Kraton/Outcast 6S Front Left Upper & Lower Suspension Arm Set (Black)
Kraton/Outcast 6S Front Left Upper & Lower Suspension Arm Set (Black)
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.
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.
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.
