Our take on the ARRMA Kraton 4X4 4S BLX Suspension Arm Set

This is a replacement suspension arm set for the ARRMA Kraton 4X4 4S BLX, sold as a pair of arms in black tough composite. It is a repair part, not an upgrade, so it fits the stock Kraton 4S and other 4x4 ARRMA models that share the arm design. The set weighs about 43 g and each arm measures roughly 10 x 10 cm. At $9.19 at Ludington Hobbies as of November 5, 2026, it sits at the low end of what these arms cost new, with only two stores pricing it.
