YHTAUTO Wheel Adapters convert a 4x108 hub to accept 4x100 wheels, adding one inch of offset for extra clearance and a wider track. Drivers seeking a tougher stance and room for larger brakes or calipers will welcome the gained space and improved stability. Are these adapters the right upgrade for the Ford and Mercury models listed?
⚡ At a Glance
- • Fit and Compatibility: Adapts vehicles with a 4x108 mm bolt pattern to wheels drilled 4x100 mm; requires a 78.1 mm centre bore match and correct lug fitment.
- • Best for: Owners of compatible Ford and Mercury models who need extra clearance or want to fit 4x100 wheels
- • Not ideal for: Vehicles whose bolt pattern or centre bore do not match or where spacers are not permitted
Four lug-centric adapters with a 1 inch thickness and M12x1.5 studs. Recommended torque is 70-80 FT/LBS with 12.9 grade studs for high clamping strength.
Secure Wheel Clamping – With M12x1.5 studs and 12.9 grade bolts
Lug-centric design uses the 78.1 mm centre bore to locate the wheel on the hub while M12x1.5 studs deliver a direct threaded connection. Grade 12.9 studs are a high tensile specification intended to tolerate heavier clamping loads.
Strong, consistent clamping reduces the chance of loosening under load and improves confidence for heavier wheels or frequent use. Regular torque checks and the recommended torque range maintain long-term security.
Extra Clearance and Track Width – Thanks to 1 inch spacer thickness
One inch of spacing moves the wheel laterally by that distance, creating additional clearance between wheel and caliper or suspension components. The added offset effectively increases track width.
Provides the clearance needed for larger brakes or aftermarket calipers and gives a wider stance for improved road stability. Ideal when fitting wider tyres or running a mild lift setup.
Vehicle-Specific Fitment – With a 4x108 to 4x100 bolt pattern conversion
Adapters convert the vehicle hub bolt pattern (4x108 mm) to accept wheels drilled at 4x100 mm, and rely on a 78.1 mm centre bore for proper centring. Compatibility listings cover many Ford and Mercury years and models.
Suitable for owners of the listed Ford and Mercury models who want to reuse 4x100 wheels without machining or custom hubs. Always verify model fitment using the seller’s compatibility guide or the Amazon garage tool.
