Dana 44 / 10 Bolt Flat Top Knuckle, 4 Hole, Passenger Side, Bottom Up Taper With Ball Joints and Studs Installed

WFO 159BU-4-BJ
Pricing: $395.00


Introducing WFO's factory replacement passenger side flat-top knuckle. CNC milled, drilled, and tapped to 9/16” x 18 threads. The tie rod tapered hole on this knuckle is tapered from the bottom up. Also, we have installed the ball joints and studs already to make it easier for you.

Our knuckle boasts a thicker and stronger casting compared to the factory knuckles, ensuring enhanced durability. Additionally, it features an added 4th hole to accommodate aftermarket steering arms.

This knuckle is perfect for high-steer conversions! However, if you plan on utilizing cross-over steering and connecting your factory tie-rod, please consider the following details before selecting the appropriate version:

  • All Chevy Dana 44 axles from 1971 to 1976 had "top down" taper. 
  • On all Jeep Wagoneer front axles, the taper was also "top-down."
  • All Chevy Dana 44 axles from 1977 to 1991 were tapered from the “bottom up” and did not have a flat-top knuckle on the passenger side. If you are putting this on a 1977-1991 front axle, please select one with "bottom up" taper.


PLEASE NOTE: This knuckle has 6 spindle studs and will not fit Dodge, Ford, or Scout 44 front axles. Be sure that the axle you are installing this knuckle on uses 6 bolt spindles!
