What is the primary benefit of using ARP 625+ bolts with these rods?

ARP 625+ bolts offer significantly higher tensile strength and fatigue resistance compared to standard rod bolts. This makes them ideal for high-performance SR20 engines that will experience increased cylinder pressures and higher RPMs, ensuring the connecting rods remain securely fastened.

What other components are typically needed when installing this connecting rod kit?

When installing this kit, you will also need compatible pistons, piston rings, wrist pins, rod bearings, and appropriate assembly lube. It's also recommended to have your rotating assembly professionally balanced.

Are these rods balanced from the factory?

While the rods themselves are manufactured to tight tolerances, it is highly recommended to have the entire rotating assembly, including these rods, pistons, and crankshaft, professionally balanced for optimal engine performance and longevity.

Product Details

This is the BoostLine connecting rod kit specifically for Nissan SR20 engines, featuring 136.25mm rods and ARP 625+ bolts. If you're building a high-performance SR20, these rods are a critical component for handling increased power and stress. They are designed to be a direct replacement for your stock rods, but with a significant upgrade in strength and reliability.

BoostLine rods are forged from high-strength steel, giving them the durability needed for demanding applications. The ARP 625+ bolts are a standout feature here; they are known for their exceptional tensile strength and fatigue resistance, which is crucial for keeping your connecting rods securely fastened under extreme cylinder pressures and RPMs. This kit includes the rods and the ARP bolts, ensuring you have the core components for a robust engine build. The 136.25mm length is a common upgrade size for SR20 builds, often used to achieve specific compression ratios or piston deck heights when paired with appropriate pistons.

When installing these rods, it's important to ensure your crankshaft journals are properly prepped and that you use the correct assembly lube. Precision balancing of the rotating assembly is also highly recommended to ensure smooth operation and longevity of your engine. This kit is a solid foundation for anyone looking to push their SR20 beyond stock power levels.
