US Mags 15" x 7" Indy Wheel | Chrome | 5 x 5.5 Bolt Pattern
Vintage Baja Style. Built for Broncos.
Bring classic off-road style to your Bronco with the legendary US Mags Indy Wheel. The original wheel that launched the US Mags brand, the Indy is steeped in history — with roots in the rugged Baja racing circuits where Broncos first proved their worth. Crafted from tough one-piece cast aluminum, this 15x7 wheel delivers the strength you need for off-road adventures with vintage-inspired looks that turn heads on the street.
With its high-luster polished finish and aggressive stance, the Indy pairs perfectly with 66–77 Broncos running larger tires and mild lifts. The 5x5.5 bolt pattern and 4.25" center bore make it a direct fit for classic Broncos and classic Ford 1/2-ton trucks alike. Whether you're building a showpiece or a trail-ready rig, the Indy wheel delivers iconic style and performance that lasts.
Legendary Design:
The original US Mags wheel, born from Baja racing heritage
Timeless Indy styling for a classic Bronco or Ford truck build
High-Luster Chrome Finish:
Polished to perfection for a show-quality look
Durable finish for lasting shine on- or off-road
Heavy Duty Construction:
One-piece cast aluminum wheel for strength and durability
Designed to handle the demands of off-road use
IMPORTANT NOTE: Because of the 3.75" back spacing of this wheel it will not work with 1976-1977 Bronco disc brake knuckles. That also means if you have converted an earlier Dana 44 to disc brake using the 76-77 parts it will not work. If you want to use our 1.25" billet wheel spacers that would work. The problem and the way to identify a 76-77 Bronco steering knuckle is where the tie rods attach to the knuckle instead of the knuckle being straight it arches towards the wheels.

Asked by tony, December 25, 2021
Q: if these 15x7 wheels with a 3.75 backspace fit a 76-77 bronco with a 1/4 spacer, then shouldn't a 15x8 wheel with a 4 backspace fit a 76-77 bronco with a 1/2 spacer?
Answered by ☆ sales - December 27, 2021
A: Yes, with the 76-77 knuckles, you want to end up with about 3.5. of backspacing to clear the knuckles and steering components.
