RPM Suspension Arms for ARRMA Kraton & Outcast

The latest performance upgrade for monster truck owners are the RPM suspension arms for Arrma Kraton and Outcast vehicles. RPM has produced Front A-arms (#80822) and Rear A-Arms (#80742) that will work on either the Arrma Kraton 4×4 4S BLX or the Arrma Outcast 4×4 4S BLX.

These RPM A-arms for 4S BLX versions of the ARRMA Kraton and Outcast are designed primarily for strength and durability, but there are a few extra features in as well. First is slop elimination. RPM A-arms reduce the amount of movement of the A-arm at the hinge pins, thus providing better steering response and more consistent camber, caster and toe angle settings.

Another improvement is the addition of a second shock mount hole further out on the arm, providing for 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 tells us that the most important update is durability. These new RPM A-arms are massive! At almost 25-percent thicker than stock, these A-arms will take a pounding and come back for more. All RPM A-arms are molded from their nearly indestructible blend of engineering grade nylons for performance you can rely on when conditions are at their worst.

Tech Notes: RPM A-arms for 4S versions of the ARRMA Kraton & Outcast are sold in pairs. Front A-arms replace stock ARRMA #AR330520 while rear A-arms replace stock #AR330521.
