Team Associated RC28R 3.5mm Ballstuds M2 x 4mm Replacement Parts Pack AS21646

Overview

The Team Associated RC28R 3.5mm Ballstuds M2 x 4mm represent genuine OEM hardware designed specifically for the Team Associated RC28R 1:28 scale on-road competition platform. These precision-engineered ballstuds are essential replacement components for maintaining your RC car's suspension geometry and steering linkage in optimal working condition. Whether you're a dedicated track racer, a weekend hobbyist, or someone exploring the world of high-performance RC vehicles in the UK, having spare ballstuds on hand is a practical investment in keeping your model in peak racing condition.

The RC28R itself is a purpose-built 2WD electric on-road race car that combines compact dimensions with serious competitive capability. Developed with the same engineering precision found in every AREA 51-developed product, this 1:28 scale machine delivers impressive performance in an easy-to-setup package. The RC28R features advanced suspension design with fixed-arm front suspension, optional molded upper arms for tuning caster and camber, and innovative torsion side links that eliminate the need for conventional side springs whilst enhancing performance across multiple setup parameters. When you're working on such a carefully engineered platform, using genuine OEM replacement parts like these ballstuds ensures you maintain the precision and consistency your model demands.

These 3.5mm ballstuds come in a practical pack of five units, making them ideal for stocking up your spare parts collection or maintaining your RC28R during regular maintenance routines. As an authorised Team Associated dealer in the UK, RC Model Shop supplies only genuine parts that meet the original specifications and quality standards of the manufacturer.

Key Features

• Genuine OEM Hardware — Manufactured by Team Associated and supplied under the official AS21646 part number, these ballstuds are authentic components engineered to exact specifications, ensuring perfect fitment and reliable performance in your RC28R's suspension and steering systems.
• M2 x 4mm Specification — The M2 threaded specification combined with the 4mm length makes these ballstuds the correct size for all RC28R front and rear suspension pivot points, delivering precise geometry and predictable handling characteristics.
• 3.5mm Head Diameter — The 3.5mm ballstud head works in conjunction with compatible ballstud sockets and washers throughout the RC28R's suspension assembly, maintaining proper alignment and allowing smooth articulation of suspension components.
• Pack of Five Units — Each purchase includes five ballstuds, providing excellent value and ensuring you have spares ready for replacement when wear occurs through normal use and maintenance cycles.
• Essential Replacement Part — Ballstuds experience wear through regular track use, practice sessions, and tuning adjustments; having a selection of fresh units on hand means you can maintain your RC28R's precision handling without downtime waiting for replacement parts to arrive.
• Precision Engineering — Like all Team Associated parts, these ballstuds are manufactured to exacting tolerances, ensuring consistent fitment and eliminating the frustration of loose or misaligned suspension components that can compromise your car's on-track performance.

Technical Performance

The RC28R ballstuds represent the kind of precision hardware that underpins the entire philosophy of the RC28R competition platform. With an M2 threaded design and 4mm overall length, these components work with the RC28R's advanced suspension architecture, which includes fixed-arm front suspension with optional molded upper arms for adjustable caster and camber tuning. The torsion side links integrated into the RC28R's design (supplied in soft, medium, and hard options) replace conventional side springs and connect to your chassis using correctly sized ballstuds. The rear pod assembly features adjustable axle heights utilising Factory Team carbon fibre shims, another system that relies on properly sized and conditioned ballstuds for smooth operation. The threaded aluminium centre shock can be tuned for droop and spring collar adjustment, again depending on quality ballstuds for reliable functionality. Even the adjustable servo mount for fine-tuning Ackermann geometry on the fly depends on quality hardware. When operating a precision 1:28 scale 2WD electric on-road car in competitive environments, maintaining all these systems with fresh, genuine replacement parts ensures your setup changes translate into actual on-track improvements rather than being masked by component wear. The steel chassis plate provides a low centre of gravity whilst the insert adjustable roll centre enables chassis roll adjustment based on grip levels — all systems requiring quality ballstuds for optimal tuning range. These M2 x 4mm units are the correct specification for this platform, ensuring that when you adjust your RC car's geometry, it stays exactly where you set it throughout your racing session.

Frequently Asked Questions

• Are these ballstuds compatible with the RC28R Team Kit? — Yes, these M2 x 4mm ballstuds with 3.5mm head diameter are the correct OEM specification for all RC28R suspension and steering pivot points. The RC28R Team Kit features fixed-arm front suspension with upper arm options, torsion side links in multiple stiffness grades, adjustable rear pod designs, and adjustable servo mounts — all systems that utilise these ballstuds as critical connection points.
• What is the difference between these and generic ballstuds? — These are genuine Team Associated OEM parts engineered to the exact specifications required by the RC28R platform. Generic ballstuds may have slightly different head diameters, thread specifications, or material properties that could result in loose fitment or unpredictable suspension behaviour during competition. OEM parts ensure precision and consistency.
• How often do ballstuds need replacing? — Regular track use, aggressive handling, and frequent suspension tuning adjustments will gradually wear ballstuds through normal operation. Keeping spare packs on hand allows you to replace them preventatively before wear affects your car's handling, ensuring you always have the precision geometry your setup requires for competitive racing.
• What other RC28R spare parts does RC Model Shop stock? — As an authorised Team Associated dealer in the UK, RC Model Shop supplies a comprehensive range of RC28R replacement components including centre shock sets, rear pod and axle carrier sets, chassis plates, bearing sets, steering blocks, servo mounts, pivot blocks, and complete bulkhead assemblies. We also stock compatible accessories like pinion gear sets, tyres, wheels, body options, and specialist tools required for assembly and maintenance of your RC28R.
• Can I use ballstuds from other manufacturers? — Whilst other manufacturers produce ballstuds in M2 x 4mm specifications, using genuine Team Associated parts ensures the precision fit and material quality specifically engineered for the RC28R's suspension geometry. Cross-brand substitution may result in fitment inconsistencies or wear patterns that affect your car's handling characteristics and tuning predictability.
