Prothane 11-45028 Front Lower Inner Control Arm Bushing Kit

The Prothane 11-45028 is a front lower inner control arm bushing kit engineered from high-performance polyurethane to replace worn factory rubber bushings. Degraded OEM rubber bushings allow control arm movement that directly compromises caster and camber settings, resulting in steering wander, uneven tire wear, and reduced handling precision. This Prothane kit eliminates that slop with a firmer, more dimensionally stable bushing material.

Key Features:

• High-Performance Polyurethane Construction — Firmer than OEM rubber for improved compliance resistance and more precise suspension geometry maintenance
• Stable Alignment Retention — Resists deflection under load to help maintain accurate front-end caster and camber settings
• Available in Red or Black — Choose the color that suits your build
• Polyurethane/Steel Construction — Durable bushing material paired with a cadmium-plated steel sleeve for long service life
• Made in the USA — Manufactured domestically by Prothane, a trusted name in performance urethane suspension components since 1991
• Lifetime Warranty — Backed by Prothane's lifetime guarantee
• Includes Super Grease — Kit includes Prothane's specially formulated grease for proper installation and noise-free operation

Prothane polyurethane bushings deliver a noticeable improvement in steering response and front-end feel compared to soft factory rubber. While a slight increase in NVH (noise, vibration, and harshness) is expected with any polyurethane upgrade, the gains in handling precision and bushing longevity make this a worthwhile performance improvement for street and track applications alike.
