Review PROTHANE Rack And Pinion Bushing Kit 79-9/84 Used fits MUSTANG

The **Prothane 6-702-BL Mustang Rack Pinion Bushing Kit (for 1979 1/2 through 1984 models)** is a premium aftermarket solution designed to restore smooth, precise handling and eliminate the chronic noise, play, and premature wear that plague the stock rack-and-pinion steering systems found in first- and second-generation Ford Mustangs. Engineered specifically for the 1979 to 1984 models including the Fox-body platform this kit replaces the original rubber bushings with high-performance **Prothane polyurethane components**, which deliver superior durability, reduced friction, and enhanced steering responsiveness. The bushings are precision-machined to exacting tolerances, ensuring a perfect fit within the rack s mounting points while maintaining the original geometry of the steering linkage. Unlike conventional rubber bushings, which degrade over time under the constant stress of road imperfections, Prothane s reinforced polyurethane formulation resists oil, heat, and abrasion, making it ideal for both daily drivers and enthusiasts pushing their Mustangs through spirited driving conditions. Installation is straightforward, requiring only basic tools, and the kit includes all necessary components including the lower and upper rack bushings to complete a full restoration of the steering system s integrity. By upgrading to this kit, owners can bid farewell to the rattles and slop associated with aging rubber bushings while gaining a firmer, more engaging steering feel that enhances both comfort and control. Whether restoring a classic Mustang to its original glory or upgrading a project car for improved performance, the **Prothane 6-702-BL** is a reliable, long-lasting solution that ensures the steering system operates with the precision and reliability it was designed for.

The **Prothane 6-702-BL Mustang Rack Pinion Bushing Kit (for 79-9/84 models)** is a popular aftermarket solution for reducing noise, vibration, and wear in the steering rack of early Ford Mustangs. Below are the key pros and cons of purchasing this kit, followed by a conclusion and recommendation.

1. **Reduces Noise and Vibration** The Prothane bushings are designed to dampen road noise and steering vibrations, providing a quieter and smoother driving experience, especially on rough roads or uneven surfaces.

2. **Improves Steering Feel** These bushings can enhance steering precision by reducing play and flex in the rack, making the steering more responsive and accurate.

3. **Durability and Longevity** Prothane is a high-quality rubber compound that resists wear better than stock polyurethane or rubber bushings, extending the life of the steering components.

4. **Easy Installation** The kit is designed for straightforward installation, typically requiring only basic tools and minimal disassembly, making it accessible for DIY enthusiasts.

5. **Compatibility** Specifically engineered for the 79-9/84 Mustang rack pinion, ensuring a proper fit without modification.

6. **Cost-Effective Upgrade** Compared to full rack replacements or more complex steering upgrades, this kit offers a relatively affordable way to improve steering performance and comfort.

7. **Reduces Wear on Other Components** By minimizing excessive movement in the rack, these bushings can help prevent premature wear on the rack itself, tie rods, and other steering linkages.

1. **Limited to Specific Models** This kit is only designed for the 79-9/84 Mustang rack pinion. Owners of later models or different vehicle makes will need a different part number.

2. **Not a Permanent Fix for Major Issues** If the rack itself is worn or damaged, replacing just the bushings may not fully resolve steering problems. A full rack inspection is recommended before installation.

3. **Installation Requires Some Skill** While the kit is designed for ease of use, improper installation (e.g., incorrect alignment or overtightening) could lead to premature failure or steering issues.

4. **Potential for Dust and Debris Ingress** Like any steering component, the bushings can accumulate dirt and debris over time, which may require occasional cleaning or lubrication to maintain performance.

5. **Not a Performance Upgrade** This kit is primarily for noise reduction and comfort rather than enhancing handling or cornering performance. For serious performance tuning, additional modifications (e.g., poly bushings, rack spacers, or alignment adjustments) may be needed.

6. **Quality Variability** While Prothane is generally reliable, some users report inconsistent quality in aftermarket kits, so sourcing from a reputable seller is advised.

The **Prothane 6-702-BL Mustang Rack Pinion Bushing Kit** is a solid choice for early Mustang owners experiencing excessive steering noise, vibration, or wear. It offers a practical, cost-effective way to improve comfort and steering feel without requiring major modifications. However, it is not a universal fix it works best when the rack itself is in good condition, and it may not address deeper mechanical issues. For most drivers looking to quiet their steering and reduce flex, this kit delivers good value and performance.

If you own a **79-9/84 Mustang** and are experiencing **excessive steering noise, vibration, or a "spongy" feel**, this Prothane bushing kit is a worthwhile upgrade. Purchase it from a trusted supplier (such as RockAuto, Summit Racing, or a local Ford specialty shop) to ensure authenticity and quality. Before installation, inspect the rack and tie rods for wear if they are damaged, address those issues first. For DIYers, the installation is manageable with basic tools, but if you re unsure, consult a mechanic.

If your steering issues persist after installing these bushings, consider further diagnostics, such as checking for rack leaks, worn tie rods, or misalignment. For those seeking a more aggressive steering feel, you may later explore poly bushings or rack spacers, but the Prothane kit is an excellent starting point for comfort and reliability.
