I have trx450 2008 and i want to buy hot cam stage 3 but what i need to know, i can install this cam with stock shim & valves , or i have to upgarde all of them?

Says on their website it uses the stock valve springs but doesn't mention the valves themselves. I would think it would be fine. Shims are shims there aren't performance versions of them. I don't have experience with the stage 3 but I had an 06 with the stage 2 on stock springs and valves last summer and it was a good upgrade.

It will be fine, most builders will upgrade the springs witha a stage 3. But while you have it apart its not a bad idea to get a spring kit. Its not hard to do and I believe the KW spring kit is only around 150 bucks
