Shinn Kiteboarding Twintip Fin Shims

Shinn Kiteboarding Twintip Fin Shims are precision plastic spacers designed to fine-tune fin angles and eliminate movement in your fin box.

Use them to give your board tighter turns and improved pop, enhanced grip and top-end speed. This small addition can really change the way your fins perform.

These shims can also correct fin alignment, fill voids, and optimize your board's handling characteristics without requiring adjustable hardware. 

Simple to install: loosen fin screws, insert the shim under the fin base, and retighten evenly.

Suitable to fit most fin screw spacings.
