Front left upper and lower A-arms for the ARRMA Kraton 8S and Outcast. These 26 lb (12kg) monsters are built for high-flying, dirt-shredding jumps, and these arms are made to handle the abuse. The lower A-arm uses a triple beam design so impact energy spreads across all three beams. Each beam measures 5/8" (15.8mm) tall by 3/8" (9.5mm) wide. The beams cut unwanted flex during normal suspension travel but still absorb hits from rough landings and crashes. The inner cross brace was moved away from the chassis, which eliminates the droop stop. Test trucks bent their chassis at the droop stops, so this change keeps the plate from taking that hit. The upper A-arm uses a dual beam design, with each beam 1/2" (12.7mm) tall by 3/8" (9.5mm) wide.
