HKS 21004-AN016 Forged Piston Kit + Connecting Rods Nissan GT-R VR38DETT

GT800 Package can release the restriction by replacing the pistons and connecting rods with the HKS Piston Kit and Connecting Rod Set which enables higher performance. This HKS Piston Kit and Connecting Rod Set are the best to use with GT800 Package to upgrade the engine properly.

The bore sizes of both Piston Kit and Connecting Rod Set are the same as the factory sizes so they can be replaced with the factory parts.
To avoid piston land breakage, HKS pistons are made with forged material instead of casting like the factory pistons.
It's recommended to use with other items of the GT800 Package. In-house test at 900PS confirmed the durability and safety.
The setting range is widened by reducing the compression rate from 9.0 factory ratio to 8.7. This is effective to increase the engine output using the aluminum block specs and/or bigger cylinder bore.

The weight of the connecting rod is the same as the factory since the affect of the V6 engine's peculiar vibration should be considered.

The piston is light-weighted to approximately 25g.

The weight is optimized to install with the factory crankshaft so it is not necessary to use a dummy weight to balance.
