SuperPro Greasable Leaf Spring Kit

SuperPro is known for making well-built suspension components, and this greasable leaf spring kit is a prime example of their focus on improving vehicle handling. If you're driving a 1998-2004 Nissan Frontier and you've noticed your rear end feels a bit loose, especially when carrying a load or towing, worn leaf spring bushings could be the culprit. These aren't just any bushings; they're critical for keeping your rear axle stable and preventing unwanted steering inputs from the rear, often called passive steer, which can make your truck wander all over the road.

This kit replaces those worn-out original shackles and pins, which often corrode and damage the bushings over time. By fitting this complete package, you're getting greasable shackles, new fixed pins, and all the necessary bushings. The greasable design means you can easily add grease to keep everything moving smoothly and prevent premature wear, ensuring your rear suspension stays solid and predictable even under demanding conditions. This makes a notable difference in how stable your Frontier feels, particularly when you need it most.
