4.88 vs 5.29

Why do I want 4.88s over 5.29? Or the reverse?
Im going to run 35s. Thanks

 

Probably gonna find this thread interesting

Thank you!

 

5.29s

 

But why

 

You don’t.

 

5.29s
Just because.

It’s just better.

 

Why: Options for additional tire sizes, the RPMs are still very reasonable, they're the same price, they are amazingly better when towing/crawling, and they are just overall awesome. I have them, I'm running them with 33.4" Falken Wildpeaks, and I couldn't be happier with all aspects of it. With 35's, I'm not sure where the question is. Do it once, don't look back.

 

It tows better. Ive gotten better MPGs. Unless you want to go over 95 mph Id do 5.29s.

 

Can i still do over 95? (I live in wyoming)

 

Wyoming still has speed limits...

 

LOL...In Wyoming, on the high plains last trip I set the cruise control at 92 mph...after an hour I had to take it off because I came up on another truck...

 

I always answer yes to this, but my truck is tuned and has the speed governor removed. Based on other people's experiences the truck will limit itself to 95mph, however if that is removed the truck can physically go well beyond 100mph with 5.29s.

 

5.29s...might as well go big. What if you want 37s later?

 

4.88s are for 31” tires…


I’ve got 5.29s with 34” tires, and there is zero regret. RPM are a couple hundred higher at Oregon speeds, but that hasn’t negatively affected a single thing.

Another thread with a nice gear ration/RPM calculator so you can run your own numbers and see that we’re all right! Lol.

My opinion, I felt that the pinion on the 5:29’s was too small. I have 35’s and the 4:88’s feel stock to me. However, a lot of guys here love the 5:29’s and I have not heard one instance of fatigue or breakage even with hard wheeling. 4:88’s stock feel; 5:29’s more tugging in the shorts.

 

Love my 5.29s with 35” Toyo MTs!

 

Mine governs out at 106 ish I think? But yeah we got long straight empty highways. So I do 90-120 a lot depending on what’s happening.

Are there any gears available between 4.88 and 5.29??? 5.13s???

 

Negatory

 

Yea I don't understand the claims of topping at 95 since obviously it's not limited by the speedometer itself and must be referencing rpm or something to conclude the truck shouldn't go faster? Like I said, I've never had any issue going any speed but I had the ECU flashed before I regeared. I'm at 2650rpm at 85mph with 35s.

5.29s are definitely the way to go, you have massive amounts of torque, marginally higher rpm but the engine isnt working anywhere near as hard. 4.88s are pointless imo unless you're on stock tires (even then though). There is the argument of a smaller pinion with the deeper gears, but I and plenty of other supercharged guys have never had an issue. The 10.5 diff is beef.
