About Oliver Racing Parts

When engine builders demand connecting rods that can survive the brutal forces of high-horsepower racing, Oliver Racing Parts is a name that comes up again and again. Based in Charlevoix, Michigan, Oliver has spent decades earning the trust of professional engine builders and amateur racers alike by doing one thing exceptionally well: manufacturing world-class connecting rods entirely in the USA.

Every Oliver connecting rod begins with premium, mill-certified aircraft-quality E4340 AQ chromoly alloy steel — material that meets the demanding AMS 2301 cleanliness standard. From there, a proprietary two-stage heat treatment process optimizes stress relief and produces a 100% martensite grain structure, delivering a combination of strength and toughness that few competitors can match. The result is the kind of part that engine builders reach for when failure is simply not an option.

What truly distinguishes Oliver is their obsessive commitment to precision. Using Geometric Dimensioning and Tolerancing (GD&T) protocols, a Zeiss CMM, and a Sunnen SH4000 electro servo honing machine, every rod is manufactured against the same three datum reference points from start to finish. This climate-controlled, repeatable process ensures that each engine connecting rod that leaves the facility is dimensionally consistent — critical in high-RPM applications where even minute variances can cause catastrophic failures.

Oliver's exclusive "Parabolic Beam" I-beam design reduces beam stress while delivering one of the highest strength-to-weight ratios available in any connecting rod on the market today. Their product line spans applications from small block and big block Chevy platforms to LS-series engines, Ford small block, and even Duramax diesel — making their engine connecting rod sets a go-to solution for a remarkably wide range of builds.

It's no surprise that Oliver billet and forged steel rods have found their way into NASCAR Cup cars, NHRA drag racers, Bonneville land speed record vehicles, offshore powerboat racers, short track circle cars, and tractor pull machines. The brand's rod designs are continuously refined with direct feedback from the world's top engine builders — a development cycle that simply cannot be replicated overnight.

Complementing their rod lineup, Oliver also offers purpose-matched engine connecting rod bolts in premium alloy grades including ARP2000, L19, and ARP Custom Age 625+ — ensuring that the fastener holding the rod cap in place is engineered to the same uncompromising standard as the rod itself.

For engine builders who refuse to settle, Oliver Racing Parts represents a rare combination of American craftsmanship, aerospace-grade materials, and race-proven engineering. Whether you're building a weekend warrior or a championship-caliber race engine, Oliver rods are designed to go the distance.
