SuperPro SPF5731K Control Arm Lower Inner Rear Bushing Kit Double Offset

The SuperPro SPF5731K is a Control Arm Lower Inner Rear Bushing Kit with Double Offset design, engineered to restore and enhance rear suspension geometry through the use of SuperPro's proprietary polyurethane construction. This kit is a direct upgrade over worn or degraded OEM rubber bushings, delivering measurably better handling response, alignment stability, and long-term durability.

Double Offset Performance Benefits:

• Positive caster correction: The double offset design introduces additional positive caster to both sides of the vehicle simultaneously, improving straight-line tracking and steering returnability
• Dynamic camber gain: Additional caster promotes increased camber as steering angle increases, maximizing tire contact patch in corners and improving grip
• Enhanced steering feel: Improved caster provides slightly weighted, more communicative steering feedback off-center, giving better feel for the handling limit
• Reduced tire wear: Corrected alignment geometry minimizes irregular and excessive tire wear caused by deflection in worn bushings

SuperPro Polyurethane Construction:

• Made from SuperPro's proprietary engineering-grade polyurethane formula — significantly more durable than OEM rubber
• Resistant to extreme temperatures, oils, water, and coolant
• Knurled bushing surface retains grease longer, reducing maintenance intervals
• Application-specific durometer (hardness) balances performance with ride comfort and NVH isolation
• Designed, engineered, and manufactured in Australia with 40+ years of suspension development expertise

What's Included:

• Polyurethane bushing set (lower inner rear position)
• Applicable hardware and washers
• SuperPro installation grease

SuperPro SPF bushings carry a lifetime warranty covering street, off-road, and motorsport use. This kit is the ideal solution for restoring rear suspension performance and correcting alignment geometry on applicable vehicles.
