Front A-arms: Losi Tenacity / U4 Lasernut

RPM A-arms for the Losi Tenacity line of vehicles are designed with strength and durability as their primary goals. The result - a set of ultra strong, incredibly durable A-arms that are sure to exceed the demands of racers and bashers alike. RPM Tenacity A-arms are designed using 30 degree leading and trailing edges. A shape that gives each A-arm a slim, aerodynamic shape and helps their A-arms transition up and over objects instead of bluntly plowing into them. Key areas that needed additional strength, such as the outer hinge pin support diameters, have been beefed up by as much as 60%. That means those less than perfect "incidents" won't end your day of fun.
For performance enhancements, RPM tightened the slop out of the A-arm. Less slop creates a much smoother, more consistent platform for reliable camber, caster and toe angle settings. Suspension geometry has been left to stock settings. Stock geometry makes installing a set of RPM A-arms a simple swap with very little needed to be done to get back on the track.
RPM A-arms for the Losi Tenacity are sold in pairs. They're also molded in RPM's trademark blend of nearly indestructible nylons and manufactured in the USA!
