Product Description

The Energy Suspension 4.7101R Hyper-Flex Front C-Bushing Kit is designed to replace worn factory rubber radius arm bushings on classic Ford solid front axle trucks and SUVs. These bushings play a critical role in maintaining correct caster alignment, which directly affects steering stability and handling behavior.

By using high-performance polyurethane, this kit helps restore proper suspension geometry, especially on vehicles that have been lifted or experienced bushing wear over time. The 2° offset design corrects caster angle changes introduced by suspension lift or aging components, improving straight-line tracking and steering control.

Ideal for restored Broncos and classic Ford trucks, this kit delivers a durable, long-lasting upgrade over OEM rubber bushings while improving overall steering precision and road stability.
