The Works: Custom Sierra 2500 HD Denali Ultimate

2025 GMC Sierra 2500 HD Denali Ultimate

Dave Sinclair Customs delivered The Works to this GMC Sierra 2500 HD Denali Ultimate. It received a full chrome delete, a 3.5-inch lift kit, and a few extra touches that make it one of our most popular builds here at Dave Sinclair Customs in St. Louis.

Chrome Delete: All in the Details

Our in-house paint team handled nearly all of the chrome pieces on this Denali Ultimate. That includes:

  • The 2500 HD badges on the fenders

  • Door handles with the keyless entry buttons

  • Both front and rear emblems, color-matched for a clean, bold look

For areas that can’t be painted — like the side window trim and running boards — we partner with a local St. Louis vendor who vinyl wraps them. The same team also tinted the front windows to match the rears, completing the factory-plus aesthetic.

The two-tone chrome delete design combines black with the truck’s White Frost Tricoat color, which gives it that premium “custom from the factory” finish. On the rear emblem, the outline is black while the inside color matches the paint — White Frost. Up front, we went with a black GMC illuminated emblem that automatically lights up with the headlights at night.



Lifted, Balanced, and Built Right

This build rides on a 3.5-inch ReadyLift suspension kit and sits on factory 22-inch Denali Ultimate wheels that we powder-coated black. The only factory pieces swapped were the center caps and lug nuts, upgraded to custom versions for a finished look.

For tires, we chose Nitto Trail Grapplers — 34.5 inches tall and 12 inches wide — offering an aggressive stance while maintaining a smooth, quiet ride. The setup uses a +20 offset, which is our standard fitment for lifted trucks.

Accessories That Complete the Look

Every detail on this Denali Ultimate was built with purpose:

  • Remote-controlled retractable bed cover with an LED light underneath

  • GMC all-weather floor liners in both rows

  • All parts and accessories available through GMC Accessories

This build proves you can have power, style, and utility all in one.
