I have a 2004 trailblazer, i just bought a hpd pipe for it and am wondering if anyone knows what primary, secondary springs and also clutch weights i should use at the altitude of about 4500 feet.

 

I forgot to put in that i am not looking for top speed, do alot of playing a light trail riding, it is for my wife!!! She wants good take off without the wheelies. I was told a polaris orange primary, gold secondary, and as far as clutch weights???? She just wants to keep up a little better with me on my stock 400. And i really don't go for top speed, but a good bottom and mid.

 

That HPD pipe is what we have on ours and the only setup I have found that works good is what they recomend(red/yellow primary,gold Polaris secondary and 10-58 shift weights)I tried other lower engaging springs and it gave me a bad dead spot on the bottom end.

 

Is that for higher elevations? And where can I get that color of primary spring? I'm wondering if it will be easier just to buy their kit?

 

u can buy the springs and weights from hpd...i have an orange spring if u wanna go that route

 

is 10-58 too much for high elevations? I went ahead and ordered the hpd kit for 90 bucks. I guess i'll try to get it right on my trailblazer 400. Anybody have any suggestions?? I am putting a hot seat pipe on it, k&n filter, and that is about it. I want good bottom and mid and stay about the same on top.

 

Take your stock weights with you and if the 10-58 doesnt do good change them outt.
