The **AWD 38231-JK500 (07-24 Nissan GT-R, Infiniti G37, Lexus GX 460, and QX50 Intermediate Shaft)** is a high-performance, direct-fit replacement part designed to restore optimal drivetrain efficiency and reliability in select all-wheel-drive (AWD) vehicles from the Nissan GT-R (R35) lineup, alongside its luxury counterparts the Infiniti G37, Lexus GX 460, and the Nissan QX50. Engineered to meet or exceed OEM specifications, this intermediate shaft (also known as the transfer shaft or AWD drive shaft) is crafted from premium-grade steel, ensuring durability under the demanding conditions of high-performance driving, aggressive acceleration, and off-road excursions. Its robust construction minimizes flex and vibration, reducing wear on the drivetrain components while maintaining precise power delivery to all four wheels.

Whether installed in a track-focused GT-R, a refined Infiniti G37, a rugged Lexus GX 460, or the versatile QX50, this shaft delivers seamless integration with the vehicle s AWD architecture, ensuring compatibility with factory-specified CV joints, yokes, and mounting hardware. Built to withstand the stresses of both daily driving and spirited performance applications, this intermediate shaft is a must-have component for owners looking to optimize their vehicle s drivetrain while maintaining factory-like reliability.
