I needed new lid lifters for my truck. I think it's called a ton or something. Went to the national dealership, 90.00 for these lifts. Went to a place that sells toppers and was told it would be difficult to find as I have a blank cover. Soooo, read the numbers on the side of an elevator, put them into the Revain and bam! Much smarter, perfect fit! This company even emailed a video when I needed help installing it. Would buy these lifts again, would buy from this company again.
