The new T4 truck borrows the distinctive forward-swept front end and rear-mounted shock configuration featured on the RC10B4 buggy, optimized with the new co-planar steering geometry. This new suspension design provides maximum front-end clearance and minimizes bump-steer while maintaining desired Ackermann angles. Trailing front axle or optional inline steering blocks can be used to adjust steering response. The suspension arm design features a “captured” hinge pin design so that no e-clips are used. The T4 also features a heavy-duty design front hinge-pin brace and bumper for increased durability.

The transmission has also been optimized into an ultra-compact package, and now uses the same 2.6:1 higher torque-capacity differential as the RC10GT. A double-sided slipper assembly (first prototyped by Team Associated in 1989) has been designed with higher torque capacity, easier assembly, and lower rotating mass than comparable double-sided slippers. This provides a finer adjustment range and more efficient slipper operation.
 

The T4 chassis provides a super-low center of gravity by lowering the motor, battery, and shock mounting positions, enabling Associated’s R&D team to design a sleeker, more realistic low-profile body, greatly reducing the large, unaerodynamic “humps” over the rear shocks as seen on older-design trucks. The T4 also comes equipped with strong, dish-style wheels and high-traction Pro-Line tires.  The RC10T4 - Radio Control Car Action Reader's Choice 2004 winner for Electric Truck in 2005!

Features:

 Angled bellcrank steering minimizes bump steer to maintain constant steering angles throughout the full range of suspension travel.

Front shocks are mounted behind the shock towers. All four suspension arms utilize a “captured” hinge pin design that uses no e-clips.

New 2.6:1 laydown transmission now uses the higher torque capacity differential from the RC10GT. Ultra-compact, efficient, low-CG design.

High torque capacity, double-sided slipper provides finer adjustment, easier assembly, and lower rotating mass than comparable double-sided slippers.

Trailing front axle or optional inline steering blocks can be used to tune steering response

The “forward-swept” front end design provides maximum front end ground clearance. Chassis underside is contoured for maximum clearance when cornering, and minimal ground contact area on hard landings.

 Longer CVD dog bones and axles have been designed into the rear suspension to push the T4 out to maximum legal width for more traction.

 Impact-resistant rear motor guard and body mounts. Lower motor, battery, shock and body mounting positions give the T4 a lower CG for higher cornering speeds and greater stability.
