MIKKUPPA M14x1.5 Lug Nuts 32-Piece Chrome — OEM-Style Closed-End Bulge Nuts, 7/8" Hex

MIKKUPPA M14x1.5 32-piece chrome lug nuts are a direct-fit OEM-style replacement designed for select Chevy, GMC and Ram 6- and 8-lug factory wheels.

These lug nuts deliver a factory-compatible fit and a polished finish for 2008–2024 heavy-duty Silverado and Sierra 2500/3500 models and 2012–2024 Ram 2500/3500 trucks. Built as one-piece, closed-end bulge nuts with a 60° conical seat and 7/8" (22mm) hex, they replicate the original hardware’s dimensions while offering corrosion resistance from a durable chrome plating. The set includes 32 lug nuts so you have a full complement for dual-wheel or spare-wheel arrangements.

Will these lug nuts fit my Chevy, GMC, or Ram truck?

Yes — these M14x1.5 lug nuts are engineered to match the OEM thread pitch and seating style common to many factory heavy-duty wheels. They replace several original part numbers and are intended for both 6- and 8-lug wheel patterns used on the listed models.

• Thread: M14 x 1.5 metric pitch
• Seat type: 60° conical (bulge style)
• Hex size: 7/8" (22mm) for standard sockets
• Length: approximately 1.75" (45 mm) closed-end body

How does the construction affect durability and appearance?

The lug nuts are manufactured as a single solid piece rather than a two-part assembly, reducing the risk of cracking and separation under load. A chrome-plated surface improves resistance to rust and provides a bright, factory-like appearance that complements polished wheels.

• One-piece design prevents joint failure common in two-piece nuts
• Closed-end body blocks contaminants from entering the stud area
• Chrome finish resists oxidation and keeps wheels looking clean
• Tested against salt spray for enhanced corrosion protection

What tools and torque should I use to install these lug nuts?

Use a 7/8" (22mm) socket or compatible impact socket designed for lug nuts. Follow the vehicle manufacturer’s recommended torque specification and tightening sequence to ensure safe installation and even clamping across the wheel.

• Socket size: 7/8" (22 mm) — hex drive compatibility
• Recommend: use torque wrench for final torque to OE spec
• Always tighten in a star or crisscross pattern for wheel clamping
• Do not exceed vehicle OEM torque values to avoid stud damage

What’s included and what OEM part numbers does it replace?

This package contains 32 chrome lug nuts to cover complete wheel sets and extras for dual-wheel setups. They are designed as replacements for a range of GM and Chrysler part numbers so installers can swap them in without modifying wheels or studs.

• Quantity: 32 lug nuts — enough for dual-rear-wheel configurations
• Replaces common OEM part numbers such as GM 9596070 and several 611-xxx variants
• Closed-end bulge style matches factory wheel seats
• Color: chrome for a factory-polished look
