*Note: An aftermarket steering column is required for proper steering system fitment and function. Steering shaft kit 220522 (order below) is for an Ididit steering column. Because of differences in design they will not fit other aftermarket columns.
All ExtReme shock and sway bar packages will be customized to your specific vehicle. This can be done as you order over the phone, or for online orders our friendly sales staff will contact you to review options when the order is processed.
Factory steering columns may not be the right length for the correct steering shaft angle and may not work with the ExtReme suspension components. We recommend an Ididit steering column for best results. Please speak to your sales rep to order a column from us or to obtain the correct part number.
Black powder coating adds on $800, while some other colors may be more. Click the box below to add coating and your sales rep will discuss color options and pricing with you. If necessary the coating cost will be adjusted when the order is processed.
