⚙️ Upgrade your Jeep’s backbone — no slip, all grip!
The Rough Country NP231 Slip Yoke Eliminator Kit transforms your Jeep’s NP231 transfer case by replacing the vulnerable slip yoke with a fixed yoke, dramatically improving off-road durability and driveline stability. Designed for 1997 and newer NP231 models on Jeep YJ, TJ, and XJ, this all-inclusive kit requires Rough Country’s Extended Travel Drive Shaft and prevents common failures like driveline vibration and rear output shaft breakage. Engineered for lifted Jeeps with larger tires, it’s backed by a Limited Lifetime Replacement Warranty, making it the ultimate upgrade for serious off-roaders.
