Overview
Rancho describes the RS9000XL as the first nine-position manually adjustable ride control series in the off-road market. This listing is for one shock, cross-referenced to a long run of original part numbers.
The attraction is a ride that can be tuned by hand for on-road, off-road or towing use. The listing is thin on the rest, with no vehicle list, no length and a material row that reads polyurethane.
Who it's for
A truck or SUV owner who wants to adjust ride firmness between uses can match the part number against the list. Buyers who need two shocks, or published travel lengths, should confirm the quantity and size before ordering.
Pros and cons
- Long cross-reference list
- On-road and off-road use
- Towing use named
- Vehicle fit not listed
- Extended length not listed
- Sold as a single shock
- Material row reads polyurethane
Performance notes
Turning the adjuster changes the valving, so the shock resists movement more or less across its nine positions. The listing gives no damping figures, so the firmness at each setting is not described here.
