[OKGMC4]

My rack started leaking from both bellows and I’m not really sure why. It was rebuilt in 2011 but maybe the seals didn’t like sitting so long or maybe it wasn’t a good rebuild to begin with? Unsure. Anyhoo, it looks like C4 racks are getting rare because they are going for $300-$400 on ebay, parts stores can’t get them anymore, Turn One in Michigan can rebuild one but that starts at $375 with a minimum 2 week lead time. I thought I’d try my hand at a $30 seal kit but when I got to reassembly I could not get the short shaft back in without destroying the 4 square nylon rings on it. Believe it will take special tools to do properly. Plus no way to test it first and still don’t know why it failed. I found that a company called Lares in Minnesota produces new c4 racks with a lifetime warranty. Summit has them for $450. I hate to spend that much but might be the best option since used is so much. When it came time to choose between Flatout Engineering or Progressive Automotive for a crossmember I went with the one that fit my corvette rack. Since seeing you can get a tbird rack for $100, wondering if I made the right choice.
