Description

The Swift H70-070-008 is a flat wire helper spring engineered to maintain coilover spring security during droop travel. It is specifically crafted to have a minimal impact on the primary coilover spring's rate. This helper spring features a 70mm length and a 70mm inner diameter, with a spring rate of 0.8 kgf/mm (45 lbs/inch). Its stroke is 48mm (1.9 inches), FCH is 22mm (0.9 inches), and CW is 45kg (99 lbs). The product is sold as a single spring and includes a Stack Spring Adapter, facilitating easy installation and integration with existing coilover setups. The helper spring is fully compressed at static height, and its design allows for ride height to remain unaffected when installed. This feature is particularly beneficial for fine-tuning rebound travel and preventing inside wheel lift during hard cornering.
