Long Arm Upgrade Kit, fitment-checked
A long arm upgrade for the 4WD Jeep Grand Cherokee Laredo of 1999. Read the exclusion first: it does not fit AWD models, and a CV-style front driveshaft may bring on vibration that needs the driveshaft replaced.
The fitment here is narrow (the Jeep Grand Cherokee in Laredo trim, 4WD, for 1999) and the caveats matter as much as the fitment. AWD models are excluded outright. On vehicles running a CV-style front driveshaft, Rough Country warns that driveshaft vibration may appear after fitting, and clearing it means replacing the driveshaft. This is a substantial job: install time is listed at 8-9 hours and the kit arrives as four separate boxes. A downloadable installation guide is available. Shipping weight: 194 lb.
