There are two types of intermediate shaft systems: DD or Splined. Either shafting is ideal for your steering system. Splined shafts allow a more precise adjustments. DD can only be phased 180° while splined shafts can be rotated fractionally. The advantage to DD, however, is that it can be cut to any length eliminating the need to premeasure. You will need to choose which shafting you will be using prior to ordering the universal joints, since one side accommodates the shaft. Manufactured using a pre-ground alloy steel for strength and cosmetics. Available with electroless nickel plating for corrosion resistance. Shafts are manufactured in 2" increments: 4"-36" lengths. Splined 2 inches on each side. This allows for up to 2 inches of total trim.Pit Stop USA offers Flaming River Steel Steering Shaft - 3/4" Diameter - 36-Spline Both Ends - Shaft Length - 8" FR1870-8 at low everyday prices.
