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: 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).
