PUSH Industries ACS3 Spring Assembly

This kit is designed specifically for RockShox Yari and Lyrik forks manufactured from 2016 to the present. It will not fit other fork models or brands.

The ACS3 replaces the progressive nature of an air spring with a consistent, linear coil feel. This typically results in better small-bump sensitivity and increased traction, making the fork feel more planted and responsive on technical terrain.

Yes, the kit includes two preload spacers that allow you to fine-tune the spring preload to match your riding style and weight. This gives you a level of customization similar to adjusting air pressure, but with the distinct characteristics of a coil spring.

The ACS3 is optimized for aggressive enduro and all-mountain riding where traction and consistent performance on long, demanding descents are prioritized. If you are looking to shave weight for cross-country racing, a standard air spring setup may still be preferable.

Yes, the package includes the coil spring, the preload cap, and two preload spacers. You will need standard suspension service tools to perform the installation, but no additional parts are required to convert your fork.
