Now refined and improved for 2026, this latest version significantly improves clearance and accessibility and features key upgrades for easier use, faster spring swaps, and better fitment — all while retaining the competitive price and rugged durability that made it a workshop favourite.\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cstrong\u003e💡 DID YOU KNOW?\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003e300M Steel makes the difference.\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eOur latest compression cups are 3D printed from\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e300M Aerospace Steel\u003c\/strong\u003e. This ultra-strong material allows for a significantly slimmer wall profile, giving you vastly improved visibility and magnet access to the valve collets without sacrificing the strength needed for 140lb+ race springs.

This tool eliminates that hassle entirely by using compressed air to hold the valves shut while you swap components.
