Hello all i just have a couple questions for those with exp...

01 5.9 magnum, stock except for SCT (Thanks a million to Suan), Exhaust..
truck is 2wd but id like to put a 3inch body lift and 305/75s on the truck for APPEARANCE.. However, im going to do as many mods to the truck for pure performance and acceleration as i can. EXAMPLE Hughes top end kit, HS 1.7's, 14x3, edelbrock shorty headers etc etc.
The only thing im not sure about is rear gear size.. Id like the best acceleration i can get with a 32 to 33 inch tire, and im not afraid to lose top end for them. Any ideas, suggestions on size, brand?

 

Based on what you want, i'd say 4.56. 4.56 is a good all around gear for 35's, so with 33's, it would really be nice for low end performance.

 

i was gonna say 4:56s also, 4:10s are good for 33s but 4:56 would give ya a little more get up and go, but i dunno what they would make you sit at when cruisin on the hwy at 70mph.

 

I drive about 30 miles round trip a day to work. when we go outta town we take my wifes tahoe so at 70mph i really could care less... i wanna get down a 1/4 mile track as quickly as possible in a truck i drive every day. call me selfish lol.

 

4:56s then bro. should be just right.

 

For what it's worth, I checked today as I drove in (because I get asked this alot). With 35" tires, 4.56 gears, at 75 mph, i'm doing about 2350-2400 rpm. So with 33" tires, you could expect another 200-400 rpm I would estimate.

 

Thanks for the info Silver, as far as a performance(acceleration) standpoint, would the 456's be the best option? ill probably run 285/65's on my stock 16's which stand at 33.1 inches tall. if i like the look i wont go bigger. Just want gears that will give me a quicker 0 to 60 & 1/4m. the stock tires are way too small in my opinion and i just cant leave them on there even if they do give you better mpg.

 

4.10's would keep your engine at approximately the same RPM as stock gears/tires. Going to 4.56 would give you a bit better acceleration off the line.

 

Sweet so ill go with the 4:56's. Thanks guys, now any idea on where online i can purchase them, or brands? no place locally has them so im forced to go online.

 

Randy's Ring and Pinion, and get the Yukon gears.
