About this kit
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.
