Arrma Kraton/Outcast 4S BLX V2 Front Suspension Arms (2)
RPM Arrma Kraton/Outcast 4S BLX V2 Front Suspension Arms (2)
Suspension Arms Overview:
These are the RPM Arrma Kraton/Outcast 4S BLX V2 Front A-Arms. Each pair of RPM A-arms is molded in a blend of nearly indestructible nylons and manufactured in the USA. These A-arms are designed to withstand even the toughest conditions, so you can push your vehicle to the limit without worrying about breakage. Performance has been improved by tightening the tolerances of the A-arm to create much smoother, more consistent suspension movement for reliable camber, caster, and toe angle settings. The suspension geometry is set to stock settings, which makes installing a set of RPM A-arms a simple swap with very little needed to be done to get back on the track.
These RPM A-arms feature a slim, aerodynamic shape that helps them transition up and over objects, rather than bluntly plowing into them. Designed with an extra shock mounting hole to provide a lower profile suspension set-up. This shock position allows the suspension to lay down a little further, dropping the ride height for a lower center of gravity and better cornering stability.! RPM has beefed up key areas such as the outer hinge pin support diameters by as much as 60%. This means that even less than perfect “incidents” won’t end your day of fun. Experience unparalleled performance on the track or off-road with these ultra-strong, incredibly durable A-arms.
