Energy Suspension 4.2160R Rear Leaf Spring Bushing Set - Polyurethane

The Energy Suspension 4.2160R is a rear leaf spring bushing set engineered from Energy's proprietary Hyper-Flex performance polyurethane. Designed as a direct replacement for worn or degraded factory rubber bushings, this set cushions the leaf spring from its mounting points while maintaining precise alignment under demanding conditions — whether on the street, the track, or off-road. Polyurethane construction outlasts and outperforms conventional rubber, resisting compression set and deterioration over time for long-term reliability.

Key Features:

• Made from Energy Suspension Hyper-Flex performance polyurethane for superior durability
• Full floating, non-binding design for smooth and efficient suspension operation
• Maintains proper alignment and improves handling, cornering, and overall vehicle control
• Fits into the remaining stock leaf spring — no major modifications required
• OEM performance and performance-grade rated
• Hardware included (zinc and steel); no separate bracket required
• Rear position application

This leaf spring bushing set is a specific-fit solution for select 2009–2014 Ford vehicles, including F-150 SVT Raptor applications. WARNING: This product can expose you to chemicals known to the State of California to cause cancer and reproductive harm.
