*Note: An aftermarket steering column is required for proper steering system fitment and function. Steering shaft kit 220522 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 Josh to order a column so you get the correct part number.
**All frame orders will have a $900 crating fee plus truck freight shipping added on at the time of processing. Speedtech has several options for shipping and is dedicated to provide you with the best quality service and lowest cost available to your area. To save on shipping costs we recommend your chassis be delivered to a shipping terminal or a business with a loading dock and/or forklift access.
