Trident Shaft & Triple Bearing Spool Set – SPC2 / Arrma Limitless / Infraction /Felony

Complete Titanium centre drive shaft and spool set including the original, famous Trident front shaft. Suitable for Speed runners, Drag racers and bashers alike!

SUITABLE FOR OUR SPC & SPC2 & F CARBON CHASSIS (Other carbon chassis could be re-drilled to suit, but will not fit stock aluminium)

Support the original innovator – Beware of overpriced copies!

Following several years of speed running at the highest level, we’re excited to release what we feel is the very best center drive shaft set available for Arrma cars

The Pinocchio spool set has taken the fastest speed runners reliably into the 190+mph zone, but vibration and bearing life at these speeds has been a challenge requiring constant maintenance.

This new triple bearing arrangement re-writes the dynamics of the centre drive system. The longest ever spool, carefully optimised, is supported by three bearings eliminating vibration and flex under load. The fantastic Trident ball bearing front shaft is kept with 102mm length, whilst the rear shaft is a super short, also 102mm length (down from 114 /125mm). This very short titanium shaft runs totally smoothly giving bearings an easy life.

We have been testing this arrangement through the 2024 season with fantastic results, running multiple speed run events without requiring any bearing changes.

Our Trident drive cups are now made in lightweight Titanium!

This shaft set is designed to be a drop it fit to our ‘SPC’ and SPC2 type Arrma chassis. It is also designed to match perfectly with our SPC or Servo Mount top deck braces. It will fit other chassis types, and other top deck braces, but extra holes will need to be drilled. 

Options:

Standard Cup types for Arrma 5mm diff pinions

8mm cup option for cars fitted with Hobao 6mm pinion conversion

Includes complete centre drive set:

·         Trident Front shaft assembly (inc spare bearings and screws)

·         Titanium Trident drive cup (5 or 8mm bore)

·         Extra long three bearing Titanium centre spool

·         102mm titanium rear shaft

·         Rear diff input cup (5 or 8mm bore)

·         7075 Aluminium Third Bearing support assembly

The game changing Trident shaft is a must have for high speed running. A standard shaft pin cannot withstand the speed and loads generated at the front cup, resulting in high friction and rapid pin burn out. Trident has been the go-to solution run by the fastest guys in the world – not least our own 224mph car. Every performance Arrma car will benefit. 180mph plus Arrma cars cannot reliably run without the trident!

Our renown titanium dog bone shafts have been proved over and over again to be the most robust solution on the market. These are fully machined shafts with the main diameter tuned to 7mm diameter to optimise weight and fit. Our specially sourced pins are top quality hardened carbon steel, not just stock dowels or poorly hardened parts. A highly developed and long proven product. We’ve never seen a broken one yet!

The spool is supplied with a 7 PIECE spacer set, including 0.5 and 0.2mm shims for a perfect fit on any spur gear

Spares availability:

Modifying your RC from stock condition can result in unexpected results. Operation of modified models must take this into account. Always follow the original manufacturers instructions. Whilst we build our parts to the highest standards we are able, like all rc parts, our parts cannot be guaranteed for performance, strength and durability in every situation or configuration. Do not use your RC in public areas. Do not use your RC where unexpected results could cause injury or damage to property. High Speed RCs require GREAT CARE and a responsible attitude to use safely.
