AS91898

Overview

The Team Associated B6.3 FT Steel Bulkhead (AS91898) is an essential tuning component for serious RC enthusiasts running 1/10 scale Team Associated buggies and trucks. This precision-engineered steel bulkhead is designed to provide fine-tuned control over your vehicle's front chassis kick-up angle, one of the most critical suspension geometry settings in competitive RC racing. Whether you're setting up an RC10B6.3, RC10B6.4, RC10T6 series, or RC10SC6 series vehicle, this component gives you the flexibility to dial in the exact kick-up angle your specific track conditions and driving style demand.

The factory Team Associated bulkhead allows you to switch between two distinct kick-up angles simply by reversing the part's orientation—no need to purchase multiple components. This makes it an excellent choice for UK RC car enthusiasts who race at different venues or who want to experiment with suspension geometry without a huge parts investment. Whether you're a competition racer fine-tuning your setup or an experienced hobbyist looking to maximise your vehicle's handling characteristics, this steel bulkhead is built to the exacting standards Team Associated is renowned for, ensuring durability and consistency lap after lap.

As an authorised retailer of Team Associated products, RC Model Shop stocks this popular upgrade component in the UK, ready to help your RC buggy or truck perform at its absolute best. This is one of those fundamental tuning parts that separates a well-dialled-in race machine from a standard setup, making it an invaluable addition to any serious RC racer's spares box.

Key Features

• Dual Angle Design — The bulkhead features a clever dual-sided design with -2.5° and +2.5° offset positions marked clearly on the part, allowing you to achieve either 25° or 30° of kick-up on B6-B6.3 chassis by simply installing it in different orientations, eliminating the need to purchase separate components for different setups.
• Steel Construction — Manufactured from hardened steel rather than aluminium, this bulkhead offers superior durability and rigidity for high-impact racing, resisting wear and deformation that can occur with softer materials during aggressive driving or crashes.
• Precision Geometry Tuning — Kick-up angle is one of the most important suspension parameters affecting your vehicle's turn-in response, mid-corner stability, and overall handling balance, and this bulkhead lets you fine-tune this critical setting without replacing the entire front end.
• Wide Vehicle Compatibility — This single part fits across multiple Team Associated platforms including the RC10B6 series (B6.1, B6.1D, B6.1DL, B6.2, B6.2D, B6.3, B6.3D), RC10B6.4 series (B6.4, B6.4D), RC10T6 series (T6.1, T6.2, T6.4), and RC10SC6 series (SC6.1, SC6.2, SC6.4), giving you maximum value across multiple vehicles.
• Updated Labelling — The part now features updated markings showing +2.5 DEG and -2.5 DEG text instead of the older 30DEG and 25DEG designations, making it crystal clear which orientation provides which kick-up angle and reducing setup confusion.
• B6.4 Compatibility with Offset Angles — For owners of the newer B6.4 chassis which features a different 22.5° factory kick-up angle, this same bulkhead provides 20° and 25° settings, extending its usefulness across the entire B6 platform evolution.
• Factory Team Racing Specification — This is genuine Team Associated Factory Team equipment, the same component used by professional RC racing competitors, ensuring you're using proven, competition-grade components in your RC vehicle.

Technical Performance

This steel bulkhead is engineered with precision-machined tolerances to ensure consistent, repeatable mounting and alignment with your chassis. The material choice of hardened steel is particularly important in this application because the bulkhead experiences significant loads during cornering, braking, and impact events. Aluminium alternatives would flex and deform under the extreme forces generated by a competitive RC buggy or truck, but the steel construction maintains rigid geometry throughout your racing session. The dual-angle design reflects Team Associated's philosophy of providing maximum tuning flexibility—chassis kick-up directly affects how the front suspension geometry changes as the suspension articulates, which in turn influences anti-squat characteristics, turn-in response, and stability in high-speed cornering. For B6 and B6.3 chassis featuring the standard 27.5° factory kick-up, installing this bulkhead with the -2.5° side forward reduces the angle to 25°, while flipping it to use the +2.5° side increases kick-up to 30°. This seemingly small range of adjustment (25° to 30°) can make a substantial difference in how your RC10B6.3 or RC10T6 vehicle handles on tight, technical tracks versus high-speed, flowing courses. The updated labelling system (+2.5 DEG / -2.5 DEG) eliminates ambiguity during setup, a critical consideration when you're testing multiple configurations to find your ideal tune. For owners of the B6.4 generation chassis, the bulkhead adapts to the revised 22.5° baseline, yielding 20° or 25° settings—again, providing the tuning range needed for competitive racing without purchasing additional parts.

Frequently Asked Questions

• What is chassis kick-up and why does it matter on my RC buggy? — Kick-up (sometimes called caster) is the forward tilt of your vehicle's steering axis when viewed from the side. Increasing kick-up angle makes the front suspension geometry more aggressive, improving turn-in response and mid-corner stability, whilst reducing kick-up makes the vehicle feel looser and more forgiving on bumpy tracks. This bulkhead lets you adjust between 25° and 30° to find the sweet spot for your driving style and track conditions.
• How do I know which angle to use on my RC10B6.3? — Start with the factory angle (27.5° is the baseline) and then use this bulkhead to test both 25° and 30° in a practice session. Most drivers find 25° works better on tight, technical tracks, whilst 30° suits faster, flowing courses. Write down which angle works best for your local track, then keep that setting for competitive racing.
• Is this bulkhead compatible with my RC10B6.2 or RC10B6.4? — Yes, this bulkhead is compatible with RC10B6.1, B6.1D, B6.1DL, B6.2, B6.2D, B6.3, B6.3D, B6.4, and B6.4D chassis. However, note that B6.4 owners will achieve different absolute angles (20° and 25°) due to the different factory baseline, but the same part works across all these models.
• Why is steel better than aluminium for this application? — The bulkhead experiences significant bending and torsional forces during racing. Steel maintains its rigid geometry much better than aluminium, which can flex and deform under extreme loads, altering your carefully dialled-in suspension geometry. Using steel ensures consistency and prevents unwanted changes to your kick-up angle mid-race.
• Do I need any special tools to install this bulkhead? — Installation requires basic RC maintenance tools (screwdrivers, possibly an Allen key depending on your specific model variant) and familiarity with your chassis. If you're unsure about the process, refer to your Team Associated build manual or contact our team at RC Model Shop for guidance.
• Can I use this part if I'm a beginner to RC racing? — Whilst this is a tuning component rather than a must-have upgrade for absolute beginners, understanding suspension geometry like kick-up is important for any RC racer wanting to improve performance. If you're serious about learning to tune your RC car UK properly, this bulkhead is an excellent educational investment that will teach you how suspension geometry affects handling.
