Our Classic Tilt Columns are designed for non-airbag applications only. If you want an accessory, such as dimmer switch, this should be ordered with the column and we will install it for you. Designed to use the existing OEM 2" diameter mounting hole. Our standard shaft on classic columns is 1" DD. We can also make a 3/4"-36 or 1"-48 column to match your existing steering joint setup. Please specify in the comments area when ordering. All Flaming River columns are made from 304 grade stainless steel, in paintable mill finish OR polished to a high luster. They will never rust and are chemically clean and can be painted to match or highlight an interior with only minor preparation.
