Our Forged Mustang II Spindles Won’t Leave You Stranded

The venerable Mustang II IFS has been a popular upgrade for straight axle hot rods and pickup trucks for decades. What started out as a custom fabricated weld in solution using the stock Mustang 2 frontend has melded into a complete industry of custom bolt in and weld in Mustang II IFS suspension kit Shop Mustang II Crossmembers that are specific to many popular applications, including hot rods, pickups, and muscle cars. The original Mustang 2 spindles (and Pinto/Bobcat) are cast pieces. While you can still find original Mustang II spindles, and replacement cast Mustang 2 spindles are available, upgrading to forged Mustang II spindles is your best solution.

Forged Mustang II spindles are hot forged under pressure to their final shape and then surfaces machined. This forging process maintains the metal’s grain structure for increased strength. Cast Mustang II spindles are made from a mold that molten steel is poured into, thus having less strength in critical areas due to the non-uniform grain structure. Cast Mustang II spindles have been known to fail, especially original Ford units, which is why we only offer forged spindles for your Mustang II installation. These spindles feature stock height pins, fully machined for stock bearings, ball joint taper, and disc brake caliper mounting. Pair with your favorite Shop Mustang II Disc Brake Kits and you’re ready for many years of trouble free driving. Also check out our Mustang 2 drop spindles, featuring a built in Mustang II 2-inch Drop Spindles, if you’re looking to go even lower with your ride height.
