Following an intensive design, development and testing program, ARC is proud to bring you the new R8.3 1/8th competition On-Road nitro chassis.
The ARC R8.3 features are:
All new internal gear ratio and 2-speed shoes
R8.3 FDR is 2.4. This improves acceleration and works better for small to medium size track, while the peak of top speed remains the same as R8.2. New design 2-speed shoes with hard composite formula, makes the 2-speed shifting time more consistent and precise.
All new chassis
Front end flex is adjustable by chassis cover, with installed front chassis stiffener, increasing steering response and avoid over-steering in high traction condition. The new battery plate also comes with a flex slot to increase chassis flex and stability.
All new upper deck and front bulkheads
New front bulkheads allow easier maintenance for front one-way axle and belt. New upper deck design connects the front upper arm and creates overall chassis flexibility, making handling less sensitive with track condition changes.
All new shocks
New shocks design improves traction with 2 soft O-rings inside. Shock membrane helps maintaining shock rebound. Rear shock extended 3mm and with 2 pieces of O-ring at bottom makes the shocks performance more consistent.
All new steering blocks
New front steering block improve handling especially in high traction. They use larger 21x12x5mm ball bearings with center axle. The optional backward offset axle inserts provide more on power steering. Useful tuning parts especially in low traction tracks.
