Front Driver and Passenger CV Axle Set for Lexus GS300 GS350 IS Series

Our review of this CV axle shaft assembly set focuses on drivers who need a straight replacement for Lexus AWD front axles. The kit is a 2-piece, vehicle-specific, direct fit replacement designed to match original equipment reference numbers, so the biggest reason to buy is fitment confidence: it is tailored for several Lexus GS and IS model years and arrives as a complete front driver and passenger side assembly, saving time over sourcing individual parts. For owners wanting OE-style installation without modifying other components, this kit hits that mark.

Key Features

• Direct Fit: The assemblies arrive ready to install as front driver and passenger side units, reducing installation time and fitment guesswork.
• OE Replacement: Manufactured to replace original CV axles using known OE reference numbers for compatibility with multiple Lexus models.
• Complete Pair: The 2-piece kit includes both left and right front axles so both sides can be serviced at once for balanced performance.
• Vehicle Specific Fitment: The listing provides model year coverage to ensure owners of compatible GS and IS variants can confirm fit before purchasing.
• New Construction: These are 100% new assemblies produced to tighter tolerances intended to extend service life compared with worn originals.
• Aftermarket References: Uses common aftermarket reference numbers so replacement and warranty tracking is straightforward.

Who It's For

This kit is best for Lexus owners with All Wheel Drive GS300, GS350, IS250, IS300, IS350 or IS200t models across the covered years who need a direct, front-side axle replacement without the hassle of sourcing individual halves. Mechanics and DIY enthusiasts who prefer replacing both front axles together for consistent wear and handling will appreciate the complete pairing.

It is less suitable for owners who need custom-length or modified axles, or for applications outside the listed model years and AWD configurations. Buyers concerned about long-term boot durability may want to inspect materials or consider OEM parts if they need factory-specified rubber compounds.
