Front left upper and lower A-arms for the Arrma Kraton 8S and Outcast 8S. The set is 4.5 grams lighter than stock per upper and lower pair. These vehicles weigh about 26 lbs (12kg), so the arms are built for hard landings and collisions. The lower A-arm uses a triple beam design so impact energy is spread across three beams, and each beam measures 5/8 inch (15.8mm) tall by 3/8 inch (9.5mm) wide. The beams limit unwanted flex during normal suspension travel while still absorbing impacts. The inner cross brace has been moved away from the chassis, which removes the droop stop. Test trucks with stock geometry bent their chassis at the droop stops under extreme impacts.
