Connecting rod rebiuld kit

• High-quality replacement kits are manufactured from hot-rolled alloy steel and case-hardened.
• Advanced design uses strategically located side scalloping and vent slots to minimize high rpm bearing race distortion.
• Rods are also shot-peened and double-honed for superior strength under heavy loads.
• Small ends are double drilled to supply extra lubrication and cooling to the wrist pin bearing, which is especially important when the piston crown is close to the wrist pin bearing.
• Thrust washers and crank pin bearings are silver-coated for added lubricity.
• Kits sold complete with rod, crank pin, crank pin bearing, top end bearing and thrust washers.
