Hey guys
I'm a new member from Oman if you know where that is

Cherokee cars is our life over there


I just bought a ring & pinion 4:56 from Amazon ( alloy usa ring and pinion )

And I don't really know what is the use of it and what does it do ??

My tyers are Copper cobra size 31


Will this ring and pinion give me more acceleration then the stock stuff ????



And thank you a lot

 

O man! You got some learning to do. Lower gears will return you to stock power with bigger tires installed. 4.56 is going to be overkill for your 31's.

 

So you're telling me that this ring and pinion is no use to my 31 tyers??

 

I'm sure it will be fine..torquey as hell probably....but you do realize this isn't something you can just slap into your axle with yourself without any prior knowledge, right?

 

Yeah my friend I'll take it to a workshop

And I'll tell you what was the result on my 31 tyers

Thanks a lot for your participation

 

No, thank YOU for your participation.

 

Top speed: 63mph.

 

Better have some bigger tires shipped over too.

 

I realize that the desert in United Arab Emirates will swallow a vehicle whole.

I think that gear range may good IF most of your driving is desert and dunes (deep, soft sand). However highway speed will be severely limited and consume more fuel (high RPM's).
32" would be a better size for that gear range for both dunes and highway.

 

Jam, is that a calculated result or a guesstimate?
Oman, Oman is a dry hot climate right? Welcome to the forum. For future reference this question would go in the modified cherokee tech subforum. OEM Cherokee tech is for questions regarding the stock components, usually centered on fixing what broke, information for restoring something to stock spec, or what might be the cause of this problem/noise/leak... Again, welcome to the forum.

 

A complete guesstimate... I'd think it's close tho.

Oman, you purchased these not know what it would do? May I have some money? I need some jeep parts.

 

Is this accurate top speed to my car with this r&p???

 

Yeah also in Oman
90% of my trips is to the desert and dunes

Many thanks to you

 

Yeah it's very hot in here ..

Thank you mate

 

Your stock pinion spins 3.55 times to one rotation of the ring.

Your new pinion is going to spin 4.56 times to one rotation of the new ring.

It doesn't seem like much, but your rpm's are going to drastically change with the same size tire.

My guess of 63mph/101kph is a guess indeed. But don't expect your top speed to be more than it was.

The only thing you'd gain from doing this, is torque out of the hole. But a better chance of breaking other things if this is your plan. You're going to "redline" faster than you'd finish a quarter mile/.4 km.

Still not sure what your plan is.
