I installed these shocks as an OE replacement/upgrade on a 2006 Dodge Grand Caravan with 135,000 miles. Very easy to install. Great driving improvement. I also installed new strut assemblies at the same time for a complete ride upgrade. When installing, support the vehicle under the frame (not behind the rear axle). Attach the top of the shock absorber first. Use a jack under the axle to adjust the height to match the screw location on the underside of the shock absorber. After securing the van and removing the wheels, the installation took 10 minutes per side. Great fit and quality product.
