Bigger tires, caster adjustments

[Jobofly]

yes, just do one at a time. and make sure both arms sit roughly equal in their respective perches. There's enough slack in the frame side mount perches that to can shove one side a bit further forward than the other and it won't track straight. I had to rachet strap my axle back to get mine right but its totally doable. easy way to check, there are massive washers on the frame side draw around them with a paint pen. then you have a reference to get it back too when putting the new arms in. tighten all bolts to 190 ft-lbs paint mark em and check em after a couple hundred miles. if they didn't move your golden. this should net you 6.2-6.8 degrees of caster depending on your ride height. mines 6.4 with a 3/4 spacer lift and mopar extended LCAs.

Doing the install on Saturday. Just want to make sure I understand. I can remove the first one and I will have to move the axle forward slightly? Should I be concerned about it going to far? Is that what the ratchet strap is for?

To prevent the axle from swinging too far away either directions. Lift or lower the axle to the point where you can wiggles out the bolts by hand. Have a guide bar or a fat screw driver ready just incase you needs to align the holes. Do one at a time.

Edit. Remove the bolt at the axle end first, then carefully remove the frame side bolt without bumping the axle.

Technically u shouldn’t run into any issues. It should bolt right in. The rachet strap is just in case it rolls too far forward and the arm isn’t long enough then. I’ll PM you my number. So you can call me tomorrow if needed. I will be busy filming a movie but will watch for your call. Best of luck

Key Points:
- Always tighten control arm bolts with wheels on the ground.

- It may be helpful to have a wife or a friend to help out by rocking the tire forwards or backwards to assist in aligning the control arm bolt holes to the mounts.

- Torque lower control arms bolts to 103 lb/ft PLUS 145 degrees.

- Go ahead and check your torques on everything else while you're at it.

The bushings in "most " of the adjustable arms are better than OE Clevite bushings . That translates to less axle movement from the road surface, braking and so on . Soft OE Clevite bushings allow some slight axle movement which means more steering correction when driving even thought you may not notice it. It may only be slight but it will and you will notice the difference when you go to good bushings like a Johnny Joint in the front lowers in particular . Same goes for track bars with Johnny Joints . I can also tighten the arms when mounting them without the vehicle being on the ground with weight on it . That gives you more leverage for torque wrench work . I can fine tune my caster/pinion angle plus the arms are usually made much stronger . I use Johnny Joints on lowers and Metalcloak on uppers. I also don't have to loosen the control arms and let them reset any time I do something that effects ride height . It all comes at a price as there are 4 pairs to buy when you are done and good arms add up . By not doing adjustable or front geo brackets first on my JT and daughter's JL, I ended up with 2 sets of MOPAR extended arms and stock arms for conversation pieces in the garage. Thats mainly because I'm not willing to ship them , if you want to pick them up then we can talk..

Did you notice any length difference in the two different part numbers. I installed the AEV lift on my mojave and then the extended LCAs. But when I put the old one next to the extended ones I could not see any difference even measuring hole to hole. If I did see a difference it was very small and believe me I was trying to see a difference to justify spending the money AND changing them out. Thanks, Tony

The OE arms are about 1/4" shorter than the ones for the MOPAR lift kit and the bushings were a little different on the extended arms. It does make a difference when driving with the added caster . The Rancho Geo drop brackets made a much bigger improvement than the longer arms but they are more money but worth it to me .. I feel the Rubicon and Mojave both should of left the factory with the longer arms to begin with

I put the Mopar 2 inch lift on with their arms. Caster is now 6 deg. Perfect . I adjusted my toe to as close to 0 as possible. Also the synergy TB and DL along with. they're TB brace and sector shaft brace. Run my 37 KOs at 32 PSI. Life is good.
