Hey there, fellow gearheads! If you're on the hunt for some seriously tough axles, let me tell you about these USA Standard Gear axles. These bad boys are built to last, using some pretty impressive manufacturing tech right here in the USA. They’re not just any axles; they’re designed to handle the rough stuff, whether you're hitting the trails or just need something reliable for your truck.

  • They come with a beefy 35 spline inner and a 30 spline outer, which means they’re ready to take on some serious torque.
  • These axles fit the Dana Spicer 60 found in GM trucks from 1977 to 1991, so if you’ve got one of those, you’re in luck!
  • Included in the kit are inner and outer 4340 Chromoly axles along with Yukon Super Joints—these joints are tough as nails, giving you that extra peace of mind on those bumpy rides.

And you know what’s great? They come with a 5-year warranty against manufacturer defects. That’s how confident they are in their product. Trust me, you’ll want to have these under your rig if you’re serious about off-roading or just want to beef up your truck’s performance.

Just to keep it real, if you’re driving a GMC C/K 3500 from 1986 or a GMC V3500 from 1987, this axle kit is a perfect fit for you. It’s designed specifically for those models, so you won’t run into any surprises. You’ll be clearing those 33s with ease, and that’s always a win when you’re looking to upgrade your stance.
