A suspension modification designed for Chevrolet and GMC vans and SUVs manufactured between 1973 and 1987, this specific equipment raises the car’s physique by two inches. It sometimes contains parts similar to lifted springs, blocks, or torsion bar keys, and longer shocks to accommodate the elevated trip peak. These kits are particularly engineered to suit the chassis and suspension geometry of those basic autos.
Putting in such a modification affords a number of benefits, together with enhanced floor clearance, permitting for bigger tires and improved off-road functionality. It additionally contributes to a extra aggressive aesthetic. Traditionally, modifications like this had been common amongst truck fans looking for each improved efficiency and a definite look for his or her autos. The provision of those kits demonstrates continued curiosity in customizing and restoring these basic vans.
The next sections will delve into particular elements of choosing, putting in, and sustaining suspension carry methods for these vans, together with issues for trip high quality, dealing with, and potential modifications to associated parts.
1. Journey High quality
The choice to raise a ’73-’87 Chevy truck with a two-inch carry inevitably invitations a dialog about trip high quality. The factory-tuned suspension, rigorously engineered for a selected steadiness of consolation and functionality, faces alteration. Whereas the carry would possibly supply enhanced off-road potential or a extra imposing stance, the inherent traits of the trip are topic to alter. The unique springs, shocks, and suspension geometry are calibrated to work in concord; introducing carry blocks or modified springs disrupts this equilibrium. A stiffer trip would possibly end result, transmitting extra street imperfections on to the occupants. The delicate nuances of bump absorption, as soon as a trademark of those basic vans, could grow to be much less forgiving.
Contemplate the widespread state of affairs: A ’78 K10, initially a farm truck, undergoes a two-inch carry. The proprietor, looking for to accommodate bigger tires for improved traction in muddy fields, opts for a budget-friendly equipment. Nonetheless, the ensuing trip transforms from compliant to jarring, making even routine journeys to city uncomfortable. This illustrates a direct consequence: neglecting the interconnectedness of suspension parts can severely compromise the driving expertise. Matching the carry with applicable shocks, designed to enhance the altered spring fee, turns into paramount. Equally, consideration should be paid to the angles of management arms and the monitor bar to mitigate potential bump steer and preserve predictable dealing with.
Finally, preserving an affordable trip high quality with a two-inch carry on a ’73-’87 Chevy requires a holistic strategy. The choice of the carry equipment itself is simply the start line. Cautious consideration should be given to the selection of shocks, the situation of present suspension parts, and the willingness to spend money on vital supporting modifications. The purpose shouldn’t be merely to boost the truck, however to take action in a way that minimizes the sacrifice in consolation and management, making certain that the elevated stance enhances, relatively than detracts from, the general driving expertise.

The Preliminary Phantasm
At first look, the two-inch carry seems to be an easy answer. The extra house appears adequate to accommodate tires that might in any other case rub in opposition to the fenders or suspension parts. Nonetheless, the satan lies within the particulars. Tire sizes are hardly ever absolute; variations in manufacturing and tread patterns can considerably alter their precise dimensions. A tire marketed as a 33-inch could, in actuality, measure nearer to 32.5 and even 33.5 inches. This discrepancy, seemingly insignificant, will be the distinction between a profitable modification and a irritating encounter with persistent rubbing. A ’77 Blazer proprietor discovered this the arduous means, discovering that his chosen 33s scraped the inside fenders throughout full turns, regardless of the marketed two-inch carry. The preliminary phantasm of ample clearance can shortly shatter below the burden of actuality.
-
The Offset Issue
Past the tire’s diameter, the wheel’s offset performs an important function in figuring out clearance. Offset dictates how far the wheel and tire meeting extends outward from the hub. A wheel with a damaging offset will push the tire additional away from the suspension however nearer to the fender edge. Conversely, a optimistic offset will tuck the tire nearer to the suspension, probably creating rubbing points on the management arms or sway bar. Contemplate a ’85 C10 pickup fitted with aftermarket wheels boasting an aggressive damaging offset. Whereas the carry offered the mandatory vertical clearance, the tires now protruded past the fenders, requiring the addition of fender flares to keep up authorized compliance and forestall harm from street particles. The offset issue is a essential, but usually neglected, aspect within the tire clearance equation.
-
The Artwork of Compression
Static clearance, measured when the truck is stationary, is simply half the story. Throughout operation, the suspension undergoes compression because it encounters bumps and uneven terrain. This compression reduces the obtainable clearance, probably resulting in rubbing even with seemingly sufficient house below regular circumstances. Off-road fans are significantly conversant in this phenomenon. A truck would possibly seem completely succesful on a paved street, solely to expertise important tire rubbing throughout a weekend tour on a rocky path. The quantity of compression varies relying on the spring fee, shock absorber damping, and the general weight distribution of the car.
