Overview

The Team Associated RC8B4.1 RWB is the refined evolution of the 2022 IFMAR World Champion RC8B4, built for top performance on outdoor tracks. With a stiffer, tapered chassis for improved high-speed stability and a lower center of gravity, it delivers enhanced handling and balance. New low center of gravity shock towers, shorter shocks, and 3-hole rear springs allow for a smoother setup without loss of cornering support. Wide rear hubs with carbon fiber towers offer versatile geometry options, while the universal 92 mm hubs and optimized gearing provide smooth, consistent power and maximum grip on rough terrain.

Features

• New RC8B4.1 RWB chassis and side guards with tapered chassis design for increased stiffness and predictability
• New low center of gravity and lightweight aluminum shock towers front and rear
• New shorter 16 mm shock bodies front and rear for a lower center of gravity and reduced weight
• New 6-hole 1.4 mm front and 1.5 mm tapered rear shock pistons, including emulsion shock cap seals
• New 3-hole rear control arms with updated stabilizer bar geometry for both smooth and bumpy roads
• New durable rear hub design with wide footprint and adjustable 3 mm carbon fiber hub towers
• New blue aluminum upper arm mount for extra durability
• New cast RC8B4.1 front bumper with optimized profile for bumpy transitions
• New 47T machined gear
• 44/13 ring and pinion tapered gear set
• 92 mm universal drive shafts with 17 mm output shaft
• Updated Soft Blend control arms for maximum durability in cold weather
• New +1 aluminum steering block arms for sharper steering on low grip

RC8B4.1 Team Kit Legacy Features

• The innovative new front wheel suspension geometry with ball joint improves steering balance and provides predictable driving behavior under all conditions.
• The RC8B4 8-degree steering blocks are combined with a wider upper arm hinge for more stability and consistent steering throughout the entire steering range.
• The RC8B4 gearboxes are made from the latest hard material also used on the RC8T4: 1) The front gearbox has a 3.5-degree angled gear to align the center driveshaft for higher drivetrain efficiency and less phasing and vibration. 2) Both gearboxes have large bearing sizes; a 6x13x5mm flange bearing results in longer bearing life, ring, and pinion gears.
• The latest version of the RC8B4 fuel tank with: 1) Flexible rubber lid puller. 2) Updated spring for a good seal between lid and tank.
• The RC8B4 rear chassis brace has various design features and flexibility options: the rear brace is centrally mounted on the gearbox and has two screw points through the chassis to adjust flexibility.
• The RC8B4 front upper arms are now made of soft material. Includes an optional molded "wing" insert for more front downforce.
• The RC8B4 front lower arms are now made of soft material. 1) Redesigned for extra durability. 2) The new, angled, one-piece sway bar is mounted in line with the sway bar using a BHCS instead of a shock pin for simplified assembly. 3) Optional inserts are mounted only on the top.
• The RC8B4 rear wing mount features adjustable shims for wing angle, significantly improved strength, an aerodynamic shape, and extra space for adjusting the damper position. Two options for wing height on the rear shock tower.
• The RC8B4 rear wing has more vertical fins for increased straight-line stability, a higher rear lip for more downforce, added strength in various places to reduce bending fatigue, and dimples on the back as a template for cutouts.
• The RC8B4 steering crankshafts with top-mounted steering housing for extra space around the gearbox.
• The RC8B4 aluminum steering housing, designed around the updated front geometry, is lightweight and durable.
• The RC8B4 rocker nuts are longer to reduce resistance of the steering housing during flex.
• The RC8B4 steering servo connection features a new, robust ball and steel screw connection with threading.
• The blue aluminum suspension arm mounts of the RC8B4 A and B are shaped to fit into the chassis.
• The RC8B4 carbon fiber front top plate centralizes the front chassis brace for balanced flex in all directions.
• The RC8B4 front chassis brace has the same length as the older, short version of the chassis for ideal front flex.
• The front body pin of the RC8B4 is recessed into the front top plate and the reversible design is easy to install.
• The RC8B4 spring cups and shock shaft end have a set screw to keep the cups in place during a crash.
• Steel spacers for the RC8B4 shock absorber.
• Large diameter, low-profile SHCS are used throughout the buggy replacing a traditional screw/washers system. They are used on the fuel tank, servo mounts, and rear body tube.
• New exhaust mount and spring.
• New carbon fiber radio mount for a relocated steering servo.
  93.5 mm front and 104 mm rear in the center with 3x14 mm pins for higher drivetrain efficiency.
• The two-piece rear body tube of the RC8B4 features a rubber grommet for some flexibility and longer body life.
• The RC8B4 rod ends have improved threading, a slot for easy access with a spanner wrench, and are made from the same durable material as our 1:10 rod ends.
• Standard wheel hex sizes include a "+0" mm front and rear.
• Standard stabilizer bar sizes include a 2.2 mm bar front and 2.5 mm rear.
• RC8B4 Mu (pronounced "mew") body with added RWB finishing lines. Includes three different types of gearbox noses: a traditional nose cone, a mid-height wing, and a high wing.
• 44T ring and 13T pinion gears on the front and rear differentials.
• RC8B3.2 battery and receiver with removable transponder mount.
• RC8B3.2 split center diff mounts with aluminum center plate.
• 16 mm shock absorbers equipped with white front springs (9.25 coil) and pink rear springs (12.0 coil), emulsion-type shock absorber bladder, combined vent/emulsion caps, and blue aluminum coil rings.
  RC8B3.2 narrow C- and D-arm mounts.
• 4-shoe aluminum clutch with two composite and two aluminum shoes, two 0.95 mm and two 1.0 mm springs, and a steel 13T clutch housing.
