KAX Disc Brake Caliper Assembly Fit for Toyota 4Runner & Lexus GX470

In this review of the KAX disc brake caliper assembly, the bottom line is simple: this set is for owners who need a direct OE-style replacement for the front left and right calipers on Toyota 4Runner and Lexus GX470 models from 2003 to 2009. The reviewer found the assemblies to be well matched to factory dimensions, pressure tested, and treated with an antirust coating that should extend service life. Installation is straightforward for a DIY mechanic or a professional shop, and the included hardware and phenolic pistons make it a complete swap that restores reliable braking performance.

Key Features

• Vehicle Fitment: Directly fits Toyota 4Runner 2003-2009 and Lexus GX470 2003-2009 front left and right positions, reducing fitment guesswork.
• Complete Assembly: Ships as a 2pc set including brake caliper, phenolic piston, and installation hardware so the parts needed for a direct replacement are on hand.
• OE Reference Compatibility: Matches common reference numbers such as 47730-60261 and 47750-60261, helping ensure correct part matching for OEM-style repair.
• Durability: Calipers are coated with an antirust coating that helps protect the assembly from corrosion and can prolong service life in wet or salty conditions.
• Quality Control: Each caliper is inspected and 100% pressure tested, which helps restore proper braking function and gives confidence in reliability.
• Brake Performance: Four-piston design with a 1.754in piston diameter provides solid clamping force appropriate for the specified vehicle platforms.

Who It's For

The KAX caliper assembly is best for Toyota 4Runner and Lexus GX470 owners from model years 2003 through 2009 who need a direct OE-style front caliper replacement and prefer a complete kit that includes hardware. It suits DIY mechanics comfortable with brake work as well as independent shops that want parts that match OEM references.

Those who should look elsewhere include owners of different model years or other vehicle makes, and anyone requiring calipers preloaded with brake pads; these calipers are sold without pads and focus on matching OEM fit and function rather than offering upgraded performance braking components.
