Fastrax 1/8th 15mm Extension Hub Adaptors 17mm Hex RC Car Tuning Parts FAST920

Overview

The Fastrax 1/8th 15mm Extension Hub Adaptors are essential tuning components designed specifically for RC enthusiasts looking to widen the track of their 1/8th scale vehicles. These precision-engineered hub adaptors are the perfect solution for anyone seeking improved handling characteristics, enhanced stability, and a wider stance on their RC car. Whether you're a competitive racer fine-tuning your setup for maximum performance or a weekend basher looking to improve your vehicle's cornering ability, these extension adaptors deliver the results you need. Available at RC Model Shop, these adaptors are compatible with a range of popular 1/8th scale platforms and represent an affordable way to modify your RC vehicle's geometry.

Manufactured by Fastrax, a trusted name in RC performance parts and accessories, these hub adaptors feature 17mm hex compatibility, making them a direct fit for vehicles equipped with standard hex drive wheels. The 15mm extension length provides a meaningful increase to your vehicle's track width, which translates to improved stability during cornering, reduced body roll, and better weight distribution across the tyres. This is particularly valuable for RC car UK enthusiasts who want to maximise their vehicle's performance on challenging terrain or competitive racing surfaces.

These adaptors come supplied with the correct wheel nuts, and it's crucial to note that you must use the wheel nuts supplied with this set, as other brand wheel nuts could be a different pitch thread and may not fit correctly. This attention to detail ensures perfect compatibility and safe operation. Whether you're upgrading a desert racer, off-road buggy, or other 1/8th scale RC vehicle, the Fastrax extension hub adaptors offer exceptional value and proven performance improvement.

Frequently Asked Questions

• What is the difference between 15mm and other extension hub adaptor sizes? — The 15mm length represents a balanced approach to track widening, providing meaningful improvements to cornering stability and weight distribution without excessively changing your vehicle's overall geometry or requiring major suspension modifications. Different extension lengths suit different driving styles and track conditions, making 15mm an excellent general-purpose choice for most 1/8th scale vehicles.
• Which vehicles are these adaptors compatible with? — These extension hub adaptors are designed for 1/8th scale RC vehicles with 17mm hex wheel adaptors. They are confirmed compatible with the FTX DR8 1/8 Desert Racer in both the 6S RTR Blue and Red versions, and are suitable for many other 1/8th scale platforms with matching hex specifications.
• Why must I use the included wheel nuts? — The wheel nuts supplied with this set are precision-manufactured to match the specific thread pitch of these adaptors. Using wheel nuts from other brands could result in incorrect thread pitch, leading to loose wheels during operation or potential wheel detachment, which compromises safety and performance.
• Will these adaptors improve my RC car's handling? — Yes, by increasing track width, these adaptors provide several handling improvements including reduced body roll during cornering, improved traction consistency, better stability at high speeds, and enhanced weight distribution. Most drivers notice an immediate improvement in cornering feel and overall vehicle control when upgrading to wider track geometry.
• Are these suitable for beginners? — Whilst these adaptors are straightforward to install, they are primarily a performance tuning component suited to drivers who are already comfortable with basic maintenance and setup work. Beginners can certainly use them, but they represent an intermediate-level upgrade rather than an essential component for someone just starting their RC journey.
• How much wider will my vehicle become? — These 15mm adaptors extend the track by 15mm on each side, resulting in a total track width increase of 30mm (15mm per side). This is a noticeable modification that improves stability without drastically altering the vehicle's proportions or causing fitment issues with the chassis or body shell.
