Ultimate Alignment Pins

$44.99

Ultimate Alignment Pins

  • Upgraded stainless steel alignment pins that thread together.
  • Fitment: 1999 to current GM Trucks/SUV's - 1500, 2500 and 3500 models.
  • Our pins are designed to bolt to the frame, no modifications needed.
  • Factory pins fall out over time and other aftermarket pins press-in, but eventually fall out as well.
  • These pins will help your control arms stay aligned which will help the longevity of your suspension/steering/tires.
  • (8) pins come in a set - (8) pins to one vehicle.

 

Ultimate Alignment Pins were designed by Austin Lindsay, a diesel technician out of Sonoma County, California.  Working on light duty diesel pickups, Austin noticed factory alignment pins would be falling out or bent within a couple years.  Why would you trust your alignment and your tires to an alignment pin with such a poor design.  After working with multiple concepts, the Ultimate Alignment Pin was born!

 

His business partner, Bill Wallace has helped bring Ultimate Alignment Pins from an idea to production.  Bill loved the Ultimate Alignment Pin from the start and knew Austin had invented a new industry standard. 

 

Save Your Tires

Imagine you buy a new truck and in 1-2 years your tires are wearing unevenly and worst of all your truck is drifting to the right while driving down the road.  No one should have to deal with this on a new or old vehicle.

Ultimate Alignment Pins will keep you alignment straight for years, they will not fall out and they will not bend. 

Ultimate Alignment Pins will last for at least ten years, almost 10x the factory pin lifespan.

Millions of GM Vehicles

Over one million GM trucks and SUV’s are sold each year that could benefit from Ultimate Alignment Pins.  Nearly 30-40 millions GM vehicles with independent front suspension are still on the road today. 

Every single one of these vehicles could benefit from our alignment pins.  This pin will set the standard.

Ease of Alignment

If your alignment pins are bent or falling out, it is impossible to perform an accurate alignment.  Technicians are forced to either replace the pins or compensate camber/caster.

Ultimate Alignment Pins will firmly stay in place so technicians can perform alignments quicker and more accurately.

TSO Leveling Kit

"You can have any color you want, so long as it's black."

That worked for Henry Ford in 1908.

But it doesn't work in 2025.

The industry standard? Basic black.

Want something different? You know the drill: Buy the kit. Wait for delivery. Find a powder coater. Wait another 2 weeks. Hope they get it right.

The TSO 3" Custom Leveling Kit is the first bolt-on leveling system built your way—12 premium colors, full custom options, two-tone capability—shipped direct from our Blountville, TN facility.

No waiting. No cutting. No settling.

Just a custom suspension setup that turns heads and breaks necks before you even drop the tailgate.

3" WITHOUT THE HACK JOB.

Them: Want 3" of lift? Great. Grab the angle grinder and cut your frame up. Hope you measured right.
Us: Engineered clearance directly into the control arm. True bolt-on installation. No cutting. No fab work. No regrets.

3-hour DIY install. Zero permanent modifications.

The interactive truck builder shows you exactly what your setup will look like—in real time—before you order.

Pick your base color. Choose your overlay. Add FOX shocks. Watch your truck come to life.

No guessing. No hoping. Just your custom build, rendered on your screen.
