ACS3 Fork Coil Conversion Kit for 2014-2020 Rock Shox 15x110 BOOST Axle PIKE RC/RCT3/RC2

Optimized Lightweight Design

Why is everyone always trying to sell you on “coil-like”
performance? Because nothing beats a coil when it comes to small bump
sensitivity, traction, and mid stroke performance. Also, coil springs eliminate the constant maintenance required to keep your fork running optimally!

The downside of coil suspension? They lack the big hit performance and bottoming control provided by today's air systems. But, what if there was a complete system that provided both? Introducing the PUSH ACS3 Coil Conversion System!

The Ultimate Fork Spring

Don't settle for spring rates measured in "soft", "medium", and "firm"! PUSH ultra-light fork springs are precision engineered and CNC wound for exacting rate tolerance. We offer seven spring rates available in 5 lb/in increments ensuring you get the exact rate you need without compromise.

Air Bump Stop Technology

Used in conjunction with our Coil main spring, our patent-pending Air Bump Stop cartridge allows you to independently fine tune the progressiveness of your fork. Using a standard suspension pump, pressures can be set between 5-50psi for your desired bottoming control. Lower pressures provide a more linear fork feel, while higher pressures provide a quicker engagement and more progressive performance for big hit riding. All without interfering with the first 65% of the forks travel.

"Made Here"

Much like all PUSH products, the
ACS3 is hand assembled from components that are 100% manufactured here in Colorado. Precision machined from premium raw
materials to minimize weight without sacrificing performance or durability.
Initially developed for or ELEVENSIX shock, our exclusive Micro-XD coatings can
be found on our Air Bump Stop unit as well as the lower plunger rod. This
coating provides a durable and slippery surface leading to decreased wear,
better traction and better small bump sensitivity.
