What do you want them for? The stock units can handle some pretty big revs.
If you insist though, Crow can sell you a set of smaller springs that go inside the stockers for around $100. That'll give you doubles. Part number is 4220.

so they are just smaller springs that go inside the stock springs making it 2 springs? thanksPaul Smith wrote:What do you want them for? The stock units can handle some pretty big revs.

It's really not needed unless you're going to be running over 8000rpm.
And if you're revving that hi its a pretty much drag dedicated car because its going to need a massive cam too.
If it aint broke, don't fix it.

Unless the stocko springs are a bit saggy and don't meet their specs, there realy isn't too much reason to upgrade. If you are going a little wild with cam selection, just get some used Holden performance 186 springs, they should be quite common at machine shops and cost next to nothing if the workshop is sensible.

short answer yes. They will handle 8000rpm no probs. anything wilder and then you may need to look at something else. Trsut me when i say at 8000rpm its really screaming id be worried about taking them further at mid to high boost hahaha thats a helluva lotta work lol

I would be a little hesitant in saying the stocko springs can manage those sort of revs (7k+) as I have bent exhaust valves when my box used to jump out of 5th.
Probably wouldn't be a bad idea to get them checked for seat and full lift pressure before assuming they are O.K.
I have had my Yella Terra 186 springs for a couple of years and they do what they are supposed to. Straight swap with 20lbs greater seat pressure and 30 odd extra full lift.
