Your cart is empty.Overview: RPM front lower A-arms have a triple beam style construction designed to spread impact energy across all three beams. Each beam’s cross-section is a whopping 5/8” (15.8mm) tall x 3/8” (9.5mm) wide. These massive beams reduce unwanted flex during normal suspension movement, yet allow impact-absorption during those not-so-perfect landings and crashes. RPM also moved the inner cross brace away from the chassis, eliminating the droop stop entirely. While this may seem counter-intuitive, the test truck’s chassis was bent at the droop stops, clearly illustrating that extreme impacts were too much for the chassis plate to handle. After all, there’s not much worse than a bent chassis. RPM front upper A-arms use a dual beam construction where each beam is a massive 1/2″ (12.7mm) tall x 3/8” (9.5mm) wide. They eliminated the tube shape over the hinge pin to eliminate built-in molding stresses while beefing up the leading edge hinge pin support to add some much needed strength and durability. Both upper and lower A-arms are molded with fingernail slots that allow easy access to remove the aluminum support ring (not included) at the pivot ball. Made in the USA from RPM's trademark blend of ultra durable materials, you can’t go wrong with RPM! Version Notes:: RPM A-arms work perfectly with 8S versions of the Kraton and Outcast using ARRMA ARA330569 Spring Perches. EXB models using ARRMA ARA330740 Spring Perches may experience interference issues at both the shock mount and sway bars. RPM does not recommend the use of a-arms on these vehicles since modification of the a-arms may be necessary to eliminate bind at the shocks and sway bars. Tech Notes:: RPM A-arms for the ARRMA Kraton 8S and Outcast 8S are sold as one upper and one lower in each kit. One left and one right will be needed to complete the front end of one vehicle

They fit very well, like the original ones, however there are no threads on the inside so you have to manually thread them with the existing parts. They also hold up good in very cold weather unlike the original parts.
