The 1999 Jeep Cherokee represents a pivotal moment in the evolution of the compact SUV, establishing a benchmark for capability and versatility that remains influential today. For owners looking to enhance the function and stance of their XJ, a 1999 Jeep Cherokee lift kit offers the most direct path to unlocking serious off-road potential. By increasing ground clearance and providing the necessary articulation, these kits transform the driving dynamics, allowing the suspension to compress and extend without binding or causing damage to vital components. This modification is not merely cosmetic; it is a fundamental upgrade that addresses the inherent limitations of the factory setup when confronted with challenging terrain.
Understanding the 1999 Jeep Cherokee Suspension
To effectively utilize a 1999 Jeep Cherokee lift kit, one must first understand the engineering of the original setup. The XJ utilized a sophisticated fully independent suspension system, featuring control arms, torsion bars, and a sway bar that worked in concert to deliver a remarkably car-like ride and superior handling for its class. While this design excelled on paved roads, it provided limited vertical travel for off-roading, making the bump stops prone to harsh bottoming out. Installing a lift kit involves replacing or augmenting these components to extend the suspension travel, which is the primary mechanism for achieving the desired increase in height and durability.
Types of Lift Kits Available
When shopping for a 1999 Jeep Cherokee lift kit, buyers are presented with distinct categories, each serving a specific purpose and budget. The primary choice exists between a suspension lift and a body lift; understanding the difference is critical for achieving the intended result. A suspension lift modifies the actual springs, shocks, and control arms to increase the distance the wheels can travel, directly impacting off-road performance and approach angles. Conversely, a body lift utilizes spacers to elevate the vehicle's body relative to the frame, offering a cheaper but less capable solution that primarily creates gaps for larger tires without improving clearance or articulation.
Budget vs. Performance Lift Kits
The market for 1999 Jeep Cherokee lift kits ranges significantly in price and complexity, generally falling into budget, mid-grade, and performance tiers. Budget kits often consist of basic block spacers and generic shocks, which may suffice for mild trail use but often compromise ride quality and long-term reliability. Mid-grade and performance kits, such as those from brands known for off-road durability, typically include coil spring or torsion bar extensions, upgraded shock absorbers with remote reservoirs, and reinforced control arms. These systems are engineered to maintain proper alignment and geometry, ensuring the vehicle remains safe and drivable both on the trail and the highway.
Tire Size Considerations
Lifting a 1999 Jeep Cherokee is almost universally tied to the goal of fitting larger tires, which is the most effective way to increase ground clearance and traction. The stock XJ was designed for relatively compact rubber, so a lift provides the necessary clearance for diameters often ranging from 31 to 37 inches, depending on the lift height and available fender space. However, simply mounting larger tires is not without consequence; it requires attention to gearing. Increasing tire diameter alters the effective gear ratio, which can strain the drivetrain and reduce fuel economy, necessitating a re-gearing of the differentials to maintain optimal engine performance and efficiency.
Installation and Alignment
While a DIY enthusiast with a robust toolset can tackle a 1999 Jeep Cherokee lift kit installation, the process is labor-intensive and requires careful attention to detail. The project involves unbolting the entire suspension assembly, pressing out old bushings, and welding in new components if necessary, followed by a meticulous reassembly. Crucially, a professional wheel alignment is non-negotiable after the installation. Because the lift alters the angles of the wheels relative to the road, a misalignment will result in rapid tire wear, the vehicle pulling to one side, and sloppy handling dynamics that compromise safety.
