who has bigger than 60

 

Hamilton's springs or there are dual vlave spring kits out there.

 

no need for them unless u got some serious turbo's huh

 

or if you want to turn some rpm, In nick's and myselfs case were both turning 5k and need a better spring/retainer set up.

 

ok, i've got stock retrainers and keepers...

i want to turn it a little more since i think my 3.73s are crap....

Currently i can rev it around 3200rpm with no load but it stops around 3000rpm-ish while in gear & under load...

let's say i'd get 4k GSK ??? i'd be able to rev 4000rpm under load ?

 

the highest underload rpm I could get with 4k's was 3700 - 3800 and free rev to 4000. anything higher than that on my pump was very touchy to drive

 

Can you expound? Have you hit it harder than that? (like a 5k kit or what?)

 

Im wondering where all these 3.73 ratios are coming from all of a sudden? I thought we couldnt get 3.73 in our trucks without switching to a 3rd gen axle

 

currently have 5k springs in my pump now, I played around with the 4k's in my old 175 pump.

its just a ring and pinion swap away

 

i'm pretty sure my 3.73 are OEM... or maybe i've got it wrong at least it's not 4.10 like i thought at first... i got the build sheet for my truck somewhere and it says 3.73 i'm pretty surre...
