Having gears installed this week and now second guessing myself. 4.10s with Tru Tracs will be installed and now I'm hearing that 4.10s are too much. Not really understanding peoples reasons, I'm not driving a Ford LTD.

'93 reg cab short bed, 302 (rebuilt in '20) MAF conversion, four wheel drive, 2 1/2 lift, with the E4OD just rebuilt to take 400hp/400ftlbs of torque on 32x11.5x15 tires and 3.55 open diff. Truck is a daily drive and used to haul and tow plus sometimes going off road. When the gears go in I'll check the rpms and adjust for tire height then. Right now at 55mph I'm at 15/1600rpms at 70mph 2100rpms. I'm planning something like a 34" or even 35" tire (11.5 or 12.5 wide on 16" wheels) will get me back close to where I'm now. Not exact, though round bout. I'll play round with it.

I tell them I'm going with a larger tire and wheels and what I use the truck for and still get "its too much". Whatchya's think? Not too much or too much?

 

As long as you have an overdrive gear, 4.10s will do fine.

 

Well, Ford thought they were too much for an F150. And if you're just trying to get back to where you are now, why not just keep it the way it is now? Spend that money on something else.

BTW
Gears with higher numbers (lower ratio) are physically WEAKER (more-prone to bending/breaking) than those with low numbers.

 

Thought bout it n you're right. I'm going to sell the 4.10s and go 4.56's. 33"/34"/or35" x12.5"x16" tire might get me back to normal operating parameters. How is that going to help with towing and hauling? There is no FRPP/Motive 4.30 gearing for the dana 44 IFS so 4.56 should do the job plus give me a little extra for the towing.

 

I hope you don't plan on towing very much then.

 

Explain please, new to this. This is why I posted the thread. No, I don't plan on towing a lot maybe three or four times a year if that. Going to be looking at toys next year - bikes, quads, jets skis, 24 to 30' boat or camper. Still, this will be my daily drive.

 

It won't. A 30' boat or RV would be a helluva lot too much for a '93 F150. It would be fine as a DD if you just maintain it, and get something suited to towing for towing. Like an F250/350. This is one of my F250s; the '93:

An F150 of this era already isn't set up to tow all that much to start with. A lifted suspension negatively impacts the stability of the vehicle, and larger wheels and tires will lower the cornering ability, as well as the effectiveness of the brakes, all of which are essential to towing.
