73 K20....crossmember time

So your choice cause its your truck but I have had more issues setting up motives than all the other brands I have done. When I say trouble it probably won't be a big deal to you. It's mostly the shim pack in the same axle is way different. Like I said no biggie for you.

If you could I might try to get usa standard. But I certainly understand the gotta go with the least expensive item there is

 

[blazinzuk]

Oh also in your application 5.38s done end of story

 

[wetoolowdingbangow]

Coin flip?

While barbecueing!

5.38 is kinda emticing. It's going to be at roughly 2900 on the freeway...sounds ok to me. It won't see much road time other than getting back to the trailer.

Good to know. I saw USA had them for $255. I'm sure I could find a little better price then that but it's do able.

 

[wetoolowdingbangow]

Found usa for 195!

Has anyone gone from 4.10 to 5.38 or some big jump up? Night and day difference?

 

[sreidmx]

Well considering that is a full ratio up you will notice it.. but the performance increase will be worth it.

I haven't, but I'm staying tuned for more updates!

When I regear I am gonna go to 5.13's. Eventually planning on running 40s so I think that would work well with the 700 and 241.

 

[K85 Octane]

3.73 to 4.88
but tire size went 31" to 38"
you running those 40s was too much for 4.10, its going to feel awesome. You had way to much gas pedal actual on Rubicon, more crawling will insue

Right on. I'm going for the "let the clutch out and crawl without feathering" feel.

I have a friend with 40s and 5.13. Similar trans and it's a real stump puller.

Very true. I felt like I was bucking too much because of the throttle I had to give it.

 

[kgblazerfive]

4:10 to 5:13 and went from 37's to 40's feels about the same.

Hmm sounds about right.

With the 465 208 and 5.38s would put me at roughly 92:1

 

[blazinzuk]

Get a hand throttle and everyone will think you have an auto.

I forgot you were 465. Definitely 5.38s. One guy I wheeled with alot wished he had gone 5.38 when he was 5.13. He just needed it a smidge lower and his clutch would have been happier.

He was on 40s

5.38s then. I dont know much about the hand throttles...ill have to look them up. Ill tell you one thing, im damn sure looking forward to engine braking.

 

[blazinzuk]

So in my life I have wheeled autos and manuals.

I can truly say I have never missed engine braking

 

[wetoolowdingbangow]

Hmm. We have some steep stuff going on here. Aftern seeing a few manual set ups im just amazed at the control down hill. Im sure there both great if tailored right. Autos freak me out. I have bad luck with them.

 

[GWeakland620]

I went from 308's to 456's on 36 iroks. That was a crazy difference.

 

[wetoolowdingbangow]

Nice! I think itll be a good jump for me.

I read the whole internet last night about 5.38s. Lots of problems in the beginning with those gears but it seems like all of those things have been worked out.

It look like both dana 60 and 14 bolts are getting the 5.38 ratio from 8/43. I havent seen any failures as of yet...
