TRQ Front and Rear Brake Pad & Rotor Kit for 2003-2009 GX470

In this review the TRQ Front and Rear Brake Pad & Rotor Kit is evaluated for owners of 2003-2009 Lexus GX470 and Toyota 4Runner who need a complete replacement solution. The bottom line: the kit is a practical, cost-effective option for a full brake refresh because it bundles front and rear semi-metallic pads with matching vented rotors sized to the factory diameters, and the parts are built as direct-fit replacements to simplify installation for DIYers and independent shops.

Key Features

• Complete kit: Includes front and rear semi-metallic brake pad sets plus two front and two rear vented rotors so you get a full axle-to-axle replacement in one purchase.
• Direct fit components: Rotors and pads are pre-assembled to match original fitment, which reduces the need for machining or modifications during installation.
• Semi-metallic pads: The pad friction material balances stopping power and durability, giving confidence for daily driving and towing conditions common to GX470 and 4Runner owners.
• Factory-size rotors: Front rotors measure 13.31 in (338mm) and rear rotors measure 12.28 in (312mm), matching the vehicle factory diameters for consistent braking feel.
• Vented rotor design: Both front and rear rotors are vented to help dissipate heat and reduce fade under repeated braking.

Who It's For

This kit is aimed at hands-on owners and independent mechanics who want a single-package replacement that covers both axles for 2003-2009 Lexus GX470 and Toyota 4Runner models with the specified rotor sizes. It is particularly useful for drivers who tow or carry heavier loads and want durable semi-metallic pads with OEM-sized rotors.

Drivers looking for low-dust ceramic pads, high-performance track compounds, or vehicle fitments outside the listed years and rotor diameters should look elsewhere. Also, anyone needing a part-specific installation video should verify availability, as video resources are being expanded.

Pros & Cons

Pros

• Good value: buying pads and rotors together simplifies purchasing and often costs less than separate items.
