Hey guys me and my dad just pulled out the rear end out and we got the posi axles, clutch packs and all that out and cleaned everything up and my rear end is the 28 splines with the spider gears and i think the stock gears were 3.08s if i did the right math and i wanna put 4.10 gears in but i was told you cant put those in the stock posi??

get the carbon fiber ford racing clutch pack kit and yes you can put 4.10 gears in, I just did it a few weeks ago for a member on here....as long as you know the proper procedure to follow when installing gears, your fine, don't know who told you that you can't put 4.10's in??

Ok ill get those clutchs and it was a guy at a palce called lake performance and ya he said like the gear is to big when you go to 4.10s so you need like a eaton or auburn posi well thats what he told my dad anyways,,,

the 4 .10's will be a huge improvement and yes you can install them on a factory unit, I'd use the ford racing ones as they are user install friendly.....as for the injectors, with that mild set up you should be able to get away with stock injectors for now, best thing to do is assemble it all then have it run on a dyno with the a/f monitored at all rpm levels to see if it goes lean under heavy load, if it does and you have FP set to optimal setting and proper fuel pump then you'll know the duty cycle of the inj are maxed and at that point it'd be reccommended to upgrade and at most with your set up to 24's would be my guess
