This is the top-of-the-line bumpstop spring tester from Longacre. This is the air cylinder operated model. This has the digital 4000 pound load cell. It has a digital travel indicator in .001 increments. It also has the spring unloader attachment.
I bought it 4 months ago and only used it at the North South Shootout at Concord and it works flawlessly. Can be picked up in the West Palm Beach area or it can be delivered to NSS during speedway. After speedweek it could be picked up in the Charlotte North Carolina area or back in the West Palm Beach area. Or buyer will pay shipping. $1400 firm.
