Sposuit 24-piece M14x1.5 spline lug nut set is a direct-fit replacement for many Chevrolet trucks and SUVs, offering a hardened one-piece, closed-end design with black triple-plating for corrosion resistance.

If you need a full set of replacement lug nuts built to match factory fitment and improve longevity, this Sposuit kit supplies 24 spline-style lug nuts plus a heavy-duty socket. The pack is engineered for popular Chevy vehicles — including Silverado, Traverse, Colorado, Tahoe and Avalanche model years listed by the manufacturer — and is finished in a durable black coating for a refined look and added rust protection.

Which Chevy models and years will these lug nuts fit?

These spline lug nuts are produced for vehicles using M14x1.5 thread pitch and a 60° conical seat. Sposuit lists compatibility across many Chevrolet model years; always verify your wheel stud specifications and seat angle to ensure correct fitment before ordering.

• Designed for M14x1.5 threaded studs and 60° tapered seating.
• Compatible with various 1999–2024 Silverado 1500 models (verify wheel type).
• Also fits many 2009–2024 Traverse, 2015–2024 Colorado, 2001–2024 Tahoe, and 2007–2013 Avalanche variants.
• Confirm wheel manufacturer and year-specific details using the product images and your vehicle’s manual.

How strong and durable are these Sposuit lug nuts?

Sposuit produces these lug nuts using cold forging followed by heat treatment to increase material strength. A triple-layer black plating adds corrosion resistance, and the one-piece closed-end construction reduces the risk of cracking or moisture ingress.

• Cold-forged steel with heat treatment for improved tensile strength.
• Triple black plating reduces surface corrosion and maintains appearance.
• Closed-end, one-piece design limits internal rust and stress points.
• Factory testing and precision machining for consistent thread accuracy.

What are the exact dimensions and what’s included in the set?

The set contains 24 spline lug nuts made to M14x1.5 specifications and one heavy-duty socket for installation. Key dimensions are provided so you can confirm fitment: 50mm overall height, 19mm hex drive, and a 23mm width across the nut body.

• Quantity: 24 spline lug nuts plus one 2-inch (50mm) long heavy-duty socket.

How should I install and maintain these lug nuts?

Install these spline lug nuts using the included heavy-duty socket and a calibrated torque wrench. Follow your vehicle manufacturer’s torque specifications and periodically inspect the lug nuts for tightness and surface wear to maintain safety and appearance.

• Use the provided 19mm socket for proper engagement of the hex drive.
• Tighten to Chevrolet’s recommended torque setting with a torque wrench.
• Check lug nut torque after 50–100 miles following installation.
• Clean and inspect finish; reapply protective treatments if corrosion appears.

Who is this for: This Sposuit 24-piece lug nut kit is aimed at Chevrolet owners, DIY mechanics and professional shops needing a complete replacement set that balances factory-style fitment, improved corrosion resistance and a blacked-out look. Choose this kit if your vehicle uses M14x1.5 studs and you want a durable, one-piece closed-end nut solution for passenger trucks and SUVs; if uncertain, verify wheel seat type and thread pitch before purchase.
