What is the advantage of using ARP 625+ bolts in these connecting rods?

ARP 625+ bolts are made from a premium alloy that offers significantly higher tensile strength and fatigue resistance compared to standard ARP 2000 bolts. This makes them ideal for high-stress, high-horsepower applications like boosted Subaru EJ engines, helping to prevent bolt stretch and failure.

What is included in this connecting rod kit?

This kit includes the connecting rods themselves, the ARP 625+ bolts required for installation, and the corresponding nuts. It is designed to be a complete package for replacing or upgrading the connecting rods in your engine.

Are these rods suitable for a stock engine rebuild?

While these rods are incredibly strong and well-built, they are typically used for performance builds or engines that have been modified for increased power, especially with turbocharging. For a completely stock, naturally aspirated engine, they might be overkill, but they offer a significant upgrade in durability and reliability if you plan on adding power later.

Product Details

If you're building a high-performance Subaru EJ20 or EJ25 engine for turbo applications, you need connecting rods that can handle the stress. This BoostLine kit is built for just that, featuring strong, well-built rods designed to keep your engine running reliably under demanding conditions. They are specifically sized at 130.5mm, a common length for these Subaru engines, ensuring proper piston-to-valve clearance and geometry.

What sets these rods apart is the use of ARP 625+ material for the bolts. This is a premium alloy known for its exceptional strength and fatigue resistance, far exceeding standard ARP 2000 bolts. This means they can withstand the higher cylinder pressures and temperatures associated with boosted engines without stretching or failing. The rods themselves are forged from high-strength steel, then precision-machined to tight tolerances for a solid fit and consistent performance. This attention to detail is crucial for engine longevity, especially when pushing the limits of your EJ engine.

This kit includes everything you need to get these robust connecting rods installed. You'll find the rods, the ARP 625+ bolts, and the necessary nuts. It's a complete package for rebuilding or upgrading the bottom end of your Subaru's boxer engine. Make sure to follow the manufacturer's installation instructions carefully, especially regarding bearing clearances and torque specifications, to ensure optimal performance and durability.
