Team Associated RC8T4.2e Team Kit – 1:8 4WD Electric Truggy #80958

The RC8T4.2e is a Team Kit competition model that requires assembly. The brushless motor, ESC, steering servo, radio system, battery, body, wheels and tyres are selected separately, allowing racers to build the car specifically for their racing class, track conditions and personal preferences.

The RC8T4.2e is designed for racers looking for a professional-level 1:8 electric truggy platform with extensive adjustment possibilities for suspension, differentials, steering geometry and chassis setup.

Height-Adjustable Gearboxes

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

Changing the gearbox position affects driveshaft angles and suspension geometry, giving racers another way to adjust the handling characteristics of the car for different levels of grip and track layouts.

Together with the updated shock towers, this provides additional control over front and rear suspension behaviour.

New 16° KPI Steering Geometry

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

KPI, or King Pin Inclination, influences the movement of the front wheels during steering and therefore affects:

• Corner entry
• Steering response
• Mid-corner behaviour
• Steering feel on corner exit

The revised geometry gives racers more options to fine-tune front-end response and overall steering characteristics.

New Suspension Arms

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

The updated design focuses on:

• Improved durability
• Revised geometry
• Greater reliability
• Updated construction

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

High-Volume Centre Differential

The RC8T4.2e features a high-volume centre differential with increased differential oil capacity.

The additional oil volume helps maintain more consistent differential performance during longer runs, while the centre differential itself is one of the most important setup tools on an electric 1:8 truggy.

By changing differential oil viscosity and internal gear configuration, racers can alter the way power is distributed between the front and rear of the car.

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

Heavy-Duty 40/9 Drivetrain

The RC8T4.2e uses heavy-duty 40/9 ring and pinion gears designed to handle the high loads produced by powerful 1:8 brushless systems.

The drivetrain also features:

• 131 mm universal drive shafts
• 17 mm differential outdrives
• Front, centre and rear differentials

The high torque produced by electric truggy power systems places significant stress on the drivetrain, and the RC8T4.2e transmission is designed specifically with competition use in mind.

Choose Your Own Brushless Power System

The RC8T4.2e Team Kit does not include a motor or ESC.

This allows racers to select their preferred 1:8 brushless power system according to:

• Racing class
• Track size
• Track grip
• Desired power level
• Battery configuration
• Personal driving style

This is one of the main advantages of a competition kit — the complete electronics package can be selected specifically for its intended use.

Adjustable 16 mm Competition Shocks

The RC8T4.2e shock absorbers can be configured as either:

• Bladder setup
• Emulsion setup

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

Shock oil, pistons, springs and shock mounting positions allow racers to precisely adjust suspension behaviour for different tracks and conditions.

Revised Rear Anti-Roll Bar

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

The anti-roll bar controls chassis roll and influences rear suspension behaviour during cornering, making it an important setup tool for changing the balance of the car.

Different anti-roll bar settings can be used to adapt the car to both high- and low-grip tracks.

High-Downforce Rear Wing

The RC8T4.2e includes a high-downforce rear wing designed to improve rear-end stability and traction at higher speeds.

Aerodynamics play an important role in 1:8 truggy racing, particularly on fast tracks, and rear wing setup can influence the balance of the car both through corners and over jumps.
