1:8 scale truck is the R/C hobby's highest stress discipline; Associated Electrics' Area 51 created a new gearbox upgrade to absolutely bulletproof the RC8T4 drivetrain. The upgraded 40/9 ring and pinion are completely re-designed with massive teeth which allow for more tooth engagement and prevent skipping. In addition, the RC8B4 front and rear gearboxes are updated for the tightest possible screw and bearing fit using high stiffness polymer.
Team Associated driver Spencer Rivkin used the new parts win the 2024 ROAR Electric Truck National Title with his RC8T4e, never having to worry about the durability of his truck gearboxes while he pushed it to the max on track.Required to Complete:

Features:
RC8T4e chassis layout featuring two saddle pack-style battery configurations. Both configurations include a centrally mounted center differential and in-line center driveshafts for superior drivetrain efficiency and equalized chassis balance.
Four battery configurations to choose from: --Two 2S shorty LiPo batteries for lowest CG and exceptional weight bias --Two full size "saddle pack" LiPo batteries for lowest CG and exceptional weight bias --One 4S shorty LiPo battery for simplified setup and more centralized weight bias --One full size LiPo battery for simplified setup and more centralized weight bias.
Innovative front-end geometry with 8 degree steering blocks are paired with a wider upper suspension arm pivot for improved steering balance and predictable handling in all conditions.
RC8T4e gearboxes are specific to front and rear with larger bearing sizes resulting in longer life of ring and pinion gears: Front gearbox is a 3.5 degree inclined pinion gear angle to straighten the center driveshaft for increased drivetrain efficiency and reduced phasing and vibration. Rear gearbox is a 0 degree pinion gear angle and a center mounted rear chassis brace.
V2 front shock tower design with updated suspension geometry and body mount positions for all styles of truck bodies.
Front and rear center dogbone driveshafts for improved drivetrain efficiency and durability.
Front upper suspension arm updated to have bushing insert for improved fitment and performance.
RC8B4 rear wing mount has adjustable wing angle shims, significant strength improvements, an aerodynamic shape, and extra clearance for shock position adjustment.
The adjustable rear wing has more vertical fins for increased straight-line stability, a taller rear lip height for increased downforce, and increased strength in various areas to reduce bending fatigue.
RC8B4 rear chassis brace is mounted centrally to the gearbox, which reduces material fatigue, centralizes shear forces, and improves the life of rear-end drivetrain parts. There are three different chassis flex options using two chassis hole mounting locations and an optional turnbuckle ball for flex in more degrees of freedom.
+2 mm and +4 mm shock rod ends for finer adjustment of droop and up-travel settings.
35.5 mm front and 44.5 mm rear shock shafts for improved dampening
RC8B4 rear hub features a symmetrical left and right common design with axle height inserts for adju
