Overview
The HPI Racing Shock Spring (Soft) is a precision-wound 13.75-coil spring designed as a direct-fit replacement or tuning option for the HPI Venture18. With a 10mm OD, 33mm length, and 0.5mm wire diameter, this soft-rate spring is ideal for technical crawling, rock work, and slow-speed scale driving where maximum suspension compliance is needed.
Softer springs allow the suspension to articulate more freely over uneven terrain, helping the tires stay in contact with the ground for better traction.
