RPM ARRMA Kraton/Outcast 6S Front Left Upper & Lower Suspension Arms are an optional upgrade for ARRMA Kraton, Notorious, Talion, Fireteam & Outcast models. The design modifications incorporated accommodate changes made by ARRMA for V5 and EXB versions of these vehicles. However, they are reverse compatible for older models (see NOTE below). All RPM A-arms are molded from RPM's nearly indestructible blend of engineering grade nylons, for performance you can rely on when conditions get rough!
Beefier
RPM A-arms are significantly beefier than the original 6S version A-arms. Lower A-arm support beams are 30% thicker while upper A-arms are more than 22% thicker. The added thickness not only improves durability and strength, it also reduces flex. Less flex equates to more predictable suspension performance and handling.
Extra Suspension Options
The lower A-arm has an added shock mount hole further outboard. This additional position provides a lower profile suspension set-up. The shocks lay down a little further, dropping the ride height for a lower center of gravity. A lower center of gravity equates to higher corner speeds.

Caster Clip Elimination
As for the upper A-arm, RPM eliminated the caster spacers. This allowed room to widen the arm at the inner hinge pin mount. The extra width creates more of an “A” shape, stabilizing the upper A-arm. A more stable A-arm improves steering and suspension performance while adding strength and durability.

RPM Arrma Kraton/Outcast 6S Front Left Upper & Lower Suspension Arm Set (Black)
Two major issues I found with these arms when installing on the Arrma Talion 6s EXB, 1) The screw for the lower suspension hinge pin is blocked by the front drive shafts on the front arms. Making it very difficult to change suspension ride height as it requires you to remove the steering hub in order to get access to the screw that's under the drive shaft. 2) The suspension angle for the front shocks seems a bit off. I found using the further holes causes the suspension shocks to rub against the bottom portions of the arms. Also, once you install these arms, you're not able to use the Hot Racing Aluminum Shock ends. The angle the shocks are positioned limits the space at the bottom, now allowing you to use the product.

They mounted up perfectly and have proven themselves tough. Frank is right about the front driveshafts sitting directly above the release screw for the shocks lower mount. The upper A-arm has no shims so removing it is how I get to my shocks
lower mount. It's a minor issue. I've had nothing but good luck with the front arms but the back ones seem to be brittle and I have broken a bunch of them. I recommend RPM front arms, there a big improvement over the stock ones. I run Arrma EXB in the back.
