Hub Caps, Wheel Simulators and Key Fob Covers

Wheel simulators: size, lug count and mounting

Wheel simulators dress up the rear wheels of dually pickups and the steel wheels of heavier trucks. Titles give the wheel diameter, such as 17 inches for dually pickups or 19.5 inches for 10-lug heavier trucks, and the year range. Count the lug nuts on your wheel and measure the diameter before ordering. Stainless steel resists rust, and simulators are sold in sets for a stated number of wheels.

Key fob covers and shells: count the buttons

A silicone cover slips over a working fob to protect it, while a shell replaces a cracked case and means moving the circuit board, battery and transponder chip into the new housing. Match the button count, usually four or five, plus the shape and model-year range. An uncut blade still has to be cut to your key code, and a shell does not change the programming of the original electronics.

Questions about Hub Caps, Wheel Simulators and Key Fob Covers

Will a new key fob shell need reprogramming?

Usually not, because the original electronics move into the new shell. The chip and circuit board hold the programming, so handle them gently and keep the battery contacts clean.

How do I know if I need 8-lug or 10-lug wheel simulators?

Count the lug nuts on the wheel and measure the wheel diameter. Wheel simulators are made for a specific lug count and wheel style, so a set made for another layout will not mount properly.

Are hub caps universal?

No. They are matched by wheel diameter and the clip or retention pattern, and sometimes by vehicle. Measure the wheel and check the listing's stated size and fitment.
