Best performance options for my 2017 5.3 RWD?

Hey folks! I’ve got a 2017 5.3 RWD with wides and a leveling kit. I’m looking to do some performance upgrades. Any recommendations on motors, transmissions, or rebuild kits? Not that I need it right now—my truck has 85k miles with no work done to it yet. Just exploring options!

You might want to consider a performance tune first. It can really wake up the engine without major modifications.

If you’re looking at motors, a crate engine might be a good option. They offer improved performance and reliability.

For the transmission, maybe consider a shift kit. It can improve your shifts without a full rebuild.
