Dealer Description

1983 GMC Sierra Classic K20 3/4 Ton 4x4 -- Frame-Off-Rotisserie Restoration. Hands down, this is the cleanest and most meticulously detailed square body restoration we've ever seen. Well over 1,000 hours went into a full body-off restoration, where every nut, bolt, and seal was either replaced, refurbished, or rebuilt to the absolute highest standard---both cosmetically and mechanically. Clean accident free Carfax and Clean Washington Title. This rust free Idaho/Washington GMC truck was fully disassembled and stripped to bare metal, then refinished inside and out in a stunning Charcoal and Black two-tone base/clear coat by Tom's Auto Body. The result? Laser-straight panels, flawless gaps, and a fit and finish that exceeds factory specs. This Sierra Classic has the perfect stance, thanks to a 4-inch RCX suspension lift paired with 16-inch polished Raceline wheels wrapped in 35 inch BFGoodrich KM tires. Under the hood is a fresh ZZ-454 Big Block cranking out over 400 HP, backed by a dyno sheet. It's equipped with: MSD Distributor, Quick Fuel carburetor, Holley V-Drive pulley system, custom dual exhaust. The power is transferred through a smooth-shifting rebuilt Turbo 400 automatic transmission, connected to an NP207 transfer case that was refurbished, and new 3.73 gears---a drivetrain built for both power and reliability. Inside, no detail was overlooked: all-new interior, restored from top to bottom, vintage Air A/C system blowing ice cold, high-end custom audio system installed by Frank's Custom Upholstery, including amp and subwoofer. This truck isn't just a squarebody trophy---it's ready to drive, enjoy, and turn heads anywhere it goes. Come see it for yourself in our showroom or give us a call for more details.
