Was thinking of getting 3000 gsk for a while now but thought I should see what it had before I spent my hard earned money. Well I left it in first and to my surprise truck went all the way to 3200. It didnt run great at 3200 but it en fine at 3000. Do I already have springs or can this be done with stock equipment. thanks

 

My truck does not have it

I can tell because when i run it hard it rather defuels at about 2400 rpms at fifth gear, yet it does fuel hard on all other gears to about 2800-3000 rpms, after that it just seems to bog down.. IF you have any of these syptoms, probably no GSK..

I got an auto so I dont know about 4th I would be going way too fast by the time I got to 3000. Maybe I'll try it in second toay on the highway and see if I get the same results

 

no you don't have it, my stock 215 pump would free rev to 3500. the gsk fuels much harder on the big end.

 

How many rpm's does it go to if you just mash it in gear? I doubt you have a GSK yet.

put it in third gear, then hammer down...if it falls on its nose above 24-2500, you don't have them. It will slowly work it's way up to the redline if it doesn't have the springs.

If it wraps right up with a load on the engine, you have the springs.

thanks for the input I'll try it at lunch
