GPI - LT1 Drop-In Piston / Connecting Rod Package
Bulletproofing the LT for Boost
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.
unlike the LS – 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.
Overcoming Limitations
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!
The Solution
Gwatney Performance is proud to present a Complete Drop-In Piston and Rod solution for the Gen V LT1 / LT2 (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!!
Results?
Reliable and consistent high horsepower Gen 5 LT’s! Here is a recent build with these pistons. This is a street car, so power and boost levels are fairly conservative.

- GPI LT Cylinder Heads
- GPI LT Camshaft (SS1)
- G1Pro Sheet Metal Intake Manifold w/ GPI Port Fuel Injection System
