Team Associated RC8T4.2 Team Kit – 1:8 4WD Nitro Truggy #80957

The RC8T4.2 is a Team Kit competition model that requires assembly. The nitro engine, electronics, body, wheels and tyres are selected separately, allowing racers to build the car specifically for their preferred equipment, track conditions and racing class.

With extensive adjustment of suspension geometry, differentials, chassis flex and steering characteristics, the RC8T4.2 is designed for racers looking for a professional-level 1:8 nitro truggy platform.

Height-Adjustable Gearboxes

One of the most important new tuning features on the RC8T4.2 is the ability to adjust the height of the front and rear gearboxes.

Changing the gearbox position affects driveshaft angle, suspension geometry and the way the chassis reacts under different track conditions.

Together with the new shock towers, this gives racers another valuable setup option for fine-tuning traction, handling and overall chassis balance.

New 16° KPI Steering Geometry

The RC8T4.2 features new 16° KPI steering blocks together with revised bump steer geometry.

KPI, or King Pin Inclination, influences how the front wheel moves during steering and therefore affects the way the car behaves on corner entry, through the middle of the corner and on exit.

The revised geometry gives racers more precise control over front-end response and steering characteristics.

New and Stronger Suspension Arms

The RC8T4.2 uses newly designed composite front and rear suspension arms.

The updated design focuses on:

• Improved durability
• Revised geometry
• Better compatibility with the updated suspension system
• Increased reliability under demanding 1:8 truggy racing conditions

1:8 truggy racing places extremely high loads on suspension components, particularly on rough tracks and large jumps, making durability a major part of the design.

4 mm Shorter Nitro Chassis

The nitro RC8T4.2 features a 4 mm shorter chassis compared with its predecessor.

The shorter chassis changes weight distribution and vehicle rotation while working together with the revised chassis brace system.

Chassis flex is an important setup tool in 1:8 racing. Different flex characteristics can provide more traction on low-grip or rough tracks, while a stiffer setup can improve precision on smoother, higher-grip surfaces.

Revised Rear Anti-Roll Bar

The RC8T4.2 rear anti-roll bar uses wider mounting points.

The anti-roll bar controls chassis roll and influences rear suspension behaviour during cornering. The revised geometry is designed to provide more consistent and predictable anti-roll bar operation.

Heavy-Duty 40/9 Drivetrain

The RC8T4.2 uses Team Associated’s heavy-duty 40/9 ring and pinion gears.

The larger, stronger gear teeth provide increased tooth engagement and are designed to withstand the high loads generated by modern 1:8 truggy racing.

The drivetrain also features 131 mm universal drive shafts and 17 mm differential outdrives, creating a durable transmission system capable of handling powerful competition nitro engines.

High-Volume Centre Differential

The RC8T4.2 features a high-volume centre differential, providing increased oil capacity to help maintain more consistent differential performance during long races and finals.

Differential oils and internal gear configurations are important setup tools in 1:8 racing, allowing racers to fine-tune power distribution between the front and rear of the car.

Both 19 mm and 20 mm HTC internal differential gear sets are included, providing additional tuning options.

Adjustable Competition Shocks

The RC8T4.2 shocks can be configured using either:

• Bladder setup
• Emulsion setup

The kit includes the necessary components for both configurations together with Factory Team hard-anodized aluminium shock bushings.

This allows racers to tune shock response and suspension feel for different track surfaces, jump profiles and driving styles.

Updated Nitro Truggy Braking System

The RC8T4.2 nitro version features revised:

• Brake pad material
• Brake spring

Consistent braking performance is especially important in 1:8 nitro truggy racing, where long finals and high vehicle weight place significant demands on the braking system.
