RPM Rear A-arms for the ARRMA Kraton 4S BLX & Outcast 4S BLX
Quick Notes:- Nearly 25% thicker than stock a-arms for extreme durability
- Less slop for improved suspension and steering performance
- Second shock mount hole for added adjustability
- Replace stock ARRMA #AR330521
RPM A-arms for 4S BLX versions of the ARRMA Kraton & Outcast are designed primary for strength and durability but weve added a few extra features in as well.
First is slop elimination. Our A-arms reduce the amount of movement of the A-arm at the hinge pins, providing for better steering response and more consistent camber, caster and toe angle settings.
Our next 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.
Our most important update is durability. Our new A-arms are massive! At almost 25% thicker than stock, our A-arms will take a pounding and come back for more! All RPM A-arms are molded from our 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. Rear A-arms replace stock #AR330521.
