Overview
Get the iconic look and air-damped feel of full-scale rock crawler shocks on your 1/10 vehicle with the Hot Racing 120mm Black Internal Spring Air Shocks. These slick, fully internal-spring shocks deliver excellent compression damping for technical crawling while looking the part on any scale or trail build.
CNC-machined aluminum bodies and 7mm stainless steel shafts handle the abuse of rock-strikes, hard landings, and aggressive crawling. Three included spring rates (soft, medium, hard) let you tune chassis compliance for any terrain or vehicle weight.
Key Features
- CNC-machined aluminum shock bodies
- Heavy-duty 7mm stainless steel shafts
- Air-damping internal-spring design
- Three (3) included spring rates for full tuning flexibility
- Black anodized finish (also available in green, red, silver, blue)
Performance Benefits
- Air damping delivers smooth compression behavior
- Three spring rates cover most chassis weights and terrains
- Heavy 7mm shafts resist bending under hard impacts
- Internal-spring design = clean, scale appearance
Usage Notes
Air shocks rely on the internal air volume for compression damping — keep seals clean and replace O-rings periodically for best performance. Install with provided ball mounts; choose spring rate based on chassis weight and terrain (soft for technical crawling, hard for heavy or aggressive setups).
