Prothane 11-46025 Rear Upper Control Arm Bushing Kit Jaguar MK1 MK2

The Prothane 11-46025 is a polyurethane rear upper control arm bushing kit designed as a direct replacement for the factory rubber bushings on Jaguar Mark 1 and Mark 2 vehicles (1960 and later). Prothane's polyurethane formula delivers significantly improved durability and chassis feedback compared to OEM rubber bushings, which degrade over time and introduce unwanted suspension flex.

Polyurethane construction resists oils, solvents, and road chemicals that cause premature deterioration in stock rubber bushings. The firmer material reduces suspension deflection under load, resulting in more precise handling and improved cornering response — a critical upgrade for both daily drivers and performance-oriented classic Jaguar restorations.

Key Features:

• Direct OEM replacement — installs in the factory location without modification
• Polyurethane construction for superior durability over factory rubber
• Improved chassis feedback and suspension precision
• Resistant to oils, solvents, and environmental degradation
• Fits rear upper C-arm (front and rear positions) on Jaguar MK1 and MK2
• Manufactured by Prothane — a trusted name in performance polyurethane suspension components

Prothane part number 11-46025 is a bolt-in upgrade that restores and improves the suspension geometry of your classic Jaguar, making it an ideal choice for restoration projects and performance builds alike.
