Thank you for purchasing this Team Associated product. This assembly manual contains instructions and tips for building and
maintaining your new Kit. Please take a moment to read through this manual to help familiarize yourself with these steps.
We are continually changing and improving our designs; therefore, actual parts may appear slightly different than in the
illustrations. New parts will be noted on supplementary sheets located in the appropriate parts bags.
Check each bag for these sheets before you start to build.
Features in the RC8B4e Kit:
• New chassis layout featuring two shorty-style only battery configurations. Both configurations include a centrally mounted center
differential and in-line center driveshafts for superior drivetrain efficiency and equalized chassis balance.
• New two-piece clamping motor mounts make for secure mounting and allows for mounting of a 30mm motor fan.
• New battery trays with battery stops built in for easy battery position adjustments.
• New ESC tray with protective shield has two chassis positions 2x2s and 1x4s battery setups for ideal weight bias positioning.
• New receiver box with built in servo mounts has integrated cable routing and increased volume for taller antenna-less receivers.
• Innovative front-end geometry with new 8° inclined kingpin steering blocks are paired with a new wider upper suspension arm
pivot for improved steering balance and predictable handling in all conditions
• New gearboxes are specific to front and rear
• All new front lower, front upper, and rear suspension arm designs
• New rear wing mount has adjustable wing angle shims, significant strength improvements, an aerodynamic shape,
and extra clearance for shock position adjustment
• New 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
• New rear chassis brace has several design features and flex options
• New rear hub features a symmetrical left and right common design with axle height inserts for adjustable roll center tuning.
The standard bearing size used is an 8x16x5mm flanged but the hub will still accept 15x21x4mm bearing for tuning options.
• New steering bellcranks with top-mounted steering rack for extra clearance around gearbox assembly
• New aluminum steering rack designed around the updated front end geometry is lightweight and durable
• New steering bellcrank nuts are longer to reduce drag from the steering rack under flex
• Updated steering servo linkage features a new heavy duty threaded ball and steel screw joint
• New A and B blue aluminum suspension arm mounts are shaped to interlock with the RC8B4 chassis
• New RC8B4e specific 7075 aluminum hard anodized chassis features updates to strengthen the front and rear droop tab areas
and an increased width along kick up area, and accommodations for the electric specific layout.
• New upper suspension arm link mount is significantly wider than RC8B3 series, providing the required geometry for the new
8° steering blocks
• New front shock tower has strength improvements and allows for the upper suspension arm insert to be mounted from front
side via a recessed pocket, without disassembly of the tower from the gearbox
• New RC8B4e specific front top plate has been updated to fit the new steering geometry and an offset front chassis brace.
• New front body post is recessed into the front top plate and the reversible design is easy to mount
• New spring cups and shock rod end design has a locking screw to keep the cups in place during a crash
• New front shock bushings are 1.5mm longer, and rear shock bushings are 4mm than RC8B3 shock mounts
• New two-piece rear body post features a rubber grommet to allow some flex to extend the life of the body
• New side guards have integrated wire routing clips and are over 1 inch narrower than RC8B3.2e

Step 1:
Add shims on the ring gear
side to TIGHTEN gear mesh.
Subtract shims on this side
to LOOSEN gear mesh.
NOTE:
Start 1x Thick 0.2mm
Step 2:
Add or subtract shims here
to finalize diff side to side
play once gear mesh is
set from Step 1.
Recommended diff “side-to-
side” clearance (gearbox
assembly) 0.10 - 0.25mm.
Start with 1 x 0.1mm.
Note:
0.1mm shim can be used for
fine tuning of gear mesh
