The Adams Driveshaft Extreme Duty Series Front 1310 Slip-N-Stub Driveshaft with Solid U-Joints (part number ASDYJ-1310SF-S) is custom manufactured for the Jeep YJ Wrangler — front position. Compatible with tires up to 37 inches tall. For tires larger than 37 inches, Adams Driveshaft recommends upgrading to their Extreme Duty 1350 Solid Series. Each driveshaft is built to order using a center-to-center measurement taken at ride height.

Extreme Duty vs. Heavy Duty: This Extreme Duty Series uses solid non-greasable U-joints — the strongest U-joints Adams Driveshaft offers. The Heavy Duty Series (ASDYJ-1310SF-G) with greasable U-joints supports tires up to 35 inches. If running tires larger than 35 inches, the Extreme Duty Series is the correct choice.

Construction: Built from 2" × .120 wall DOM seamless tubing with a 7-inch long slip and stub. Solid non-greasable 1310 series U-joints sourced exclusively from Spicer and Neapco — two American manufacturers. Finished in gloss black show quality paint.
