ARRMA ARA-1560 Aluminum Shock Set 58mm GROM

This ARRMA aluminum shock set provides four fully assembled 58mm shocks for the GROM platform, pre-filled with 2000cSt silicone oil and finished in gunmetal. As an upgrade over the stock composite dampers, aluminum bodies bring better heat dissipation and far greater impact resistance — the difference between a shock that survives a bad landing and one that cracks.

Each shock arrives completely assembled with springs installed and oil filled, so installation is a straight bolt-on swap with no build work. The 2000cSt oil fill is a firm, controlled damping rate suited to the GROM's light weight and quick suspension action.

The CNC-machined aluminum bodies have a smooth internal bore finish, which lets the piston and seals glide consistently through the stroke — that's what delivers predictable damping rather than the stiction you get from a scored or rough body.

Fitment covers the ARRMA GROM platform including the Typhon GROM and Granite GROM. The package includes four assembled aluminum shocks.
