Mammoth Split 16 Beadlock Wheel. Mammoth's Split 16 Beadlock Wheel features a military inspired 8-spoke design with a inner ring that creates 16 individual windows. The simulated bead lock bolts around the outer lip adds to the wheels rugged good looks. A branded Mammoth center cap is included. This Mammoth Wheel is perfectly suited for street and off-road applications.
Satin Black Finish with Polished Lip. This Wheel is completed in a high quality, satin black finish with a polished lip for an impressive contrast in appearance that everyone will envy. For added protection and good looks, this Wheel features a durable clear coat that is tough enough to stand up against the hazards of everyday driving - including road chips and pitting.
One-Piece Cast Aluminum Construction. Mammoth's One-Piece aluminum Wheels are manufactured using gravity casting. Gravity casting is the process of pouring a molten aluminum alloy into a wheel mold or form utilizing the earth's own gravity to help fill the mold. The result is a strong, durable wheel that has the same good looks as a more expensive wheel, at a fraction of the price.
Application. This Mammoth Split 16 Beadlock Satin Black with Polished Lip Wheel; 18x9; -6mm Offset; 5 x 127mm (5 x 5-Inch) Bolt Pattern is designed to fit 2018-2025 Jeep Wrangler JL models. Sold individually.
Mounting & Balancing ExtremeTerrain offers professional mounting and balancing on all wheels and tires when purchased together on the same order. This will allow you to swap out your old wheels for your new set when they arrive.
What is TPMS? The Tire Pressure Monitoring System (TPMS for short) is a factory installed safety feature on all 2007 and newer Jeep Wrangler that alerts you when your tire pressure drops to an unsafe limit.
How do I keep my TPMS feature? Aftermarket wheels do not come with TPMS sensors. However, if you select 'Add TPMS Sensor’ and your specific year range from the options listed above, we'll install the TPMS Sensors in your new wheels!
For more Information, check out TPMS Sensor Kits in detail.

Mammoth wheels
Awesome experience. Be warned Walmart will mount and balance but won’t install on vehicle if they’re not factory size tires. Installed myself but really didn’t want to because I’m an old fart.

Makes an aggressive look
Perfect fit. Quality part. Makes a wider footprint. Tires look great. Stick out the wheel wells about 1 1/2”!

Review shared from Mammoth 2-Inch Billet Wheel Spacers; Black (18-25 Jeep Wrangler JL)
Exceeded My Expectations
I was very hesitant at first to buy spacers in general, but a few Jeep forums I follow recommended these 2-Inch spacer from Extreme Terrain. These things were real deal, fit perfect and gave me the look I wanted. Thank you Extreme Terrain...

Review shared from Mammoth 1.75-Inch Billet Wheel Spacers; Black (18-25 Jeep Wrangler JL)
Nice aggressive look
Fit perfect. Remember to remove the plastic guide ring around bearing hole and place on spacers. Use thread lock and torque down. Wider stance looks aggressive but not too wide. Takes about 10 minutes per wheel.
