GPI – Complete Gen 5 LT1 / L86 Drop-In Piston / Connecting Rod Package (2014+ Corvette / 2016+ Camaro SS)

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.

The Solution

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 includes:

• (8x) Diamond Pistons with 2618 Forging Material in Standard (11.5:1) or Lowered (10.25:1) Compression Ratio
• (8x) 6.125 Compstar Connecting Rods
• (8x) Heavy Duty Pin, Locks, and Ring Package
• Designed to Support 1000+HP Applications
• No Balancing Required! Drop-In Piston and Rod Upgrade!!
