PAC Hollow Torsion Bar - 30" x 1-1/8" - .950" Diameter
There are significant differences between gundrilled, and solid torsion bars other than their weight. The hole in the center of gundrilled torsion bars creates two surfaces instead of one, allowing the bar to react differently than a solid bar to deflection. Gundrilled torsion bars have a faster spring rate than a solid torsion bar, which means they rebound, or spring back, quicker. The center diameter of a hollow torsion bar is adjusted to achieve the same spring rate as a solid bar. Therefore, no chassis adjustments need to be made when switching from solid to hollow bars. PAC gundrilled, and solid torsion bars all start the same way, as aircraft quality high alloy steel stock, and the gundrilled bars are drilled out using the same high performance equipment used to machine the barrels of fine rifles. Track conditions and chassis characteristics determine which type of bar is the best choice for your particular application.
A frequently asked question from our torsion bar customers is, "How long should a torsion bar last?". The answer lies in how close to the material's yield point the bar is used. The closer the stress exerted on the bar is to the yield point of the material, the shorter the life of the bar. Consistently take a bar past its yield point and the life starts to go out of the bar. a high quality bar will not lose it's spring rate, it simply will not be as responsive as it is designed to be. An analogy would be to compare torsion bars to valve springs that test OK but the engine will not perform at its peak. All PAC torsion bars are manufactured of the finest materials and to the closest tolerances to insure unsurpassed durability and reliability under racing conditionsPit Stop USA offers PAC Hollow Torsion Bar - 30" x 1-1/8" - .950" Diameter 30HW0950 at low everyday prices.
