yes, but getting caster from modded arms puts the pinion too low. that's the issue. wrong fix for the wrong problem.
You still haven't clarified anything about the purpose of moving the axle an inch forward.5x6.5 said:Ok, I'm done with this one. I'm burnt out! Or maybe I'm just getting old.Thanks for the input guys.

Puts the axle back to where it should be with relation to wheel base and centers the tire in the wheel well..
And will effect drive shaft slope but not pinion angle..
Anybody running 5" RTE and RTE radius arms that would be willing to do a pinion angle measurement for me?!?!
you missed a bit of a discussion. 3" lift moves an axle about 0.1" back from stock location. I was asking him about moving an axle 1" forward.Jake1996D1 said:
Driveshaft slope is changed by about 0.2 of a degree by moving an axle 1" forward. Not a factor as well.

I wonder how accurate that is because RTE arms for a 3" lift are about 5/8 longer than stock..
Jake1996D1 said:
I talked to Bill two days ago he said they are 1 1/8" longer to put the axle back to stock location for the 5" lift and the 3" lift will also benefit from having the longer arm. They've been built like this from day 1 even before Bill owned RTE. If you dont belive me call and ask him.

Hmm weird I had a member here measure his and I measured a stock set and it was 5/8" None-the-less I need a set of arms for my 5" lift and I know for a fact they need to be at least an inch longer so my truck doesnt look stupid

I hear ya!!!
I had some arms that looked like RTEs but were knock offs some one made, JUNK!!! the welds were horrible. They were the same legnth as stock, so when I got my first set of RTE arms I compared them thats when I noticed they were longer. I doesnt really matter, they were built to accomplish a certain goal and they do the job and dont bend or fail!!!!
I believe you in that you typed what Bill told you. Doesn't make it an explanation for moving the axle forward an inch.5x6.5 said:
Clearly the front end geometry does not support it. However:
rear arms go to the bottom of the axle, not towards the centerline, so it may be more applicable to the rear - that is, RTE may have made the front arms longer to compensate for rear axle moving forward with 5" lift. It does make some sense because if one made rear trailing arms 1" longer without changing the upper A-arm, it would have pitched the rear pinion down considerably.
A-arm spacer is for tweaking the rear pinion angle, not explicitly for maintaining or changing the wheelbase. Are RTE rear arms also 1" longer?
I have "5in" RTE arms. They are 5/8 longer than stock. The do not put the wheelbase back to "normal". They actually move the axle further forward than stock. It is noticeable in the bend of the spring.
The rear a-arm extension can move the wheelbase back IF you use longer trailing arms with it and keep the pinion angle parallel with the out put of the case. This is nice if you want to run big shoes but not trim a lot on the back door. You can move the axle back a solid inch and do more trimming in the quarter panel instead of the door. It is more commonly used to move pinion angle up to use a DC shaft on big lifts.
RTE rear arms are not longer. They do come with spacers to make them longer. This is commonly used to put pinion back to normal on trucks that are lifted but not so tall that you "have" to use a DC shaft.
Longer arms in front will NOT affect pinion or castor angle. Only "cranking" them will affect pinion or castor. If you crank the arms to put pinion back to stock, it will throw your castor off a few degrees. This is where you use the drilled swivels.
I have 3in RTE springs in front with 5in arms now. My pinion angle is perfect with an HP Toy third up front.
I've owned both 3 and 5 inch RTE arms from every owner of the company. They were all the exact same as the ones I have now.

Arent you supposed to be on vacation?
Questions old mighty wise and experienced one - about how much pinion correction did you get from those arms?
Put the stock arms back on my truck tonight until I get some RTE arms. Pinion is about 5* too high now.. How much did the hi pinion change the pinion angle itself?
last but not least did use the rear holes or front holes on the A-arm extension? I have it on the front ones now but with the 5" coils I have to extend the links stupid long to get the pinion right. Thinking about switching it to the front holes.. thoughts?
I have RoverTracks rear arms and have plenty of room to space them if I want to push the axle back. If I space them any more though the pinion will be rotated down and I would need the A-arm extension.
