Whiteline KCA433 Anti-Dive Caster Correction Control Arm Lower Inner Bushing Kit

The Whiteline KCA433 is a front control arm lower inner bushing kit engineered to deliver caster correction and improved anti-dive geometry. Replacing worn OEM rubber bushings with Whiteline's proprietary low-compliance synthetic elastomer bushings, this kit is designed to restore and enhance front suspension performance for both street and track applications.

The kit provides a 2-point caster adjustment, adding up to +1.0 degree of positive static caster to both front wheels while simultaneously altering front anti-dive and lift characteristics. Revised lower control arm geometry reduces front end dive under hard braking, while the high-performance elastomer bushings minimize dynamic caster loss to maintain sharp, consistent steering feedback throughout the full range of suspension travel.

Key Features:

• Provides 2-point caster adjustment with up to +1.0° positive static caster gain
• Revised anti-dive geometry minimizes front end deflection under braking
• Low-compliance synthetic elastomer bushings reduce dynamic caster loss
• Improved articulation, noise dampening, and vibration control over OEM rubber
• Promotes more consistent alignment angles during cornering
• Increases dynamic negative camber gain for improved cornering grip
• Delivers superior traction under both acceleration and braking
• Covered under Whiteline's 3-year warranty for performance alignment products

Kit Includes: 2 housings, 4 bushings, 4 tubes, 6 brackets, 6 bolts, 16 washers, assembly grease, and installation guide.

Whiteline's synthetic elastomer formulation is engineered to outperform standard OEM rubber in longevity and performance, providing the durability needed to maximize suspension efficiency over time. The KCA433 is a direct upgrade for enthusiasts seeking improved steering precision, more predictable braking behavior, and sharper corner entry response.
