Gorilla 6Lug 14-1.50 Spline Wheel Lugs - Black Kit

In this review the Gorilla 6Lug 14-1.50 Spline Wheel Lugs kit is evaluated for drivers who need a reliable set of lug nuts for aftermarket wheels or heavy passenger trucks. The bottom line: this kit is for shoppers who want a complete package that fits common 14mm x 1.50 threaded studs and offers a combination of practical size and fit. The review focuses on real-world fit, finish, and the included accessories to determine whether this lug nut kit is a sensible upgrade or replacement for factory hardware.

Key Features

• Seat Type Conical: The conical seat ensures a secure, centered fit on most aftermarket and factory wheel holes to reduce misalignment during installation.
• Thread Size 14mm x 1.50: This common thread pitch provides compatibility with many modern passenger trucks and SUVs that use 14mm studs.
• Dimensions: With a 2' overall length and a 23mm outside diameter, the lugs provide substantial engagement and a robust seating area for torque transfer.
• Dual Hex Sizes: The dual hex design (13/16' or 21mm and 7/8') lets a mechanic use common sockets without needing specialty tools in many garages.
• Complete Kit: The package includes 24 lugs plus one 1378SD-KEY, so it covers a full 6-lug wheel set with spares and the key for spline-style security.

Who It's For

The Gorilla lug nut kit is best for owners of 6-lug trucks and SUVs who want a direct-fit replacement or a reliable set for aftermarket wheels. Mechanics and DIYers who value having the correct key and extra pieces included will appreciate that the kit arrives ready to install on a set of three axles or with spares for seasonal wheel changes.

Those who should look elsewhere are owners of vehicles that do not use 14mm x 1.50 threads or who need a tapered seat other than conical; also, drivers seeking decorative or chrome-plated styling beyond a black finish may prefer a different aesthetic option.

Pros & Cons

Pros

• Quality construction and finish that customers say hold up and look good on both factory and aftermarket wheels.
• Complete kit with 24 lugs and the included 1378SD-KEY removes the need to source additional parts for a full wheel set.
• Dual hex sizing and common thread make installation straightforward with standard hand tools.
• Dimensions deliver solid engagement and a secure seat to help maintain lug torque under normal driving conditions.

Cons

• The kit is specific to 14mm x 1.50 thread applications, so it is not universal for all vehicles.
• Finish and theoretical rust resistance noted by customers are positive, but long-term corrosion resistance will depend on local climate and maintenance.
