Which vehicles and wheels will these lug nuts work with?

These lug nuts are designed for aftermarket wheels that require a 9/16-18 thread and a 60° conical seat. They are compatible with a long list of truck models when the wheel specifications match.

• Common compatible models: certain Ford F250/F350 (1988–1997), Dodge Ram 1500/2500/3500 (various years), Dodge Durango (2004–2009), Chrysler Aspen (2006–2009), Hummer H1 (1992–2006), Ram Chassis Cab (2013–2018), and Dodge Dakota (2005–2011).
• Fitment depends on wheel seat type and thread pitch — verify 9/16-18 thread and 60° conical seat before ordering.
• Intended for aftermarket wheels; may not fit factory wheels with different seat profiles.

How durable and secure are these one-piece spike lug nuts?

The SUCOSO spikes use a one-piece forged design and heat-treated high-strength steel to improve toughness and reduce failure points that appear in two-piece styles. A black electrophoretic coating boosts corrosion resistance while closed-end construction protects studs from dirt and moisture.

• One-piece construction reduces risk of separation or rust between components.
• Cold forging, heat treatment and CNC threading for consistent fit and strength.
• Closed-end design helps shield wheel studs and prolong hardware life.

What are the exact specifications and what’s included?

These lug nuts are full-length spiked pieces measuring approximately 4.4" (112 mm) overall with a 0.9" (23 mm) body width, and use a 3/4" (19 mm) hex for installation. The package supplies a full set and a matching installation tool.

• Thread pitch: 9/16-18; Seat type: 60° conical.
• Dimensions: length ~112 mm (4.4"), width ~23 mm (0.9"); hex size 3/4" (19 mm).
• Quantity: 32 lug nuts (closed end) plus one 3/4" hex socket key for hand installation.

How should these lug nuts be installed and maintained?

Install these nuts by hand using the supplied 3/4" socket or a torque wrench; avoid high-impact air tools to protect the finish and threads. Periodic inspection and light cleaning will maintain appearance and service life.

• Use hand wrench or torque wrench; avoid impact guns for final fitment.
• Check thread engagement and torque to wheel manufacturer specifications.
• If storing, keep in a dry place; clean road salt and grime to preserve the coating.
