RRW Spline Closed End Lug Nuts (12x1.5 ET) | Toyota / GX / Bronco / Ranger

The RRW Spline Closed End Lug Nuts (12×1.5 ET) are engineered to provide maximum strength, improved thread engagement, and enhanced wheel security when running aftermarket wheels. Featuring a narrow spline design, these lug nuts are ideal for RRW wheels with 29mm countersunk lug holes, ensuring proper seating and clean fitment.

Constructed from hardened cold-forged vanadium steel, these lugs are built to withstand off-road abuse while resisting corrosion, rust, and paint chipping. The closed-end design protects wheel studs and delivers a clean, finished appearance.

Why Use ET (Extended Thread) Lug Nuts?

Toyota platforms such as the Tacoma, 4Runner, and GX are known for having short factory wheel studs. When switching to aftermarket wheels with conical seating, thread engagement is reduced compared to OEM wheels.

ET lug nuts solve this issue by:

• Providing increased thread engagement
• Ensuring a snug, secure fit within the wheel lug hole
• Making the wheel lug-centric in addition to hub-centric
• Delivering OEM-level wheel securement and peace of mind

All RRW ET lug nuts are fully compatible with all RRW wheels.
