I ordered a 3gsk spring kit for my 98 12v and the P.O. told me that it had a #10 plate. So I get the AFC housing off and it has a #11. So I'm reading the directions and it says not to install unless you run a #10???? says it will run worse than stock, opinions? has anyone run the #11 with a 3gsk? should I just put it back together and grind my stock plate? need my truck for work and it's down right now. One more question, if I were to put it together without the 3gsk could I slide the 11 all the way foreward until I could grind my plate?

 

anyone??

 

put the 3000gsk in.....the plate....try them both....the 10 will run good but the egts will go past 1300 so fast you won t be able to see it....kidding you ll see it.

 

i don't recommend sliding the plate full ahead, it will make for some high egt's, put the gsk in and plate in stock positon for now.

 

You could lose some power, but that can be fixed by adjusting the governor lever arm; so go ahead and put it in,a nd if it loses power, youll have to adjust your governor lever arm, and if it doesent, then its fine. Mine lost power with my #5, after i put the 3k GSK in, and adjusted the governor lever arm, and now it runs great again.

i run a # 6 plate with the 3k spring kit,it runs great.First installing the gsk i didn't notice much difference until i backed off the star wheel 10 clicks,then the truck came alive,great fuel economy also, usually 22mpg combination of city and hiway driving.
