ARRMA MINI KRATON 3S Rear Alloy Shock Set 74mm MAKM074R by GPM  [MAKM074R]

Premium alloy rear dampers for Mini Kraton 3S

This package contains alloy-bodied rear shock absorbers developed for the ARRMA 1/16 MINI KRATON 3S platform. Each 74mm centre distance body is pre-filled with 500cSt silicone oil to offer consistent damping characteristics out of the box.

Design choices prioritise serviceability and controlled tuning. Bleeder screws are fitted so oil and trapped air can be released easily during maintenance, while threaded preload rings let you change ride height and initial spring compression without stripping the unit. The kit uses 3.0mm shock shafts in place of the stock 2.5mm shafts, delivering improved shear stiffness to reduce flex under load on small-scale trucks.

Included are two springs: a black 1.2mm wire spring installed at the factory and a spare silver 1.3mm wire spring that provides a firmer rate for reduced rear squat. These options make it straightforward to tune rear traction and response by swapping springs and altering preload.

Installation guidance: intended to replace rear shocks with a 74mm centre measurement. Use proper thread-lock if metal-thread fasteners are reused, and bleed the shocks after final filling to remove internal air pockets for uniform damping.

For racers and club drivers after a metal-bodied rear shock with simple servicing and modest tuning range for the 1/16 Mini Kraton 3S, this set brings stronger shafts, bleeder fittings, and an alternate spring for quick rear handling adjustments.
