If you’re looking to crank up the power on your LS3, LSA, or even an L92, the TSP LS3 Stage 3 Supercharged Camshaft is where it’s at. This isn’t just any camshaft; it’s designed for serious performance, especially if you’re running 15+ psi of boost. With specs like 231/239 duration, .640”/.629” lift, and a 115 LSA, this cam is aggressive and ready to unleash some serious horsepower from 3000 RPM and up.

Here’s the deal: if you’ve got a supercharged LS3 or LSA engine, this camshaft is going to give you some impressive gains. I’ve seen it add around 70 rear-wheel horsepower even on stock LS3 setups without a supercharger. That’s a solid bump, making it a smart choice if you’re thinking about adding a supercharger later on. Plus, it’s perfect for those max-effort builds where you really want to push the limits.

Now, if you’re running a manual transmission, you might experience a bit of bucking, but with the right tune, it can still be daily driven. Just make sure you’re equipped with a 2800 RPM or larger stall torque converter for the best results. And don’t forget about the VVT/AFM delete kit if it applies to your setup.

Features You’ll Appreciate:

  • Best for 6.0 and 6.2 engines with rectangular port heads.
  • Ideal compression ratio? Aim for 10.0:1 or higher.
  • You’ll need TSP/PAC Dual .660 Valve Springs for optimal performance.
  • Aftermarket stall converter? Yes, go for 2800 RPM or more.
  • No need to upgrade your rear gear.
  • Operating RPM range is between 2200 and 6800.
  • Expect a power increase of 70+ horsepower.
  • Drivability is solid with proper tuning, though manuals might feel a bit choppy at times.

Fitment:

  • Cadillac CTS-V (2009-2015)
  • Cadillac Escalade (2005-2014)
  • Chevrolet Camaro (2010-2015)
  • Chevrolet Corvette (2008-2013)
  • Chevrolet Silverado 1500 (1999-2013)
  • Chevrolet SS (2014-2017)
  • Chevrolet Suburban (2000-2014)
  • Chevrolet Tahoe (2000-2014)
  • Chevrolet Trailblazer (2006-2009)
  • GMC Sierra 1500 (1999-2013)
  • GMC Yukon (1999-2014)
  • Pontiac G8 (2008-2009)
  • Pontiac GTO (2005-2006)

Note: This camshaft comes in a 3-bolt design, so if your factory cam is a single-bolt, you’ll need a conversion kit to make it work. This kit includes the necessary upper timing gear and ARP camshaft bolts. We even offer an upgraded timing set for those looking to replace everything at once. Just a heads up, this camshaft is meant for competition use only and isn’t street legal.
