SneedSpeed R56 N14 & N18 4340 Forged Connecting Rod Set

Purpose-built for MINI performance. Engineered for strength, reduced weight, and direct-fit installation.

Not all forged connecting rods are created equal.

The SneedSpeed 4340 Forged Connecting Rod Set was designed by Chris Sneed using more than 20 years of MINI engine-building and racing experience. Rather than simply producing another heavy-duty connecting rod, Chris focused on four critical factors: strength, weight, fitment, and friction reduction.

The result is a purpose-built forged connecting rod designed to support high-horsepower N14 and N18 engines without unnecessary weight or costly block modifications.

Designed by Chris Sneed. Built for the MINI.

One of the challenges with aftermarket connecting rods is clearance inside the N14 and N18 engine blocks. Some competing rod designs require additional block clearancing during installation.

SneedSpeed rods were specifically engineered to clear the inside of the factory engine block without grinding or machining for connecting rod clearance.

That means less machine work, fewer installation complications, and a connecting rod designed around the engine it's actually going into.

4340 Forged Steel — Strength Without Unnecessary Weight

Bigger and heavier doesn't automatically mean better.

SneedSpeed rods are manufactured from 4340 forged alloy steel, providing the strength and fatigue resistance required for high-cylinder-pressure turbocharged engines.

Chris designed these rods to reduce unnecessary mass while retaining the strength expected from heavier forged connecting rods.

Reducing reciprocating weight helps decrease inertial loading on the rotating assembly, particularly at elevated engine speeds.

The goal wasn't to build the heaviest rod on the market. It was to build a strong, lightweight rod specifically for the MINI engine.

Low-Friction Bronze Wrist Pin Bushings

Every SneedSpeed forged connecting rod features a self-lubricating, low-friction bronze-alloy wrist pin bushing, engineered to improve wrist pin operation under demanding engine conditions.

The bronze-alloy bushing provides a durable bearing surface designed to retain an oil film, reduce friction, and help control heat generation at the wrist pin.

This is particularly important in high-boost and high-RPM engines, where wrist pin loading and temperatures increase significantly.

Less friction. Better wear resistance. Improved durability under load.

High-Strength 8740 Chrome-Moly Rod Bolts

Connecting rod strength is only as good as the fasteners holding the big end together.

SneedSpeed rods include high-strength 8740 chrome-moly connecting rod bolts, designed to maintain secure clamping under the demanding tensile and inertial loads generated by high-performance engines.

These performance-grade fasteners provide the strength and fatigue resistance needed for aggressive turbocharged applications and elevated engine speeds.

Built for Serious MINI Performance

Whether you're building a responsive street engine, a high-boost turbocharged MINI, or a dedicated competition engine, connecting rod selection is critical to bottom-end reliability.

SneedSpeed forged rods are an excellent choice for:

• MINI Cooper S and JCW performance engine builds

• Upgraded turbocharger applications

• Forged-piston engine combinations

• High-RPM track and endurance racing

• Street, Super Sport, and Race engine builds

Built from Racing. Proven by Results.

SneedSpeed connecting rods aren't simply another catalog part with our name on the box.

They're the result of Chris Sneed's experience building, developing, and racing MINI engines through more than 20 years of competition, including three championships, over 100 race wins, and a 24-hour endurance victory.

If we wouldn't run it, we don't sell it.
