DESCRIPTION:
Our front lower A-arms have a triple beam style construction designed to spread impact energy across all three beams. Each beams 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. We also moved the inner cross brace away from the chassis, eliminating the droop stop entirely. While this may seem counter-intuitive, our test trucks chassis was bent at the droop stops, clearly illustrating that extreme impacts were too much for the chassis plate to handle. After all, theres not much worse than a bent chassis.
Our 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. We 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 our trademark blend of ultra durable materials, you cant go wrong with RPM!
Version:
