      I got a 2.5 rough country lift and I'm running 33s do I need this?

      • It would depend on your transfer case & rear driveshaft angles after installing your lift, but usually an SYE is not needed until you go over 3" of lift.

      What slip yoke eliminator would you recommend for my 06' TJ with a rough country 3.25" lift?

      • The Adams Driveshaft Heavy Duty Rear 1310 CV Greaseable Driveshaft would be a great addition to the Rough Country NP231 Slip Yoke Eliminator Kit and can be found here:

          Slip Yoke Eliminator

          I'm not sure what part fixed my jeep, but it was an weekend jeep to a daily driver. Best money I spent so far on it.
