West Coast Accessories W55125S 12 mm × 1.25 Open Spline Lug Nut
Installer Kit (6-lug)
Product Description:
Upgrade your wheel-hardware setup with the W55125S installation kit from West Coast Accessories—designed for precision, durability and clean professional results. This kit is tailored for 12 mm × 1.25 thread spline-type lug nuts in applications where proper installation is key to performance and appearance.
Why choose this kit?
-
Purpose-built for 12 mm × 1.25 thread lug nuts — ideal for vehicles (often import/performance) that utilize this finer metric specification.
-
Works with spline / open style lug nuts — ensuring you have the right tool to avoid damage to the lug or wheel seats during install.
-
Designed with ease of installation in mind — helps you maintain correct torque, avoid rounding off spline lugs, and get a secure, factory‐quality fit.
-
Offered by Speedzone Performance LLC — as an aftermarket performance specialist we know the small components like lug-nuts and install kits matter just as much as big upgrades.
Key Features:
-
Compatible specifically with 12 mm × 1.25 thread size and open-spline lug nut design.
-
Includes the proper socket adaptor or tool that fits spline-style lugs (verify contents on kit).
-
Designed for 6-lug wheel hubs (check your vehicle has a 6-lug pattern or that you’re using compatible wheels).
-
Helps eliminate installation mistakes: wrong socket type, over-/under-torque, mismatched hardware.
-
Ensures better long-term reliability: correct seating and torque mean less chance of loosening, corrosion or wear.
Fitment & Installation Notes:
-
Confirm your vehicle’s wheel stud thread is 12 mm × 1.25 and you have (or will install) spline-type/open-style lug nuts matched to this kit.
-
Confirm your wheel hub is a 6-lug pattern (many import/performance cars use 5-lug; some trucks/SUVs use different sizes) and that the wheel manufacturer allows this type of hardware.
-
Clean the wheel seat area and studs before install; apply proper torque per vehicle/manufacturer spec (don’t rely on “hand-tight” or generic numbers).
-
Store the install kit socket tool with your vehicle or service kit so future wheel changes use the correct tool—and avoid stripping the lug surfaces.
