JC Whitney springs ok to use????

[Vetteman61]

I have 4 inch blocks in the rear, but my original springs on my '87 k5 have sagged super bad. I have noticed JC Whitney sells original replacement rear springs for K5 blazers, but I'm wondering if the quality of these products is good.
They seem reasonably priced.

Thanks,
Brandon

if you're going to change out your springs, consider your other lift options: shackle flip and lift springs.

lift springs might be the ticket for you because you can get a 4" lift spring for a good price and do away with your lift blocks, thereby reducing axle wrap.

shackle flip will be more work and still require you to replace your rear springs if they're really bad, but will be the best way to do a 4" lift out back.

Colby brings up good points. You asked specifically about the springs though so lets talk about that. For their price those springs are okay. I have ordered springs from them and so did one of my friends. The two sets were obviously made by different companies but both seemed fine. I havent broken one yet, neither has he. There are other springs out there though that are of much higher quality and construction. I think that a company called Deaver is all the rage right now. Exscuse the spelling if I got that company's name wrong.

If you are looking for stock springs no need to look at Deaver. They make about the best spring around but you will absolutely pay for their quality. you;d be looking at about $700 for rear springs. I'd ditch the block and get a set of 4" springs from Tuff Country.
