Dynatrac PR 60 package

Journeyman said:

Hey everyone I just put my deposit on the hardcore package from dynatrac yesterday and wanted to check with everyone here to make sure I'm having them built correctly for my jku on 37's.
I ordered 5.13 with arb's and of course 8 lug [emoji1377]
Also what are you guys running for backspacing on your wheels. I really like the chamber pro 2's which also seam to have a bit more back spacing (4.02) vs most of the other popular choices are 3.5
I'd like to avoid having the whole tire sticking out beyond the rear fenders.

Congrats! I'm waiting on my axles from the same package. I went with Chamber Pro II's as well. I was going to go with Slabs, but DWiggles talked me out of it when mentioning how WIDE I would be with full width axles and slabs. I think you made a good choice with the chambers...WE made good choices :thumb:

Awesome - I love my Chamber Pros. Did you go black or raw alum? Congrats on the PR60's too. I was literally days away from pulling the trigger on those along with wheels but decided to pump the brakes for a while. I'm a bent flange away from doing it though.

With 37's you'll be more than fine with the backspacing on chamber pros and the 5.13's are the perfect gear ratio for 37's on a JK with auto trans (assuming that's your set up).

Congrats! I would look at the chamber pros which have 4" of bs or the trail ready beadlocks which have around 5" of bs.

I'm on the fence between the 44/60 and 60/60, got the cash for either one so cost is not a factor. I have a 2 door and my only concern on the 60/60 is the rear driveshaft angle since my driveshaft will be short and a lot of my terrain is rock gardens and I'm not sure if the extra weigh will slow me down, probably over thinking this. Tire coverage is a concern here too, that is the maximum backspace needed for 37's with 3.5 lift and flat fenders? TrailReady has beadlocks with anywhere from 3.5" - 6.0", so There are a few options. Congrats to the guys who have already pulled the trigger, I guess I better do it soon.

Congrats to you! :thumb:
As others have said, Chamber Pro II's will get the job done well and they're what I'm running now :yup:



Unless you order it differently, the rear 60 will be a high pinion and that'll help keep the driveline from at least not being any worse. It'll also help keep the pinion yoke up higher away from the rocks. If how wide you are is a concern, the 60/60 setup will have you sitting wider than stock so you will want to be looking at wheels with MORE back spacing. Trail Ready is definitely a choice to consider and something around the 4.5" of back spacing should help keep things tucked under the flares better. If you're going to run coil overs, this can cause a rubbing issue though. You just need to figure out what's more important to you.

Thanks Eddie [emoji1360] so with the extra 3" of axle the chamber pros at 4" of back space I should be good and not have any issues with clearance on the evo bolt on coilovers correct? That will be the next upgrade to my money pit!
Essentially with the 4 3/4" back spaced wheels I have now with the 1 1/4" spacers gives me 3.5 of back spacing on an 8 1/2" wheel. With my calculations even with the chambers I'll still grow 3/4" out

With the bolt on coil overs, yes, you should clear them with this setup. If you ever go DTD, you will rub your bypass shocks a bit at a full flex and turn.

Right on. Thanks that's great info to know. I don't plan on running that setup. But then again I never thought I'd get the point where I was running 37's and had the need for 60's either [emoji15][emoji848]
