RPM A-arms for the Axial EXO Terra Buggy are designed with unique features found only on RPM A-arms. We use 30 degree leading and trailing edges, which help the vehicle transition up and over tall objects instead of plowing into or through them. Our oversized bosses for the hinge pin, shock mount and screws help support high breakage areas. Key oversized areas can be larger in diameter by at least 10% and wider by as much as 65%! RPM engineers tweaked the shock mount angle on our rear A-arms to eliminate the bind on the lower shock pivot ball at full suspension droop found with stock a-arms. A full set of front and rear A-arms from RPM weigh in less than stock arms as well, shedding unsprung weight in the process of adding some much needed muscle. A final, critical touch eliminates much of the slop from the suspension and steering systems. Hinge pin hole diameters are now .118” (or 3mm), cutting nearly .004” (.1mm) of slop from each hinge pin!
RPM EXO A-arms are molded from our trademark blend of incredibly strong materials and are sold in black. All RPM molded products are backed by our limited lifetime warranty against breakage. Bolt a set on and feel comfortable knowing your ride is protected by RPM!
Tech Notes: EXO owners: to reduce excessive free play in the suspension and steering systems even further, RPM recommends purchasing true, on-size 3mm (.118”) hinge pins to replace the threaded rod used at the inner hinge pin location in both the front and rear locations of the EXO (not available through RPM). Stock threaded hinge pins are undersized by .004″ (.1mm).
