*Note that the largest size spring we can recommend running is a 500 lb Fox SLS spring (52.5 mm OD). Plenty of frames out there can fit a larger spring than this, but because of the variation we’ve seen between frames, a 52.5 mm OD spring is the largest that will fit any frame. If you are interested in running a coil and need a larger OD spring make sure to check the clearance between the spring and the drive side of the shock tunnel. This is where the fit is tightest.
