GWATNEY PERFORMANCE - LT1DROPINS - $1649
LT1/L86 DROP IN PISTON/CONNECTING ROD PACKAGE
The LT series GM engines are incredible powerplants as designed – however unlike their predecessor (LSx) – the LT’s commonly rebel when power adders such as superchargers, turbos, and nitrous are added.

The LT powerplants have several weak links when boosted:

  • the unique piston and ring land design which was intended for naturally aspirated duty is subject to failure under even minimal detonation.
  • preignition has been associated with various detergents found in certain motor oils which become emulsified resultant of the fuel being sprayed under pressure into the cylinder creating unintended combustion
  • We have found ring end gaps as small as .008 which will certainly butt together causing cylinder, piston and ring failures when subjected to increased heat and cylinder pressure.
  • We have found LTI connecting rods during engine upgrades on stock forced induction engines which were slightly bent even though they were still asymptomatic.
  • Understanding these limitations – and because GPI strives to provide the best combination of power and reliability for our clients – we have worked with Diamond Racing and Callies to offer a no rebalance, standard bore, stock compression, drop-in solution for the Gen V 6.2 liter LT1 engine.
  • What does this mean for you?  No machine work and no balancing needed.  This is a complete drop-in assembly that can be installed while the engine is still in the car!

  • Gwatney Performance is proud to present a Complete Drop-In Piston and Rod solution for the Gen V LT1 (6.2) Engine!  This package is designed specifically for boosted 14+ Corvette’s and 16+ Camaro SS.

    By working directly with Diamond Racing and Callies, and were able to get the exact same bobweight as the factory piston / rod assembly, and due to the heavier weight of the factory assembly – we were able to build an extremely robust piston and rod package.

    This kit is designed to support 1000+HP applications and is the perfect match for your forced induction LT!!
