SuperPro 1972 Mazda RX-3 Base Rear Leaf Spring Forward Spring Eye Bushing Kit

If you're looking to firm up the rear end of your 1972-1978 Mazda RX-3, especially if you notice wandering or instability under braking, replacing the old leaf spring bushings is a smart move. These SuperPro bushings are designed to replace the original rubber ones, which can degrade over time and lead to a mushy or unpredictable rear axle. By stabilizing the movement of the rear axle, these new bushings help prevent unwanted passive steer and keep your car tracking straight, even when carrying a load or towing.

SuperPro uses a durable polyurethane material for these bushings, which offers a more consistent performance than stock rubber. This material is known for its resilience and ability to maintain its shape under stress, which is key for keeping your rear axle planted. While the manufacturer's description mentions 4WD applications, the core benefit of stabilizing the leaf spring eye remains the same for any vehicle using this suspension setup. Upgrading these often-overlooked components can make a notable difference in how your RX-3 feels on the road, particularly during hard braking or when dealing with uneven surfaces.
