What would be a good gear ration for my '91 3.0L V6 4x4 pickup with 31's.....it feels like to gearing is too tall right now, I want to be able to use 5th and 4th to go uphill instead of 3rd.

 

What is your ratio right now?

 

I don't know, I got the truck from a friend and I don't think he changed the ratio at all....so what ever stock is...oh and it's a 5spd manual

 

Even though a lot of folks call the 3.0 the 3.slow, it's still a capable motor and 31s shouldn't be giving you that much performance decrease. Maybe your engine is down on power? Are you expecting too much? I have a 245hp V8 in my other truck and still have to downshift if it's a steep grade (probably don't HAVE to, but lugging the engine on grades is a surefire recipe for short engine life.) Your stock ratio is probably 4.10. So, for 31s 4:56 would be about right, but it's a lot of money for so little gain.

 

Could be stock 4.56's if the tires are also stock. In which case maybe you want 4.88's. Check the info plate for the gear code.

 

Yeah mines 4.56, & if iwas driving alot of hills i think i would prefer something a little higher ratio,maybe 4.88.
You need to read the Vin label on your firewall & tell us what it says.

 

I believe the 4:56 ratio only came with the <gasp> automatic that year... But I've been wrong before...

 

nope, 4.56s came with all trucks with 31" tires and manual transmissions. 4.88s came with autos and v6 engines only

 

Did the truck come stock with 31's or did your friend put them on there. If they weren't stock, I would think the stock gears are 4.10's. I've also heard that some trucks came with 4.30's. There is a guide to find out what you have by your VIN on offroad.com or 4x4wire.com.

 

My axle code is G294, which I think means the gear ratio is 4.10
