Details

This one-ton custom 1989 GMC Sierra 3500 crew-cab pickup received a frame-off rebuild that was converted from a long bed to a short bed, because GM never offered a short-bed crew cab in this model. It is powered by an iron-block 6.0-liter LS engine with Brian Tooley Stage 1 cam, with the factory GM computer to control it, and breathing through headers and a custom dual exhaust. The cooling for the engine is supplied by an aluminum Entropy radiator with dual electric fans. It also features an on-board air compressor, air tank, air horns and a new Odyssey battery. Power is backed by a built 4L80E automatic transmission with an NP205 transfer case and is cooled by a heavy-duty Derale transmission cooler with an electric fan. It is equipped with a steel front driveshaft and a 5-inch rear aluminum driveshaft, along with a Dana 60 front axle and a GM 14-bolt rear axle - both one ton - with 5.13 gears in both the front and rear axles. Stopping power is provided by 4-wheel disc brakes with hydro-boost. The steering is hydraulic-assist from PSC. The suspension sits on a custom Offroad Designs 4-link with coilovers at all four corners, and approximately 10 inches of lift. It is also equipped with Reid Racing steering knuckles, as well as Offroad Designs raised HD crossover steering with front and rear custom splined sway bars. The rear axle features a heavy-duty axle truss. The front and rear 4-link bars are super heavy-duty bars and Heim joints. This truck also features King 2.5-inch coilover shocks with bypass and removable King nitrogen-filled bump stops at all four corners. All suspension is custom-fabricated and installed by a professional off-road shop. The frame and chassis are painted black with new nuts and bolts and all-new fuel and brake lines. It rides on custom 20x10-inch aluminum Rally-style wheels wrapped in four brand-new Michelin MPT, measuring approximately 41 inches tall, along with new Warn lockout front hubs. The exterior was repainted in factory Bright Blue, while the bumpers, grilles, exterior mirrors and side-tube step bars are painted gray to match the wheels and interior. The exterior features a billet front grille, custom-designed and machined badging and GSI billet door handles. All exterior lighting was converted to LED and features all-new window and door seals, as well as tinted windows with lifetime window film. The inside of the bed has a spray-in bed liner with a BedRug kit on the bed floor, a tailgate converted to bear claw latches and a paint-matched SnugTop bed cover over the top. The interior features front and rear late-model bench seats wrapped in gray leather with consoles and cup holders, along with brand-new carpet, suede headliner with Suburban overhead console and a brand-new GM dash pad dyed to match. It is also equipped with Dakota Digital gauges, a RetroSound stereo head unit with Bluetooth and all-new speakers. Billet interior accessories include steering wheels, shifter arm and pedals. All interior lighting was converted to LED. It is also equipped with all-new windows and lock switches. **TITLED AS 1989 GMC R35 CONVENTIONAL**
