Upgrade your OBS Ford with our one-piece aluminum driveshaft! Fits 1993-1997 OBS Ford F250/F350 4x4 rear driveshaft (with 4-bolt flange at transfer case). Eliminate those pesky carrier bearing issues and get the ultimate strength upgrade at the same time. 
These shafts are built with the highest quality components available: NEAPCO 1350 series forged solid-cross u-joints, 5"x.125" 6061 T-6 Seamless aluminum driveline-specific tubing, forged aluminu weld yoke, and the SONNAX yokeshaft/sleeve unit. The SONNAX yokeshaft/sleeve unit is far superior in fitment and longevity to the Spicer version other shops use to offer a cheaper price.
 
The flange for the transfercase side of this shaft is a 2" Pilot Diameter and a 4.25" Bolt Circle (stock size) with threaded holes on the driveshaft flange. The stock rear pinion yoke on these trucks is 1350 series u-joint size. If you have swapped out for a later model differential, it is likely 1410 which is an option for this shaft when ordering. 
 
As always, these driveshafts are high-speed balanced and ship for FREE.
