Chevrolet Small Block/Big Block Nylon Distributor Shim Kit by Davis Unified Ignition®

Three nylon shim thicknesses allow distributor height to be adjusted without stacking gaskets.

These high-impact nylon shims raise the distributor mounting flange when engagement measurements show that the distributor sits too low. Correct height helps prevent the shaft from bottoming against the oil-pump drive and damaging the distributor or camshaft gear. The kit offers three thicknesses for selecting the required clearance. Check distributor and oil-pump engagement before choosing a shim; a milled or decked engine does not automatically need all three.

• Chevrolet Small Block and Big Block distributor mounting (See full fitment list below) • High-impact nylon distributor shims • Includes 0.030-, 0.060- and 0.100-inch thicknesses • Adjusts mounting height when engagement measurements require it • Avoids using a stack of gaskets as the height adjustment
