Team Associated engineers focused on lowering the center of gravity and weight, and improving handling on loamy outdoor tracks.

The heart of the buggy is the new RWB/FWB adjustable weight distribution chassis. This innovative system allows the driver to ride in either configuration with the motor to the rear for more traction, or to move the center differential and reverse the center driveshafts to turn the engine forward for more steering.

The suspension has been redesigned with new low-CG front and rear shock towers and shorter shock absorbers, as well as new 3-hole rear suspension arms that soften the dampers and springs while maintaining good support in fast corners.

The new wide-base rear hubs are available in three fixed axle heights and use 3 mm carbon-fibre hub towers to allow several different geometry options.

Finally, the buggy is equipped with 92 mm universal driveshafts, 44/13 bevel gears and a molded plastic center ring gear for improved grip and smoother power delivery on ungroomed outdoor tracks.

New features:

• New RC8B4.1e RWB/FWB adjustable weight bias chassis design to tune rear grip vs. steering

• New low CG and lightweight aluminum front and rear shock towers.

• New shorter 16mm front and rear shock bodies for lower CG and lighter weight.

• New 6-hole 1.4mm front and 1.5mm taper rear machined shock pistons included with emulsion shock cap seals.

• New 3-hole rear suspension arms with updated rear anti-roll bar geometry for both smooth and bumpy tracks.

• New durable rear hub design with wide footprint base, and tuneable 3mm carbon fiber hub towers.

• New blue aluminum front upper arm mount for added durability.

• New molded RC8B4.1 front bumper with optimized profile for bumpy transitions.

• New 47T molded spur gear.

• 44/13 Ring and Pinion Bevel Gear Set.

• 92mm universal driveshafts with 17mm outdrives.

• Updated Soft Blend suspension arms for maximum durability in cold weather.

• New +1 aluminum steering block arms for sharper steering on low grip.

And all the technical features that have made the RC8 B4 such a success:

• Innovative new pivot ball front suspension geometry improves steering balance and provides predictable handling in all conditions.

• RC8B4 8deg. steering blocks are paired with a wider upper suspension arm pivot for increased stability and consistent steering through the entire steering throw.

• RC8B4 gearboxes are included in the latest hard material used on RC8T4: 1) Front gearbox features a 3.5deg. inclined pinion gear angle to straighten the center driveshaft for increased drivetrain efficiency and reduced phasing and vibration. 2) Both gearboxes feature large bearing sizes, 6x13x5mm flanged bearing results in longer life of bearings and ring and pinion gears.

• RC8B4 rear chassis brace has several design features and flex options: Rear brace is mounted centrally to the gearbox, and has two screw locations through the chassis to tune flex.

• RC8B4 front upper suspension arms, now in soft blend material. Includes an optional molded "wing" insert for increased front-end downforce.

• RC8B4 front lower suspension arms, now in soft blend material. 1) Updated design for added durability. 2) New angled, one-piece, anti-roll bar link is mounted in-line with the anti-roll bar with a BHCS instead of a shock pin for simplified assembly. 3) Optional inserts mount to the top only.

• RC8B4 rear wing mount has adjustable wing angle shims, significant strength improvements, an aerodynamic shape, and extra clearance for shock position adjustment. Two wing height options on the rear shock tower.

• RC8B4 rear wing has more vertical fins for increased straight-line stability, a taller rear lip height for increased downforce, increased strength in various areas to reduce bending fatigue, and dimples on the backside as a template for cutout holes.

• RC8B4 steering bellcranks with top-mounted steering rack for extra clearance around gearbox assembly.

• RC8B4 aluminum steering rack designed around the updated front end geometry is lightweight and durable

• RC8B4 steering bellcrank nuts are longer to reduce drag from the steering rack under flex.

• RC8B4 steering servo linkage features a new heavy duty threaded ball-and-steel screw joint.

• RC8B4 A and B blue aluminum suspension arm mounts are shaped to interlock with the chassis.

• RC8B4 carbon fiber front top plate centralizes the front chassis brace for balanced flex in all directions.

• RC8B4 front chassis brace is the same length as the older chassis "short" version for ideal front-end flex.

• RC8B4 front body post is recessed into the front top plate and the reversible design is easy to mount.

• RC8B4 spring cups and shock rod end design has a locking screw to keep the cups in place during a crash.

• RC8B4 steel shock standoffs.

• Large diameter, Low-Profile SHCS are used throughout the buggy to replace a traditional screw/washer system. Used on the fuel tank, servo mounts, and rear body post.

• New carbon fiber radio tray brace for repositioned steering servo.

• 93.5mm front and 104mm rear center dog bones with 3x14mm pins for increased drivetrain efficiency.

• RC8B4 two-piece rear body post features a rubber grommet to allow some flex to extend the life of the body

• RC8B4 rod ends have improved thread engagement, slotted area for easy turnbuckle wrench access, and are made from a same durable material as our 1:10 rod ends.

• Standard wheel hex sizes include a "+0" mm front and rear.

• Standard anti-roll bar sizes include a 2.2mm front and 2.5mm rear bar.

• RC8B4 Mu (pronounced "mew") body with RWB trim lines added. Includes three different style of gearbox noses: a traditional nose cone, a mid-height wing, and tall-height wing.

• 44T ring and 13T pinion gears on front and rear differentials.

• 16mm shocks equipped with white front (9.25 coil) and pink rear (12.0 coil) springs, emulsion style shock bladder, combination bleeder/emulsion caps, and blue aluminum threaded collars.

• RC8B3.2 narrow C and D arm mounts.
