1998-2002 Mercury Grand Marquis Wheel Spacer Fitment Guide

A wheel spacer keeps your 1998-2002 Mercury Grand Marquis's factory bolt pattern and pushes the wheel outward for a wider track — more stance, and clearance for larger tires, wheels, or brakes. To fit, a spacer has to match your bolt pattern and center bore, and it seats flush on the hub. Use the fit bar above to confirm your 1998-2002 Mercury Grand Marquis's exact specs before ordering.

Spacers and adapters are often confused. A wheel adapter changes the bolt pattern — it lets your Grand Marquis run wheels with a different lug pattern than the hub (and adds width like a spacer). Thread pitch is a separate question: a bolt-on spacer or adapter must use studs and lug nuts that match your vehicle's thread pitch, and if they differ the fix is the correct lug nuts, not an adapter. Never force a mismatched thread.

Frequently asked

Will these fit my 1998-2002 Mercury Grand Marquis exactly? Bolt pattern and center bore can vary by trim and model year even within the same generation — confirm your exact specs with the fit bar above or your vehicle's door-jamb/owner's-manual data before ordering.

Slip-on or bolt-on — what's the difference? Slip-on spacers have no studs of their own: they slide over your factory studs and reuse your original lug nuts, so longer studs are sometimes needed to keep safe thread engagement. Bolt-on spacers and adapters have pressed-in studs and bolt to the hub with their own lug nuts. Check each product's install-type spec.

Do I need new lug nuts or extended studs? Slip-on spacers may need extended studs to maintain minimum thread engagement. Bolt-on spacers and adapters include hub-side lug nuts; if their stud thread pitch differs from your vehicle's, matching lug nuts are required. Titan products are for off-road and competition use — always install with a torque wrench (never power tools) and re-torque after the first 25 miles.
