PRODUCT DETAILS

Description

Updates stock 107\", 114” or 117” motor to 124” or 128” when using 4.250” big bore cylinders

Valve pockets are designed to accept up to +4.00 mm oversized intake and exhaust valves

Type 3 hard-anodized crown offers corrosion resistance for alcohol-added fuels

Type 3 hard-anodized top ring groove eliminates micro-welding of ring to the groove and gives a hard-flat surface for ring to rotate on

OE-style round wire locks are easily installed

Heavy-duty wrist pins with true .9270” diameter to fit rods correctly

Line2Line AST skirt coating starts out with a near-zero wall clearance and through the break-in period hones the cylinders to produce the correct oil wedge, keeping the piston square to the cylinder for best ring seal and quiet operation

Kit includes pistons, rings, pins and locks
