Overview
Take your Arrma Grom's suspension performance to race-spec with the Hot Racing CNC Aluminum 58mm Threaded Damper Shocks. CNC-machined from premium aluminum and built with hardened steel shafts, threaded bodies, and bleeder screws, this pair of pre-assembled 58mm shocks delivers true oil-damped performance in a fully tunable, rebuildable package — a massive upgrade over stock plastic Grom shocks.
Two spring rates are included — silver (stiffer) and black (softer) — so you can dial in chassis balance for any track surface or driving style. Threaded shock bodies enable tool-free preload and ride-height adjustment, and bleeder screws make routine shock maintenance fast and clean.
Key Features
- CNC-machined aluminum bodies, caps, collars, lower seal caps, ends, and retainers
- Hardened steel shock shafts
- Threaded bodies and collars for ride height and preload adjustment
- Bleeder screws for easy shock maintenance
- Two spring options included: silver (stiff) and black (soft)
- Rebuildable, pre-assembled design
Performance Benefits
- Race-grade oil damping for the 1/18 Grom platform
- Tool-free preload and ride-height adjustment
- Two spring rates for surface-specific tuning
- Far better consistency than stock plastic shocks
- Long-lasting, rebuildable construction
Usage Notes
Silicone shock oil of your choice is required — not included. Start with 30wt-40wt silicone oil as a baseline. Begin with the soft (black) springs front and rear, then mix and match to bias chassis balance for your terrain.
