Spring-Thing Heavy-Duty Polyurethane Kit

Stop Rear Leaf Spring Clunks, Squeaks & Banging Noises

If your truck makes loud clunks, pops, squeaks, tapping, or banging from the rear leaf springs, Spring Thing Polyurethane Pads are designed to help eliminate the noise at its source.

Made from durable Red Polyurethane, these pads provide a firmer, longer-lasting alternative to our original neoprene pads while still cushioning contact between the leaf springs.

Polyurethane vs. Neoprene

Both versions are designed to reduce unwanted leaf spring noise, but the polyurethane version is made for customers who want a firmer and more wear-resistant material.

• Polyurethane: Firmer, more resistant to compression, and designed for maximum durability
• Neoprene: Softer and more flexible while still providing excellent noise reduction

If durability and long-term resistance to wear are your priority, the polyurethane version is the best choice.
