GPM Racing Alloy Rear Shock Absorbers 74mm for Arrma 1/16 Mini Kraton 3S Dsc 4x4 RTR Brushless Speed Truck (MAKM074R)

Alloy rear shock set for the Mini Kraton 3S

This product is a set of alloy rear shock absorbers designed for the ARRMA 1/16 MINI KRATON 3S. The 74mm centre-to-centre aluminium bodies are pre-filled with 500cSt silicone oil to provide a stable starting point for suspension adjustments.

Service-friendly features are emphasised: bleeder screws permit easy air and oil release, threaded preload collars let you set ride height without disassembly, and 3.0mm shock shafts increase stiffness compared to the 2.5mm originals to reduce flex under load at this scale.

The kit includes a factory-installed black spring with a 1.2mm wire and an extra silver spring with a 1.3mm wire to offer a firmer option. These allow quick rear tuning by spring swapping and preload changes to control traction and squat.

Installation note: intended to replace rear absorbers with a 74mm centre distance. Use thread-lock on metal fasteners if needed and bleed the shocks after filling to remove trapped air for consistent damping results.

Suitable for hobbyists who want a metal-bodied rear shock with easy servicing and modest tuning range for the 1/16 Mini Kraton 3S, this MAKM074R set offers beefed-up shafts, bleeder screws and an alternate spring for incremental handling changes without major chassis work.

Do these fit the stock rear shock locations directly?

They are made for rear shock positions that use a 74mm centre distance on the 1/16 Mini Kraton 3S; confirm eyelet format and stud spacing before installation to ensure fit.

Is the pre-filled oil the recommended starting point?

The factory uses 500cSt silicone oil to offer a consistent baseline; you can swap oil weight during service to adapt damping to different driving surfaces or preferences.

Which spring should I try first on a balanced setup?

Start with the fitted black 1.2mm spring to retain stock behaviour and only move to the stiffer 1.3mm silver spring if you need less squat or a firmer rear response.

Any special steps after changing oil or springs?

After servicing, bleed each shock to remove trapped air, check shafts for straightness, and verify preload and ride height before running to ensure consistent damping. Write Product Review Please sign in your account before you can write any review. Sign In Close
