Default Truck geared too low.

Hello I find my ranger is very low geared which is great for shifting heavy trailers but not so good for long distance motorway work. In the brochure my ranger is listed as having 4.44 gears whereas the newer models have 3.73 gears.
I've got the standard 29 inch tall tires on, do you think the truck will drive better with 31's on or will the difference not be noticable?

in your case the 31's would help with our gearing. I dont think you have 4.44 gears though should be 4.10's

UK Ranger....could be 4.44. But never know. I don't know those UK trucks all too well........yet. lol.




Gears are expensive thing to swap around....gonna be quite a few quid to get done. Ways you can manipulate the effective ratio to be higher geared: Higher gearing(numerically lower) or taller tires. Making the jump from 29" to 31" would make enough of a difference to feel and notice.

What's your current ratio and the specs on that Turbo Diesel?? Like bhp and ft/lb's of torque and at what RPM's? What's the redline of the engine? Things I've always been curious about and would help in this situation.

'09 Aussie Ranger axle ratios:

Auto trans: 3.727
Manual trans: 3.416

http://www.pressportal.com.au/news/9...009-02-20.html



**keep in mind, if you're using the Sticky thread here on FRF for axle ratios, it may not be accurate for anything out of North America. So keep that in mind.

Got the brochure in front of me now with fords official figures in.
Rear axle ratio 4.44
Maxium power 80kw (109 ps) at 3500 min (rpm)
Maximum torque 266 Nm at 2000 min (rpm)
The 3.73 gearing is on trucks built after 2006.
Thats pretty low geared for the small tires thats on it

Tiny tires + torquey diesel + pretty deep gear = FUNFUNFUN wheeler!!! hahaha. Yeah, that's a ton of power being put to the ground way down low. Wonder what the crawl gearing is in that thing. Must be really darn impressive in 1st and 4low. While it may be geared pretty low, it's possible that that's where the engine is happy and efficient. Don't know much on the 2.5/3.0 diesels yet.

If you can fit bigger tires, do it when you need tires. Then go from there. 3.73 will help ALOT.

I'll get the taller tires and be happy with the gearing as it is. Its nice to know the gearings capable of handling taller tires better than when peple fit big tires and lose all there power. I've been told the Ranger I got is better for towing than than newer one, this must be why and towing is what I bought it for.

wow, i wish my gearing was that deep! i have the opposite issue, my 3.73 gearing is great for commuting (stock 29" tires) but my box trailer really loads it down. ive thought about going to 4.56, i dont think 4.10 would be quite enough of a change. with my trailer is all about wind resistance (frontal area) the traler itself is only 1,000 pounds empty and rarly has more than 1,500 in it. fuel milage drops from 19.5 (truck itself) to 10-12 when towing. and i stay under 55. top speed with the trailer is about 72 but the truck will do 90+ not towing. in your case id just put bigger tires on it. it could probly handle 32's.

what sort of trailer is that? my ranger is rated to tow 2800kg which is alot more than I tow now. I used to tow a 28ft long trailer with my last pickup and this one I got now is alot better tower. Its worth keeping under 60mph towing anything though mate.

its a 6x10 haulmark, its 6' interior height floor to roof, so outside its about 8' tall overall. it has a V-nose front but still catches alot of air. i have a cap but its not tall enough to act as a wing to deflect the air hitting it.

I used to have a trailer like this when I was in a different business. It was 12 ft x 7ft x 6ft internally and real heavy unladen. These days I only tow caravan trailers so never tow much more than about 1500kg.
