Overall Assessment

Customers highlight our product's superior quality, particularly noting the excellent finish of the gear, resulting from the lapping process, which they regard as superior to Richmond gears. The product is seen as good value for money, with excellent fitment qualities such as no runout on ring gear. They praise its practicality for various uses, including installation in circle track cars. Its performance and reliability are acclaimed even under high horsepower (500hp) conditions. Commended by differential experts, it's the preferred choice over competing brands.

I'm looking for a "taller" ring and pinion set for a Ford 9" to increase gas mileage and reduce engine wear and tear on my '66 Ford T-Bird with a stock 390 engine. Now, with a factory 3.0 rear, it turns about 3,000+ rpm at 60 mph. Do you carry ratios such as 2.75 or less?
