What it does

Full air ride systems need a compressor, tank and controller. Worn suspension and steering parts show up as clunks, wandering, uneven tire wear and a vague feel; fresh parts restore control, and performance parts sharpen it.

Installation & tips

• Check whether the listing includes the compressor and controls, or if you need them separately.
• Management: Needed unless the listing says it is included.
• This part affects how the vehicle stops, steers or holds the road. If you are not sure how to fit it, have it installed or checked by a qualified mechanic.
