Installing such a modification offers several advantages, including enhanced ground clearance, allowing for larger tires and improved off-road capability. It also contributes to a more aggressive aesthetic. Historically, modifications like this were popular among truck enthusiasts seeking both improved performance and a distinct appearance for their vehicles. The availability of these kits demonstrates continued interest in customizing and restoring these classic trucks.
The subsequent sections will delve into specific aspects of selecting, installing, and maintaining suspension lift systems for these trucks, including considerations for ride quality, handling, and potential modifications to related components.
1. Ride Quality
The decision to elevate a ’73-’87 Chevy truck with a two-inch lift inevitably invites a conversation about ride quality. The factory-tuned suspension, carefully engineered for a specific balance of comfort and capability, faces alteration. While the lift might offer enhanced off-road potential or a more imposing stance, the inherent characteristics of the ride are subject to change. The original springs, shocks, and suspension geometry are calibrated to work in harmony; introducing lift blocks or modified springs disrupts this equilibrium. A stiffer ride might result, transmitting more road imperfections directly to the occupants. The subtle nuances of bump absorption, once a hallmark of these classic trucks, may become less forgiving.
Consider the common scenario: A ’78 K10, originally a farm truck, undergoes a two-inch lift. The owner, seeking to accommodate larger tires for improved traction in muddy fields, opts for a budget-friendly kit. However, the resulting ride transforms from compliant to jarring, making even routine trips to town uncomfortable. This illustrates a direct consequence: neglecting the interconnectedness of suspension components can severely compromise the driving experience. Matching the lift with appropriate shocks, designed to complement the altered spring rate, becomes paramount. Similarly, attention must be paid to the angles of control arms and the track bar to mitigate potential bump steer and maintain predictable handling.
Ultimately, preserving a reasonable ride quality with a two-inch lift on a ’73-’87 Chevy requires a holistic approach. The selection of the lift kit itself is only the starting point. Careful consideration must be given to the choice of shocks, the condition of existing suspension components, and the willingness to invest in necessary supporting modifications. The goal is not merely to raise the truck, but to do so in a manner that minimizes the sacrifice in comfort and control, ensuring that the elevated stance enhances, rather than detracts from, the overall driving experience.
2. Tire Clearance
For many owners of ’73-’87 Chevrolet and GMC trucks, the desire for larger tires is a siren song. The factory-equipped rubber, often deemed inadequate for the task at hand, pales in comparison to the aggressive stance and improved traction offered by a more substantial set. A two-inch suspension lift becomes the key to unlocking this potential, a gateway to a world of enhanced capability and visual appeal. Tire clearance, in this context, ceases to be a mere technical specification; it transforms into a symbol of aspiration, a tangible representation of the truck’s enhanced identity.

The Initial Illusion
At first glance, the two-inch lift appears to be a straightforward solution. The additional space seems sufficient to accommodate tires that would otherwise rub against the fenders or suspension components. However, the devil lies in the details. Tire sizes are rarely absolute; variations in manufacturing and tread patterns can significantly alter their actual dimensions. A tire advertised as a 33-inch may, in reality, measure closer to 32.5 or even 33.5 inches. This discrepancy, seemingly insignificant, can be the difference between a successful modification and a frustrating encounter with persistent rubbing. A ’77 Blazer owner learned this the hard way, discovering that his chosen 33s scraped the inner fenders during full turns, despite the advertised two-inch lift. The initial illusion of ample clearance can quickly shatter under the weight of reality.
-
The Offset Factor
Beyond the tire’s diameter, the wheel’s offset plays a crucial role in determining clearance. Offset dictates how far the wheel and tire assembly extends outward from the hub. A wheel with a negative offset will push the tire further away from the suspension but closer to the fender edge. Conversely, a positive offset will tuck the tire closer to the suspension, potentially creating rubbing issues on the control arms or sway bar. Consider a ’85 C10 pickup fitted with aftermarket wheels boasting an aggressive negative offset. While the lift provided the necessary vertical clearance, the tires now protruded beyond the fenders, requiring the addition of fender flares to maintain legal compliance and prevent damage from road debris. The offset factor is a critical, yet often overlooked, element in the tire clearance equation.
-
The Art of Compression
Static clearance, measured when the truck is stationary, is only half the story. During operation, the suspension undergoes compression as it encounters bumps and uneven terrain. This compression reduces the available clearance, potentially leading to rubbing even with seemingly adequate space under normal conditions. Off-road enthusiasts are particularly familiar with this phenomenon. A truck might appear perfectly capable on a paved road, only to experience significant tire rubbing during a weekend excursion on a rocky trail. The amount of compression varies depending on the spring rate, shock absorber damping, and the overall weight distribution of the vehicle. Addressing compression-related rubbing often necessitates trimming the fenders or further increasing the suspension lift, compromising the original goal of a modest two-inch elevation.
-
The Steering Stop Consideration
Another aspect affecting tire clearance is the steering stop. These mechanical limiters prevent the tires from rubbing against the frame or suspension components during extreme steering angles. When larger tires are installed, even with a lift, the steering stops may need adjustment to prevent rubbing at full lock. However, reducing the steering angle also diminishes the truck’s turning radius, potentially making it more difficult to maneuver in tight spaces. Finding the right balance between tire clearance and steering maneuverability requires careful consideration and, in some cases, aftermarket steering stop limiters to fine-tune the range of motion.
These interwoven facets underscore the complexity of achieving optimal tire clearance with a two-inch lift on a ’73-’87 Chevy truck. It is a process that extends beyond the simple act of installing a lift kit. A successful outcome hinges on a thorough understanding of tire dimensions, wheel offset, suspension dynamics, and steering limitations. The pursuit of larger tires, therefore, becomes a journey of careful planning, precise execution, and a willingness to adapt to the unforeseen challenges that invariably arise.
3. Installation Complexity

The owner, a seasoned mechanic with a well-equipped garage, approached the two-inch lift installation with confidence. However, the project soon revealed hidden intricacies. Decades of rust and corrosion had fused bolts, turning simple tasks into laborious battles. The original shocks, seized in place, required cutting torches to remove. The factory springs, weakened with age, proved difficult to compress and reinstall. What began as a Saturday afternoon endeavor stretched into a week-long struggle, punctuated by trips to the parts store and frustrated calls to fellow enthusiasts. This experience underscores a crucial point: the age of these trucks introduces a variable that transcends the inherent design complexity of the lift kit itself. The condition of existing hardware and components significantly impacts the ease, or difficulty, of the installation process.
Furthermore, the specific type of two-inch lift kit chosen contributes directly to the complexity. A simple block lift, while seemingly straightforward, can introduce driveline vibrations if not properly aligned and accompanied by necessary modifications, such as shims or a carrier bearing drop. A complete spring replacement kit, on the other hand, requires more extensive disassembly and reassembly of the suspension system. Regardless of the approach, proper torque specifications are essential to ensure safety and prevent premature wear. The installation instructions, often generic and lacking in detail, can leave even experienced mechanics scratching their heads. Ultimately, a realistic assessment of one’s mechanical skills, access to tools, and willingness to invest the necessary time is paramount before embarking on this seemingly simple modification.
