Engineered for extreme competition, these billet steel H-beam rods are the backbone of our own Volvo B18 race engines. Designed for maximum strength and reduced reciprocating mass, these longer rods are built exclusively for use with our short-crown forged pistons.

Product Specs

• Design: Heavy-duty H-Beam profile for superior rigidity
• Material: High-tensile billet steel
• Compatibility: Volvo B18 engines (Race applications)
• Piston Fitment: Must be used with our short-crown forged pistons
• Big End Type: Sized for special high-performance bearings

Why Choose These Race Rods?

• Proven Pedigree: The exact same rods we trust in every one of our in-house B18 race builds.
• High-RPM Stability: The H-beam design provides an incredible strength-to-weight ratio, preventing rod stretch and failure at high revs.
• Optimised Geometry: Longer rod length improves the rod-stroke ratio for smoother power delivery and reduced side-loading

Critical Technical Requirements

• Crankshaft Modification: These rods will not fit a standard journal. The crankshaft big end journals must be ground to suit the required size.
• Specialised Bearings: Requires special big end bearings (available separately in our shop).
• Piston Compatibility: These will not work with standard Volvo pistons due to differences in compression height and Gudgeon pin diameter.

[Crankshaft big end journals must be ground to suit.]

[Billet steel H-beam connecting rods for Volvo B18 engines. These are a longer con rod only suitable for our short crown forged pistons.]

[We use these rods in all of our B18 Volvo race engines. The big end is sized to use a special bearing. The crankshaft must be ground to suit. Big end bearings are available separately in our shop.]
