Built for continuous heavy-duty operation

This kit has now logged 12,000+ hours in our power generation QSK78 under 24/7 operation. The piston crowns show minimal carbon buildup and the ring lands remain within wear limits. The thermal barrier coatings are holding up exceptionally well. Essential maintenance for maximizing engine life between major overhauls.
