73-87 GM Fleetside P/U 3in. Body Lift Kit

The 73-87 GM Fleetside P/U 3in. Body Lift Kit by Performance Accessories is engineered for classic truck enthusiasts and off-road builders seeking increased ground clearance and a more aggressive stance. This kit addresses a fundamental limitation of vintage GM pickups: factory suspension geometry that restricts tire diameter and underbody ground clearance. Whether you're upgrading to larger tires, improving approach angles for trail work, or simply refreshing the visual profile of your Fleetside, a 3-inch body lift provides measurable functional gains without the complexity of a full suspension overhaul.

Body lift kits separate the vehicle's cab and bed from the frame, raising the sheet metal 3 inches while keeping the suspension geometry intact. This approach preserves steering response, brake performance, and drivability—critical for vehicles that see both street and light off-road use. The Performance Accessories PA523 kit includes all necessary spacers, brackets, and hardware to achieve this lift safely and reliably. The 3-inch specification is the sweet spot for 1973–1987 GM Fleetside trucks, offering substantial visual transformation and tire clearance gain without affecting frame angles or creating transmission/transfer case binding issues that can occur with excessive lifts.

Installation suits the DIY mechanic with basic hand tools and a lift or jack stands; the process typically requires 4–6 hours and involves disconnecting the cab from the frame, inserting spacer blocks, and reinstalling hardware. After installation, you'll clear 31-inch tires on stock wheels and gain critical clearance for skid plates, fuel tanks, and engine bay components. This kit is ideal for owners restoring or modifying 1973–1987 Chevrolet and GMC C-series Fleetside pickups and works seamlessly with other bolt-on upgrades like performance exhausts or engine swaps. Proper torque specs and reassembly ensure long-term durability and safety.
