Time to upgrade the stock drive shafts, jkur, 3.5” lift, 35’s, stock front axle shafts,, nitro rears . Any reason not to skip 1310’s and go to 1350’s? (Hope to up grade to tons eventually)
1350's are just more money. I agree with running flanges on both ends as well. If you do Tons later you just have to have them re-tubed and shortened. Way cheaper than buying new drive shafts. Only other drawback is that you are likely moving your weak link in your drivetrain to the R&P or shafts. Check your drive line angles too as 4 doors can generally get away with not doing a double Cardon shaft that will save you money and time on the maintenance. Make sure to get solid u-joints.
