GMC Yukon trim comparison
2024 GMC Yukon SLT vs Denali Ultimate
The Yukon SLT starts at $64,900 while the Denali Ultimate is $98,755. That $33,855 gap buys 8 meaningful differences.
This is a powertrain and drivetrain change. The Denali Ultimate gets the 6.2L V8 and 4WD, so the $33,855 is buying a different driving experience, not just nicer trim.
This is a real hardware fork, not just a trim-label shuffle. The SLT is enough if the 5.3L V8 with RWD already fits your routine; the Denali Ultimate only earns the jump when the 6.2L V8 and 4WD setup is the point of the upgrade.
The cleanest way to feel this upgrade is through the payment: about $596/month more over 60 months, or roughly $35,760 extra all-in once interest is included. If that different powertrain is not part of your real use case, the cheaper trim keeps more money in your pocket without changing the core experience you need.
Lock one trim, change the other side, and move through exact pair pages without resetting back to the full lineup every time.
