Delphi TD5603W Suspension Stabilizer Bar Bushing Kit - Rear

Overview

Delphi TD5603W is a rear suspension stabilizer bar bushing kit built as a standard replacement for select INFINITI applications. It uses rubber construction and OE-focused dimensional analysis to support proper fit and consistent bar isolation.

Key Features

• Rubber bushing construction for suspension bar support
• Standard replacement grade for service work
• Rear position application
• Black finish
• OE-oriented material and dimensional analysis

Detailed Description

Delphi TD5603W is engineered for rear stabilizer bar service where the original bushing has worn, hardened, or lost its shape. The rubber material and measured inside diameter, width, and height help maintain the intended interface between the bar and mounting point. Delphi applies OE expertise to its aftermarket steering and suspension portfolio, with testing that includes extreme temperature exposure and salt-spray durability evaluation. This part cross-references Honda/Acura-style replacement numbers 54613-1CA1A and K201563 for the same application. Fits 2014-2017 INFINITI QX70, rear; Fits 2013 INFINITI FX37, rear; Fits 2009-2013 INFINITI FX50, rear; Fits 2009-2012 INFINITI FX35, rear. Delphi TD5603W is a direct service part for INFINITI FX35, FX37, FX50, and QX70 rear stabilizer bar maintenance.

Common Uses

• Replacing cracked or compressed stabilizer bar bushings
• Restoring rear sway bar support and isolation
• Addressing clunking or looseness from worn bushing material
• Correcting fit issues caused by dimensional wear

Installation Notes

Install on the rear stabilizer bar location specified by the vehicle application. Verify the inside diameter, width, and height against the removed part before installation. Clean the mounting surfaces and inspect the bar for wear or corrosion that could affect bushing seating.

Quality Assurance

Delphi applies OE-focused engineering and testing to this part, including exposure to temperatures below -40 degrees C and above 120 degrees C, plus 720 hours of salt spray testing. The TD5603W is built using dimensional and material analysis to support OE-style compatibility.
