Whiteline W52299 Front Upper Control Arm Synthetic Elastomer Bushing Kit

The Whiteline W52299 is a front upper control arm synthetic elastomer bushing kit engineered to restore and enhance suspension performance. Worn upper control arm bushings directly compromise vehicle stability, steering precision, and braking efficiency — this kit replaces degraded factory rubber bushings with Whiteline's advanced synthetic elastomer compound for a like-new feel with improved durability.

Whiteline's proprietary synthetic elastomer formula is firmer and more resilient than OEM rubber, maintaining consistent suspension geometry under hard cornering, acceleration, and braking loads. Unlike rubber, the material resists deformation over time, helping preserve wheel alignment and reducing the unwanted flex that causes vague steering and unpredictable handling.

Kit Contents:

• 4 x synthetic elastomer shell bushings
• 4 x installation tubes
• Grease included

Key Features:

• Advanced synthetic elastomer construction — outperforms factory rubber in durability and geometry retention
• 43.5mm outer diameter (OD) — precision-engineered for correct fitment
• Superior elasticity and memory — resists permanent deformation under repeated suspension loads
• Eliminates clunks and vibrations — restores factory-fresh suspension feel and reduces NVH
• Improved steering response — crisper, more direct feedback for confident vehicle control
• Internal bore knurling and grease retention design — promotes lasting lubrication and smooth operation
• Lifetime warranty — backed by Whiteline's limited lifetime warranty

The W52299 kit is suitable for street and performance driving applications. Proper lubrication during installation is recommended — Whiteline EZE Grease or equivalent is advised to prevent noise and ensure long service life.
