Jeep Wrangler TJ Axle - Front, Left Hand, Inner - Yukon Gear & Axle - Chromoly 4340, 30 Spline, 16.6in - `97-`06 is a direct-fit left inner axle built for TJ owners upgrading strength and reliability. This 16.6" Yukon 4340 chromoly axle is designed for Dana 30 front differentials with 30 splines and fits `97–`06 Wranglers and other vehicles using the same Dana 30 30-spline inner dimensions.

Manufactured from 4340 chromoly and produced with cold roll-formed splines and advanced induction heat treating, this Yukon axle is intended for high-performance and heavy-duty applications where larger tires and increased torque demand more than stock components. Yukon rates these axles for increased strength compared to OE pieces, and the shaft is backed by Yukon’s limited lifetime warranty against manufacturing defects and breakage (warranty is non-transferable; first return is a "no questions asked" replacement, subsequent resolution may be replacement or refund per Yukon/Randy’s Ring & Pinion determination).

• 16.6" inner length, left-hand (driver side) fitment
