Fesler Project OBS Silverado – Development Truck

This in-house OBS Chevy Silverado crew cab is more than a showpiece—it’s the development mule behind our growing line of 1988–2000 OBS truck products. From Fesler door panels and a custom metal dash to our console, seats, headliner, A-pillars, cowl, and full custom suspension, this truck is where new Fesler ideas get abused, refined, and proven on real streets.

Built by Fesler: What’s Custom on This Truck

The 1988–2000 “Old Body Style” Chevy and GMC trucks have officially crossed from workhorse to cult classic. Clean lines, square shoulders, and 90s nostalgia make the OBS platform one of the hottest trucks to build right now—and this Silverado is Fesler’s flagship example.

Nearly everything that matters on this truck was built in-house at Fesler. When you look at this interior and exterior, you’re looking at real parts we design, build, and test—not off-the-shelf catalog pieces.

  • Fesler OBS door panels and custom kicks designed around modern audio.
  • Custom metal dash built by Fesler, smoothed and laid out for clean wiring.
  • Hand-built console that ties the dash, seats, and rear cabin together.
  • Custom seats matched to the panels and console for a cohesive cockpit.
  • Full custom headliner and A-pillars—no factory plastic left behind.
  • Custom cowl and exterior details for a cleaner front end.
  • Full custom suspension set up to sit right and still be driven hard.

If a future Fesler OBS part touches the interior, glass, or stance, it probably started here. This is the truck we use to make sure an idea looks right, fits right, and survives real miles.

Inside the Fesler OBS Interior

The interior of this OBS is where most of our development happens. The door panels, console, seats, headliner, A-pillars, and metal dash are all Fesler-built pieces that form the blueprint for our production OBS interior line.

At night, the interior comes alive. Accent lighting traces the lines of the door panels, console, and seats without feeling like a theme-park ride. Everything you see—panels, dash, console, headliner, and A-pillars—was designed to look factory-level clean, just with a much higher standard than GM had in the 90s.

Daytime view of the cabin shows the full Fesler treatment—door panels, console, custom seats, headliner, and A-pillars all designed to work together. No mismatched plastics, no “this is close enough” fits. This truck is our proof-of-concept for a complete OBS interior system.

The Dakota Digital cluster sits inside a custom metal dash built by Fesler. The layout is simplified, modern, and easy to read, with wiring routed the way we’d want it on any high-end build—serviceable, hidden, and not fighting the design.

Parts Developed on This OBS

Fesler Project OBS Silverado FAQ

What platform is this truck?
This build is based on a 1988–2000 GM OBS (GMT400) Chevy Silverado crew cab platform. When we say “OBS,” we’re talking about the square-shouldered generation that runs from the late 80s through 2000 for certain models.
Which parts on this truck are Fesler-built?
The door panels, kick panels, console, custom metal dash, headliner, A-pillars, seats, cowl, and full custom suspension setup are all Fesler pieces or development versions of parts we are bringing to market. This truck is essentially a rolling demo of our OBS interior and exterior program.
Can I buy the exact parts used on this truck?
Many of the parts developed on this build already live in our OBS truck collection or are in the final stages of testing. Flush glass, interior panels, smooth cowl panels, carpet kits, and selected seating options are either active or coming online. If you see something specific on the truck, reach out and we can confirm availability or lead time.
Will this truck be at Barrett-Jackson or Dino’s Git Down?
That’s the plan. This OBS is being built with major events in mind, including Barrett-Jackson 2026 and high-profile truck gatherings like Dino’s Git Down and other Arizona shows. Follow Fesler on social media for the most current event schedule and sightings.
Can Fesler build my OBS or just sell me parts?
Both. We design and sell OBS parts to builders and DIY owners across the country, but we also take on a limited number of full builds each year. If you’re serious about having Fesler build or complete your truck, contact us with photos, your goals, and a rough timeline so we can discuss availability.
Do your OBS parts fit all cab styles and years?
Most Fesler OBS parts are engineered for specific body styles and years inside the 1988–2000 window. Always check the fitment notes on each product page, especially for standard cab vs extended cab vs crew cab, and for pickup vs SUV. If you are unsure, email us with the year, model, and a few photos and we can help confirm fitment.
