Six New Ratios Satisfy a Wide Range of Demands On- and Off-Road

Alloy USA Ring & Pinion Set for Jeep JK Wrangler Suwanee, Ga. (May 6, 2014) – Alloy USA®, a manufacturer of performance drivetrain products, including gears and high-strength axle shafts, has announced the availability of a wide range of ring and pinion sets for Jeep® JK Wranglers (2007 – 2014).

Available in 3.73, 4.10, 4.56, 4.88, 5.13 and 5.38 ratios, Alloy USA’s gear sets are made to last. Each set is constructed from high quality 8620 steel forgings and uses Gleason gear cutting technology for unsurpassed precision.

“From axle shafts, steering and suspension, and differential covers, Alloy USA really focuses on restored performance and increased efficiency,” said Henk Van Dongen, Director of Marketing at Omix-ADA.

Alloy USA now offers affordable high strength gear sets in all the popular ratios to satisfy everyone’s gearing needs. Oversized tires require higher ring and pinion ratios to restore performance.

“Changing ring and pinion gear sets compensates for larger tires and restores performance,” said Dave Logan, Product Manager at Omix-ADA. “That’s one of the many reasons Alloy USA plays a huge part in showcasing these products and what they can do.”
