Strange Oval premium torsion bars are designed to satisfy the most demanding Modified racer. Part of what puts Strange Oval ahead of the competition is the manufacturing process and innovation. The torsion bar rate (in-lbs) depends on the effective length of the bar, as well as the diameter of the bar. The rate of the given bar will also depend on whether the bar is solid or gun-drilled. Strange Oval torsion bars are gun-drilled with a 7/16-inch i.d. hole. In order to achieve the same torsional rate as solid bars, the effective diameter is increased, which gives the bar higher mechanical strength compared to its solid counterpart. To further increase strength, Strange Oval maximizes the effective length of its bars by shortening the splined end and bushing area to a combined length of 2 inches on each side. Maximizing the effective length allows Strange Oval to make the o.d. slightly larger, thus increasing the bar strength further. For example using a 12-inch arm; while a normal bar may measure 0.950-inch in diameter and have a bar rate of 266 lb/inch, the Strange Oval bar measures 0.961-inch in diameter and has the same bar rate (266 in-lbs), but is also lighter because it's gun-drilled and more reactive. This coupled with Strange Oval's proprietary heat treat, straightening methods, and shot peening yields the highest strength bars on the market. That's why Brett Hearn, Kenny Tremont and other top racers and builders depend on Strange Oval torsion bars.
