Energy Suspension 4.2159R Rear Leaf Spring Bushing Set - Red Polyurethane

The Energy Suspension 4.2159R is a rear leaf spring bushing set crafted from Energy Suspension's proprietary Hyper-Flex performance polyurethane. Leaf spring bushings cushion the spring from the mounting bolt, absorbing road shock and maintaining proper spring alignment — and polyurethane outperforms conventional rubber by resisting compression set, chemicals, and wear over the long term. This set is a specific-fit replacement designed to restore and improve rear suspension performance.

Key Features:

• Made from Hyper-Flex performance polyurethane for superior durability over rubber
• Full floating, non-binding design for smoother, more efficient suspension operation
• Maintains proper alignment under demanding street, track, or off-road conditions
• Improves vehicle handling, cornering, and overall control
• Color: Red
• Hardware included (zinc/steel); brackets not included
• California Proposition 65: Cancer and Reproductive Harm warning applies

Engineered as an OEM-performance and direct replacement upgrade, this bushing set fits select 2015–2019 Ford Transit Van applications. Installation into the existing stock spring perch is straightforward, as the bushings are designed to fit the remaining stock hardware.
