CLUSTER steering wheel is a design rooted in classic style, leveled way up. Crafted from one thick solid piece of forged 6061-T6 aluminum. Features include a larger modern size oval Comfort Grip in 15 inch diameter, wrapped in premium leather front and back, without stitching.. Finishes can be taken with classic full polish, or have Ceramic Coatings color options added for a custom finish. Schott Steering Wheels also include some of our signature Cover-Loc Wheel Tech in the new Horn Button Cartridge, for a clever no fastener assembly. These new Steering Wheels fit GM early columns and popular aftermarket columns.
