Key Features

• Octalock Octagon Profile Design — The distinctive octagon shape of this spur gear represents a fundamental advancement in drivetrain geometry, allowing for more precise engagement between the gear and motor pinion and reducing the stress concentration that occurs with traditional designs, resulting in longer component lifespan and more efficient power delivery.
• Eight Locking Tabs Per Pad — Each matching motor pinion features eight purpose-designed locking tabs that engage directly with the spur gear's octagon profile, creating multiple positive contact points that eliminate slipping, prevent gear skipping under acceleration, and ensure consistent drive characteristics throughout the life of the component.
• 75-Tooth Specification — The 75-tooth count is precisely engineered to deliver optimal gear ratios when paired with standard 22-tooth and 24-tooth motor pinions, providing the acceleration and top-speed balance that competitive 1/10 buggy racing demands without sacrificing either low-end torque or high-end efficiency.
• 48 Pitch Specification — The 48 pitch (48 teeth per inch of diameter) ensures perfect meshing compatibility with industry-standard 48 pitch motor pinions used across all modern Team Associated buggies, guaranteeing smooth engagement and minimal gear noise during operation.
• Direct AS91810 Replacement — This gear is engineered as a direct replacement for the earlier AS91810 model, featuring improved octagon geometry whilst maintaining perfect fitment in existing RC10 buggy platforms, making upgrading your existing buggy simple and straightforward.
• Genuine Team Associated Component — Manufactured to exacting OEM specifications at Team Associated's dedicated production facilities, this part carries the full confidence of the manufacturer and integrates seamlessly with all compatible drivetrain components in the RC10 family.
• Proven In Racing — The Octalock system was introduced with the RC10B74.1 competition buggy, meaning this technology has been proven in the most demanding racing environments and by professional drivers pushing their equipment to the absolute limit.

Technical Performance

The Team Associated Octalock Spur Gear 75T 48DP delivers exceptional performance across all operating conditions thanks to precision engineering and careful material selection. At 75 teeth and 48 pitch, this gear is optimised for 1/10 scale 4WD buggy racing where repeatability, consistency and durability are paramount. The octagon profile represents a fundamental engineering improvement over traditional circular designs — it distributes engagement forces across eight distinct contact patches rather than two opposing points, reducing stress concentration and allowing the gear to absorb shock loads without damage. When paired with a compatible 22-tooth motor pinion, this gear produces a 3.41:1 final drive ratio; with a 24-tooth pinion it delivers 3.13:1 — both configurations are ideal for competitive buggy racing where acceleration out of corners and top-speed stability are equally important. The eight locking tabs on the matching motor pinion create a mechanical lock that prevents any slipping or backlash during hard acceleration, ensuring consistent throttle response and precise power delivery in every driving condition. Manufacturing tolerances are held to exacting specifications — tooth spacing is consistent to within industry-leading tolerances, and the gear bore is precisely machined to ensure perfect centering on the drivetrain shaft. This precision engineering directly translates to quieter operation, smoother power delivery, and extended component life compared to older designs.

Frequently Asked Questions

• What is the Octalock system and why is it better than traditional spur gears? — The Octalock system uses an octagon-shaped spur gear profile paired with motor pinions featuring eight dedicated locking tabs. This design creates multiple positive engagement points instead of the two contact points found in traditional circular gears, dramatically reducing slipping and backlash whilst distributing mechanical stress across a wider area. This results in longer component life, more consistent power delivery, and quieter operation — all measurable advantages that make the Octalock system the preferred choice for competitive RC buggy racing in the UK and internationally.
• Is this a genuine Team Associated part? — Yes, the AS92294 is a 100% genuine Team Associated component manufactured to original equipment manufacturer (OEM) specifications. It was introduced with the premium RC10B74.1 buggy and represents Team Associated's latest spur gear technology. When you purchase from RC Model Shop, you receive an authentic factory component with full manufacturer backing.
• What buggy models does this gear fit? — The Octalock Spur Gear 75T 48DP is compatible with all modern Team Associated RC10 series buggies, including the RC10B4, RC10B4.1, RC10B4.2, RC10B5, RC10B5M, RC10B6, RC10B6 Club Racer, RC10B6.1, RC10B6.1D, RC10B6.1DL, RC10B6.2, RC10B6.2D, RC10B64, RC10B64 Club Racer, RC10B64D, RC10B6D, RC10B74, and RC10SC6.1. If you own any of these models, this gear will fit perfectly and provide an immediate upgrade in drivetrain performance.
• Can I use this gear as an upgrade on my current buggy, or does it require a complete drivetrain overhaul? — The Octalock Spur Gear 75T 48DP is specifically engineered as a direct replacement for the earlier AS91810 model and requires only a compatible Octalock motor pinion to function. If your buggy currently uses traditional gears, you may need to source a compatible Octalock pinion, but no other drivetrain modifications are necessary. Many Team Associated owners in the UK upgrade to Octalock components as maintenance items, replacing both gear and pinion together for maximum performance improvement.
• What is the difference between this 75T gear and other tooth counts? — The 75-tooth specification is optimised for balanced performance in competitive 4WD buggy racing. A lower tooth count (such as 72T) would provide higher top speed but lower acceleration; a higher tooth count (such as 78T) would improve acceleration but reduce top speed. The 75T is the sweet spot for buggy racing where you need both responsive acceleration and competitive top-end speed. Pair it with a 22-tooth pinion for 3.41:1 ratio (more acceleration) or 24-tooth pinion for 3.13:1 ratio (more top speed).
• Is this suitable for competitive racing? — Absolutely. The Octalock Spur Gear 75T 48DP was specifically designed for racing use and introduced with the RC10B74.1 race buggy.
