I've looked on RockAuto and can't find any Moog UCA's available for 2008 Rangers 4x4's with torsion bar suspensions? I found the following available for 2007 models though.

K8708T Frt Susp; Upper; LH; 4WD; Problem Solver; Incl. bushings
K80068 Frt Susp; Upper; RH; 4WD; 1 piece design; Incl. bushings

Why wouldn't these work on a 2008 model? Is the K80068 is serviceable thought? Is there not a problem solver version available for the RH side? What about Lower BJ part #'s as well?

 

dont know about y it not for 2008, but yes it is servicable, i just got one yesterday, the K80068 is the problem solver, it said so right on the ball joint on mine. not sure about the lower ball joint #'s for yours though.

 

Anybody know if UCA's & BJ part #'s for a 2007 would be the same for a 2008 torsion bar suspension?

 

Yes they will work fine as all 98-11 control arms are interchangeable. You need K80771 lower ball joints.
