Whiteline W73879 Leaf Spring Bushing Kit

The Whiteline W73879 is a direct-replacement leaf spring bushing kit engineered to restore and improve the suspension performance of leaf-sprung vehicles. A critical service item for any leaf-sprung vehicle, high mileage and heavy load carrying causes excessive wear on factory rubber bushings.

Key Features:

• Durable Synthetic Elastomer Construction: Whiteline's signature black bushings offer outstanding abrasion resistance, high load-bearing capability for 4WDs, trucks, and towing applications, flexibility, increased tensile strength, and chemical resistance to oil, grease, ozone, and weathering.
• Upgrade Over OEM Rubber: OE leaf spring systems use soft rubber bushings to mount the spring to the frame. While this rubber helps dampen vibrations, it doesn't last — OE rubber is prone to cracking and rotting due to contamination and wear, eventually failing completely, which severely reduces leaf spring performance and results in a rough ride and loss of control.
• Improved Handling and Longevity: The leaf spring is designed to spread the force of an impact over a wide area rather than focusing it to a single point — making dependable spring bushings critical to your vehicle's ability to haul heavy loads and drive smoothly over rough surfaces.
• Lifetime Warranty: Whiteline bushing kits with part numbers in the W-series are covered for their lifetime.

Whiteline offers advanced solutions to suspension and handling problems, with products designed to maximize your vehicle's potential whether it's a daily driver, street performance, or motorsport vehicle. The W73879 is a straightforward, high-value upgrade that extends service life and maintains proper suspension geometry for years of reliable use.
