The 1986 Chevrolet K5 Blazer remains a cornerstone of the American SUV legacy, but few examples offer the raw mechanical presence of this modified 4×4. Originally leaving the factory with a diesel powerplant, this truck has undergone a total transformation since 2020. The current owner invested heavily in both aesthetics and performance, resulting in a machine that feels significantly more capable than a stock unit. It stands as a testament to the enduring popularity of the square-body design when paired with modern engineering upgrades.
Custom Exterior and Versatile Top Options
The body wears a distinctive blue bedliner coating applied in 2023, providing a durable and texture-heavy finish that handles trail brush with ease. New chrome bumpers, a fresh grille, and updated weather stripping were installed during the refurbishment to sharpen the overall profile. For seasonal flexibility, the truck includes both a removable fiberglass hardtop and a convenient roll-up soft top. Fog lights and polished exhaust outlets add a touch of refinement to the otherwise rugged and utilitarian exterior styling.
Chassis Lift and All Terrain Equipment
This 1986 Chevrolet K5 Blazer sits on a 3-inch lift kit that provides the necessary clearance for its oversized Falken Wildpeak A/T tires. Polished 15-inch Pacer aluminum wheels offer a classic deep-dish look that perfectly fills the wheel wells. Beneath the surface, a Borgeson steering shaft and Energy Suspension polyurethane bushings improve the steering response and overall stability. Power-assisted front discs provide reliable stopping power, while the rear drums handle the remainder of the braking duties for this heavy-duty build.
Revised Interior and High End Audio
The cabin features refreshed brown vinyl upholstery on the front bucket seats and the folding rear bench for a clean, period-correct feel. To modernize the driving experience, a RetroSound Long Beach digital stereo was integrated into the dash. A custom center console now houses a powerful JL Audio subwoofer and amplifier for premium sound quality on the go. While the volume knob can be temperamental, the rest of the cabin remains highly functional with a cabin heater and clear auxiliary gauges.
Steering and Instrumentation Details
The driver interacts with a three-spoke steering wheel that frames a clear 85-mph speedometer and a suite of vital engine monitors. These auxiliary gauges provide real-time data on oil pressure, coolant temperature, and system voltage during operation. The five-digit odometer shows 93,000 miles, though the truck has only traveled 1,500 miles since the major mechanical overhaul. Black carpeting and a fresh dashboard pad contribute to a cabin environment that feels far more inviting than its original 1980s configuration.
Engine Performance and 408ci V8 Specs
The engine bay is dominated by a 402ci block bored to 408ci, featuring high-end components like Brodix Race Rite cylinder heads. To ensure consistent performance, the seller installed a Holley Sniper EFI system and a matching Hyperspark ignition setup. Internal upgrades include Speed Pro forged pistons and a Howard’s Cams hydraulic roller camshaft for significant power gains. A Champion aluminum radiator keeps the big-block cool, while long-tube headers feed into a custom stainless steel dual exhaust system. This V8 creates a visceral soundtrack while delivering far more torque than the original diesel engine.
Summary of a Square Body Transformation
This 1986 Chevrolet K5 Blazer represents a comprehensive approach to building a modern classic that can actually be driven and enjoyed. It features a robust TH400 three-speed automatic transmission and a dual-range transfer case for true off-road versatility. The inclusion of a recent driveshaft and transmission cooler shows a focus on long-term drivetrain reliability. With its clean North Carolina title and accident-free Carfax history, this K5 is ready for its next chapter. It offers a unique opportunity to own a fully sorted 4×4 with modern fuel injection and classic style.
