CSE Offroad carries transfer case parts for your Jeep that don't just replace what you have but improve on it. If you've raised the suspension by two inches or more, the Slip Yoke Eliminator Kit eliminates the need to drop your transfer case in order to avoid drive train vibrations. CSE Offroad has the standard and Mega Short kits, as well as the drive shafts with CV joints that you'll need to use along with the Slip Yoke Eliminator Kit. If it's time to replace your transfer case chain, or if you're servicing your transfer case anyway and you want an upgrade for greater reliability, install one of these superior chains by Alloy USA for your Wrangler, Cherokee or older CJ. We also have speedometer gears for NP 231 transfer cases with various numbers of teeth so you can calibrate your speedometer to work with whatever modifications you've made to your Jeep's drive train.
