Yokomo YAS-675 Big Bore Front Shock Spring (Black) for Carpet/Astro turf  [YAS-675]

Big bore front shock spring for carpet and astro turf

The Yokomo YAS-675 is a front shock spring developed for high-grip artificial surfaces such as carpet and astro turf. Designed as a big-bore front spring, its shortened overall length allows a lower ride height while providing more controlled landings and reduced tendency to snag on corner edges common to artificial turf.

In practice this spring helps manage jump impacts and suppresses the abrupt corner “catch” that can unsettle a vehicle on synthetic surfaces, reducing the chance of a high-side reaction. The characteristic is best described as a spring choice that promotes steadier landings and predictable front-end behaviour without changing existing shock bodies or mounting hardware.

Tuning role and installation notes: use the YAS-675 as a direct front-spring option where your shock assembly accepts big-bore springs, and pair it with appropriate damping and preload settings to match track conditions. Because the spring shortens total stroke height, verify ride height after fitment and adjust shock pistons or preload collars as needed to maintain desired suspension travel and steering feel.
