What it does
Lift and leveling kits raise the vehicle for bigger tires and more clearance. 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
- Plan for an alignment and check what tire size the kit clears.
- Alignment: Always after a lift.
- Longer brake lines: Bigger lifts may need them.
- 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.
