Lug Nuts & Wheel Locks

Switching to aftermarket wheels or running heavier off-road tires usually means upgrading your factory lug nuts and adding wheel locks to protect your investment. Our lug nut and wheel lock lineup covers the most common thread pitches across Canadian trucks — 14x1.5 for newer Ford, Chevy, GMC, and Ram heavy-duty trucks, 14x2.0 for older Super Duty and HD models, and 12x1.5 for Toyota Tacoma, Tundra, and select half-ton applications. Every set is sized to your wheel's seat type, whether that's conical (acorn), mag-style flat seat, or shank-style for OEM-fit applications.

Lug Nut Styles, Wheel Lock Brands, and Aftermarket Wheel Fitments

We stock spline drive lug nuts in black and chrome, acorn lug nuts in 14x1.5 and 12x1.5, spike lug nuts for lifted trucks, open-end and closed-end designs, and full lug nut sets in matching finishes. For wheel security, we carry McGard wheel locks for trucks, Gorilla lug nut and wheel lock sets, and complete keyed-alike kits that pair four locks with matching lug nuts. Pair your new lug nuts with aftermarket wheels and tires from the Tires collection, or grab matching Wheel Spacers to fine-tune offset and stance.

Frequently Asked Questions

How do I know what size lug nuts fit my truck?

Lug nut size is determined by three factors — thread pitch, seat type, and overall length. Most modern Ford, Chevy, GMC, and Ram heavy-duty trucks use a 14x1.5 thread pitch, while Toyota Tacoma, Tundra, and select half-ton applications use 12x1.5. Older Super Duty and HD models often use 14x2.0. Seat type matches your wheel's lug hole — conical (acorn) for most aftermarket and OEM truck wheels, mag-style flat seat for some specialty wheels. Check your owner's manual or measure an existing factory lug nut to confirm before ordering.

What is the difference between spline drive and acorn lug nuts?

Acorn lug nuts use a standard hex socket — typically 19mm, 21mm, or 22mm — and require a regular lug wrench or impact socket to install and remove. Spline drive lug nuts use a smaller, splined head and require a matching spline drive key socket included with the set. Spline drive lug nuts have a slimmer profile, which is critical for aftermarket wheels with narrow lug holes that won't accept standard acorn nuts. They also offer a small theft-deterrent benefit since the spline key is unique to that set.

Do I need wheel locks on my truck to prevent theft?

Wheel locks are highly recommended for any truck with aftermarket wheels worth more than a few hundred dollars. A typical wheel lock set replaces one lug nut per wheel with a uniquely-keyed lock that requires a matching key socket to remove — without the key, a thief can't unbolt the wheel. McGard wheel locks for trucks and Gorilla wheel lock sets are the two most trusted brands and come keyed-alike across all four wheels for single-key convenience.

What is the difference between open end and closed end lug nuts?

Open-end lug nuts have a hollow tip that exposes the wheel stud thread above the nut — useful for trucks running longer studs, aftermarket wheels with deeper lug holes, or when stud length varies across vehicles. Closed-end (acorn) lug nuts have a sealed tip that covers the stud completely, providing a cleaner cosmetic finish and protecting the stud thread from rust, salt, and road debris. For Canadian winter driving, closed-end lug nuts offer better long-term thread protection.

Do you need new lug nuts when switching to aftermarket wheels?

In most cases, yes. Aftermarket wheels often have a different lug seat type, narrower lug holes, or different thread engagement requirements than factory wheels. Running factory acorn-style lug nuts on aftermarket wheels with mag-seats — or vice versa — can lead to loose wheels, damaged hardware, or wheel separation. Always confirm the seat type and minimum thread engagement specified by the wheel manufacturer, then match a lug nut set to those specs.

Do black lug nuts last as long as chrome lug nuts?

Quality black lug nuts use either a powder-coated or zinc-plated black finish that holds up well against road salt, brake dust, and weather — comparable to chrome over the same usage period. Lower-end black-coated lug nuts can chip or fade if struck repeatedly with poorly-fitted sockets, so always use the correct socket size and avoid impact gun overtorquing. For Canadian winters, sealed closed-end black lug nuts paired with anti-seize on the threads will outlast most factory hardware.
