The addition of this mini skid steer, single-stick mod kit simply addresses a segment of the market that needed just four (4) springs instead of eight (8).\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003eWith this new kit offering we remain committed to our primary design and engineering objectives...\u003c\/div\u003e\n\u003cdiv\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimum Pre-Load \u003c\/strong\u003e- Pre-Loads engineered into the springs helps to keep the joysticks in the home position.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiston Protection\u003c\/strong\u003e - unlike other kits in the market, we engineered into our springs a coiling feature that prevents the cut wire ends of the springs from reaching the plunger\/piston surfaces.

I work for a spring manufacturing company based in Oregon. All of our Pilot Control Spring Mod Kits were designed by our team for custom fit on my own personal AGT KU18e mini excavator. I wanted steadier resistance in the controls, improved feel, dampened bounce-back and smoother operation of hydraulic functions. We know springs and the Spring mod is all we do at Spring Pilot.\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003eWHAT ABOUT INSTALLATION?\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eNO CUTTING REQUIRED.
