HKS Piston and Connecting Rod Kit - Nissan R35 GT-R

• 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 materials instead of casting like the factory pistons.
•  It's recommended to use the GT800 Package for incredible results.
• In-house test at 900PS confirmed the durability and safety.
• The setting range is widened by reducing the pressure rate from 9.0 factory rate to 8.7.  This is necessary to increase the engine output using the aluminum block specs and/or bigger cylinder bore.

Factory OEM Improvements:

• The weight of the connecting rods is the same as the factory. This because the affect of the V6 engine's peculiar vibrations are considered.
• The pistons shed weight by approximately 25g.
• The combined weight of all the HKS parts are optimized in order to harmonize with the factory crankshaft preventing the use a dummy weight to balance.

• The 3D profile for the pistons were chosen from various profile tests.
• The forged material was created exclusively for HKS and the optimal piston shapes were utilized.
• Wit the results of our analysis, the durability of the factory connecting rod was improved by approx 46% while still maintaining the balance in tact.
• All parts are MADE IN JAPAN (in-house product)
