Frequently Asked Questions
Will Rancho RS66157B fit a different year or model?
Only the applications shown in the fitment table are supported. Match the exact year, make, model, trim, body style, and every manufacturer note before ordering.
Will I need an alignment after installation?
Yes. Any change to ride height or suspension geometry should be followed by a complete alignment plus tire, brake-line, steering, driveshaft, and suspension-clearance checks.
What tire size can I run with this kit?
Tire clearance depends on wheel width, offset, backspacing, body clearance, alignment, and vehicle load. Use the manufacturer recommendation only as a starting point and verify full steering and suspension travel.
Installation
Follow the current Rancho instructions and vehicle service information for the exact part number. Support the vehicle safely, confirm the suspension position and lift range, inspect mounts and bushings, use the specified hardware and torque values, verify brake-line, steering, tire, driveshaft, and suspension clearance through full travel, complete an alignment when geometry changes, and recheck all fasteners after initial use.
