hey guys i just orderd a rock krawler 3.5 flex lift, and a few more goodies. its goin on a 2012 2 door, should i run 35s or 37s and is there anything i need to know before i do the install on everything, im runnin 35s now with no lift and i got a set a 5100s comin to. with some jks goodies. thanks matt

 

Since you already have 35s I say run that for a while and see how you like it. Unless you have the budget to get 37s. You might have to look into either getting a D44 or look into re enforcing your D30 axles by gusseting it, getting chromoly shafts and possibly sleeving it. Regearing may be needed, but I see you have a 6 speed, it might be bearable with 3.73 gearing don't know if your 6th gear will be usable....

 

u would still need to re enforce a D44 as well. the only difference is a larger ring and pinion. the shafts, tubes, everything else is the SAME. they require the gussets and sleeves as well.

 

im goin to ordered the river raider axcle gueest kit when i order the 4.88 gears in a week or 2. i done replaced the front drive line cause i broke the factory one so all i have left is the rear and the axles, ima pull all my smittybilt stuff off and switch it all to river raider, bumper, rock sliders, rear bumper, fender, and rear quarter armor.
