Wheel Stud Kit - Lexus IS300 (5)

The Wheel Stud Kit - Lexus IS300 (5) by ARP is a critical fastening component engineered for drivers who demand reliability and performance from their suspension systems. Whether you're upgrading wheel fitment, replacing worn studs, or building a modified IS300, premium wheel studs are non-negotiable—they secure your wheels under acceleration, braking, and cornering loads that exceed factory specifications. This five-stud set is purpose-built for the Lexus IS300 platform, ensuring exact fitment and load capacity without modification or compromise.

ARP's Wheel Stud Kit features chromoly construction with cadmium plating, delivering superior tensile strength and corrosion resistance compared to OEM fasteners. Each stud measures 12mm x 1.50 thread pitch with a 2.600-inch length and 0.558-inch knurl diameter, engineered to work seamlessly with Lexus IS300 hubs and aftermarket wheels that share the same lug pattern. The chromoly material resists stress fatigue under repeated clamping cycles, while the knurled section prevents fastener rotation during installation—a critical detail mechanics appreciate when torquing to specification without slippage or galling.

IS300 owners upgrading to larger wheels, lowering springs, or aggressive driving benefit most from this stud set; OEM fasteners often become the weakest link once modifications increase lateral and vertical loads. Installation requires a press or specialized stud removal tool to extract the old fasteners, then press-fitting the new studs until the knurl seats fully against the hub. Torque to 76 ft-lbs using a calibrated wrench in a star pattern to ensure even clamping force. This kit of five studs replaces one complete wheel's fasteners, making it ideal for rotational replacement or full-vehicle upgrades on the IS300 platform.
