Just replaced the front strut assemblies on the van and have noticed the back end is noticeable lower now. We tow a 6x10 trailer and often have a fair amount of weight in the rear of the van when towing. Had Airlift 100 bags installed until Airbag popped recently. I bought replacement kit but haven't installed because it is too cold outside to get old airbags out of springs. Airlift helped reduce scraping but still experienced it once in a while. Was thinking about other options to raise rear end so trailer doesn't scrape leaving driveway or highway when hitting a dip in the road. Saw other posts about installing Journey off road kit. Can you install just on the rear? Will that cause front end to dip too low and scrape curbs more than it does now? Any other options available? Van has 241,000 miles and still runs great otherwise.
