SPC Performance Duo-fit 1/16-inch shims, 25 per box, engineered with a tapered opening to give greater coverage with fewer shims. Zinc coated for corrosion resistance, each 1/16" shim fits openings from 9/16" to 5/8" and is intended for camber and caster adjustment where a wider seating range reduces part variations and simplifies inventory for alignment work.
