Product Overview

Callies - Ultra Enforcer - U17175  -  Chevrolet -  LSX  -  Connecting Rods

Callies Performance Products has introduced a new line of connecting rods for those racers pushing the limits of what is possible! Callies Ultra Enforcer rods are designed for boosted and very high horsepower applications. These rods are rated for 300 Horsepower per Cylinder.

Increased mass & pressure angle archers guarantee added wrist pin stability

Ultra connecting rods are made entirely in the U.S.A. Every Ultra connecting rod is produced from specially formulated Timken 4330V steel. This material is then precision forged in Michigan and fully machined in our Fostoria, Ohio facility.

Many geometric nuances have been incorporated into the design of Ultra connecting rods. These design features enhance the Ultra against specific loads and stresses which are applied to connecting rods subjected to high load, high RPM applications. Ultra connecting rods are fastened by high alloy cap screws made specifically for severe duty service by ARP Inc. Produced with rolled threads, these unique bolts offer improved thread engagement for a smoother more consistent net clamping load. To eliminate deformation and extrusion only AMS 642 bronze alloy is used within the wrist pin housing bore.

Ultra I-Beams are available in our standard weight version for extreme duty racing applications of popular Big Block Chevy, Small Block Chevy, Chevy LS, Big Block Ford, Small Block Ford, RY45, Ford Modular, Nissan GTR, Buick 3.8, as well as lightweight versions for select SBC configurations. For superior clamping, a bolt upgrade to MP 3.5 material is available for all Callies I-Beam connecting rods.
