension compliance. The polished finish isn't merely aesthetic; it significantly reduces friction between the shaft and the shock body's internal seals, which translates into smoother, more responsive shock action. This smoother action is particularly noticeable when driving over bumpy terrain or landing jumps, where the shafts allow the suspension to compress and extend more fluidly rather than binding or sticking. The precision-manufactured threads ensure that when you disassemble your shocks for servicing or damper fluid changes, you won't encounter stripped or damaged threads that would compromise the integrity of your suspension assembly. Whether you're running your vehicle hard on a competitive track or enjoying weekend bashing sessions, these shafts will maintain consistent performance and reliability. The steel construction ensures durability across a wide temperature range, meaning your shocks will perform equally well in summer heat or cooler UK winter conditions.
