| Description |
| HIGH STRENGTH T-6 heat treated 2618 primary aluminum alloy. Diamond machined skirt, head, mini-grooves, pin bore, gas accumulator, and ring grooves. Pressure drilled pin hole oiling on all forged pistons. V-Rib design for lightweight, strength, and maximum piston cooling. Compare weight, performance, design, and cost ... you will win with KB! |
| Modern piston design locates the top right higher for improved performance. A high top operates at higher temperatures and requires a larger top ring end gap. Lock rings and pins are included with no separate cost. Hyper pistons have a low conductivity of the alloy and a reflective piston top surface which lowers oil temperature, reduces combustion heat and pressure loss. |
