SuperPro 1972 Mazda RX-3 Base Rear Shackle Bushing Kit

These bushings are often overlooked when upgrading the suspension of a 4WD. Leaf spring bushings stabilize the movement of the rear axle, inferior bushes in this area will cause the solid rear axle to move and impart rear end passive steer to the vehicle. It also causes the vehicle to 'wander' all over the road and be unstable under heavy braking. This can be especially noticeable carrying a load or towing a boat or caravan. The OE rubber style bushes are designed to work at standard height with standard tires and with standard loads. By fitting SuperPro Bushings and upgrading to Greaseable Shackles the rear end of your 4WD will handle just about anything you can throw at it!

Upgrade the rear suspension of your classic 1972-1978 Mazda RX-3 with the SuperPro SPF0040K Rear Shackle Bushing Kit. Leaf spring bushings play a critical role in stabilizing rear axle movement, and worn or inferior bushings can contribute to passive rear-end steering, road wandering, and instability during heavy braking. These symptoms can become more noticeable when carrying additional weight or towing.

They help maintain more consistent leaf spring and rear axle movement, supporting predictable handling and improved stability on the street.
