Purpose-Built Lug Nuts for Ram Truck Wheel Applications Requiring Shank Seat Fitment
The Race Star RST601-1425-10 is a 10-piece lug nut kit designed specifically for Ram truck applications using a 14mm x 1.5 thread pitch with a shank seat style. Race Star engineers the RST601-1425-10 with a 1.38-inch shank length to provide secure engagement in Ram truck wheel designs that use a shank seat rather than the more common tapered or ball seat. The 7/8-inch open end hex allows use with both standard and deep well sockets. The set includes 10 lug nuts, which covers two wheels on a five-lug configuration or serves as a spare supply for multi-axle setups. Race Star manufactures the RST601-1425-10 from steel with a chrome finish for a clean, durable appearance that holds up to the heat and weather exposure typical in truck applications.

Frequently Asked Questions
What vehicles does the RST601-1425-10 fit?
The RST601-1425-10 is designed for Ram trucks using a 14mm x 1.5 thread pitch with a shank seat wheel design. Always verify your truck's wheel seat type and thread pitch before ordering, as using the wrong seat style can result in improper clamping.
What is a shank seat lug nut and why does my Ram need it?
A shank seat lug nut uses a cylindrical flange that engages a recessed pocket in the wheel rather than a tapered or ball seat. Ram truck wheels designed for shank seat lug nuts require this specific style for proper load distribution. Using the wrong seat type will not properly center or clamp the wheel.
What size socket do I need for the RST601-1425-10?
The RST601-1425-10 uses a 7/8-inch open end hex head. A 7/8-inch (22mm) socket is required for installation and removal.
Are 10 lug nuts enough for my truck?
The 10-piece RST601-1425-10 kit covers two wheels on a 5-lug vehicle. For a full vehicle set on a standard 5-lug truck, you would need two kits (20 nuts). Race Star also offers a 20-pack variant for full-vehicle coverage.
What is the torque specification for the RST601-1425-10?
Follow your Ram truck's factory torque specification for wheel fasteners, typically in the range of 130-140 ft-lbs for heavy-duty applications. Always verify against your specific model year's service manual.
Are Race Star lug nuts safe for daily street use?
Yes. Race Star lug nuts are designed for both street and racing applications. Inspect periodically for corrosion, thread damage, or wear and replace as needed.
Can I use the RST601-1425-10 with aftermarket Ram wheels?
Only if the aftermarket wheels use a shank seat design matching the RST601-1425-10 seat style. Aftermarket wheels vary in seat type, so confirm the wheel manufacturer's specified lug nut seat style before ordering.
Is there a 20-pack version available?
Yes. Race Star offers a 20-pack version (RST601-1425-20) for full four-wheel coverage on a 5-lug vehicle, which is the recommended purchase for a complete set on a Ram truck.
Installation Instructions
- Confirm the RST601-1425-10 thread (14mm x 1.5) and shank seat style match your Ram truck wheel and hub stud specifications.
- Clean the wheel studs and lug nut threads of any debris or corrosion before installation.
- Thread the lug nuts onto the wheel studs by hand, ensuring they seat correctly in the wheel's shank seat recesses without cross-threading.
- Using a 7/8-inch (22mm) socket and torque wrench, tighten in a star pattern to your Ram truck's factory torque specification.
- Recheck torque after the first 50 miles of driving following wheel installation.
