dynofit 9/16-18 Spike Lug Nuts for Dodge Ram 1500 (2002–2010) — Black, 8-Pack, Closed-End

Dynofit 9/16-18 spike lug nuts are a set of eight cold-forged alloy replacement lug nuts designed to fit Dodge Ram 1500 (2002–2010) and other vehicles that use a 9/16-18 thread with a 60° conical seat.

These lug nuts combine a tall, closed-end spike profile with a durable black electrophoretic finish and a one-piece construction for reliable wheel attachment. Engineered for vehicles requiring a 9/16-18 thread and 60° seat, they ship with a matching 3/4" (19mm) socket key protected in pearl cotton and are salt-spray tested for extended corrosion resistance.

Will these fit my truck’s lug bolts or studs?

They fit wheels that accept lug nuts (not wheel bolts) with a 9/16-18 thread and a 60° conical seat. Confirm your original lug nut seat type and thread pitch before ordering to ensure compatibility.

• Fits Dodge Ram 1500 model years 2002–2010 (8-lug wheels requiring 9/16-18).
• Also compatible with many Ram 2500/3500 (1994–2010) and select older F-Series and Hummer H1 models listed by manufacturers.
• Requires conical 60° seat—measure or compare to an original lug nut.
• Not suitable for wheel bolts or different thread pitches.

How durable are these lug nuts against corrosion and wear?

Dynofit uses cold-forged alloy steel for strength and applies a black electrophoretic coating to resist rust and prevent surface peeling. The parts undergo an extended 120-hour salt spray test, exceeding many competitors’ standards, which helps them maintain appearance and function longer in harsh conditions.

• Cold-forged alloy steel core for improved toughness.
• Black electrophoretic paint for superior corrosion protection.
• 120-hour salt spray testing for extended environmental resistance.
• Closed-end design helps keep out moisture and contaminants.

What are the exact specifications and what’s included?

Each lug nut measures approximately 4.4 inches (112 mm) overall with a 0.9-inch (23 mm) diameter and a 9/16-18 thread pitch. The package includes eight closed-end spike lug nuts and one 3/4" (19 mm) socket key, all cushioned in pearl cotton for safe delivery.

How should I install and maintain these lug nuts?

Installation should be performed using the supplied 3/4" socket key and a hand wrench for final torque to protect threads and finish. Regular inspection and proper torque checking after first 50–100 miles of driving are advised to ensure seating and safety.

• Hand-tighten then torque to vehicle manufacturer specs with a torque wrench.
