KSP PERFORMANCE M14x1.5 Spike Lug Nuts 24pc Black — Bulge Acorn, Cold-Forged Alloy with 3/4" Socket Key

KSP PERFORMANCE M14x1.5 spike lug nuts are a 24-piece set of black, cold-forged alloy steel bulge acorn nuts with a closed end and a 3/4" (19mm) high-precision socket key, engineered to fit 14mm x 1.5 thread wheels on many full-size trucks and SUVs.

If you want to upgrade the look of your truck while maintaining factory-style fitment and reliable strength, these spike lug nuts deliver a bold style and OE-level performance. The one-piece, cold-forged alloy construction reduces the risk of cracking compared with two-piece designs, and the electrophoresis finish improves corrosion resistance for longer-lasting color and protection.

Will these lug nuts fit my Silverado, Sierra, or F-150?

These lug nuts are made for wheels with a M14 x 1.5 thread pitch and a 60° conical seat. They cover many common six-lug and five-lug applications across trucks and SUVs — but always verify your wheel’s thread pitch and seat type before purchase.

• Thread pitch: M14 x 1.5 (14mm x 1.5)
• Seat: 60° conical/bulge acorn style
• Examples: 1995+ Silverado/Sierra/Yukon/Tahoe/Suburban, 2015+ F-150/Expedition, 2019+ Wrangler JL/Gladiator JT, others

How strong and durable are these spike lug nuts?

The nuts are cold-forged from alloy steel in a one-piece construction to maximize tensile strength and reduce failure points common to two-piece designs. They undergo finishing via electrophoresis to improve rust resistance, and each set is produced and tested to meet or exceed OEM-style quality standards.

• Material: cold-forged alloy steel for higher strength
• Design: one-piece construction to resist cracking and loosening
• Finish: electrophoresis painting for corrosion protection

What are the size and kit contents included?

The kit includes 24 spike lug nuts sized for deep-lug applications and a single high-precision socket key for installation. Dimensions are provided so you can confirm clearance with aftermarket wheels and center caps prior to purchase.

How do these lug nuts affect installation and maintenance?

Installation uses the supplied 3/4" (19mm) socket bit, and the closed-end design helps protect threads from moisture and road debris. Proper torque with a calibrated torque wrench is recommended, and periodic inspection keeps fasteners secure and corrosion-free.
