Smile Ring and Pinion Question

Will ring and pinion gears for a dana 44 fit in the dana 44 IFS? Also, is it okay to run a lower gear in the front? for example a 3.89 in the rear, and a 3.92 in the front.

by ifs you mean twin traction beam,no its got a different style carrier than normal reverse rotation dana 44s.about the gears,something that close is fine.there is a problem with a wider gap that would make your axles fight each other and break something like running 4.10 front and 3.92 rear

Actually you can use the ring and pinion from a straight axle Dana 44 in a TTB Dana 44, they're the same design.

The ring and pinion for either design Dana axle is the exact same so yes, you can put Dana 44 gears in a TTB Dana 44 with no mods, but you'd want to keep the ratio's something like 3.55 front and 3.54 rear, 4.10 rear and 4.11 front or vise versa.

With 3.89 front and 3.92 rear, you might destroy the t-case. The guys in the offroad section can help you out quite a bit on this if you need more info.

I always thought that as long as you don't go over 2-5% difference you won't destroy anything..

That might be, but I've seen people running those gears I mentioned before without any troubles.

You can make up for a small difference with tires size. A small difference won't hurt if it's only used on dirt or low traction surfaces. But on dry pavement (where you don't need to run 4x4,) something is going to suffer. U-joints are usually the weak link. They will get hot and loose their lube.

I can't tell you how much I hate it when that happens...

I've actually heard that a 1% difference is ok. So 3.89 and 3.92 *should* be ok. You shouldn't engage 4wd unless you're on a slipperly surface anyway.

Also, don't forget about the carrier break in the Dana 44. When you cross the 3.93 line, a new carrier is needed. And yes, I've heard the same thing about the Dana 44 TTB and solid Dana 44 gears being interchangeable.

Last, IFS is different thing altogether than TTB. When you use the terms interchangeably, you confuse people.

A couple more questions, Can you use standard rotation gears in the front end. Also what is the pinion spline count for the front and rear ends?

Hey what size tires are you running on your 1980 shortbed with the t-18 tranny?

IS the front differential reverse rotation ring and pinion or standard rotation?

44's

Studebaker used the Dana (Spicer) 44 for 50 years. There's an obsolete Studebaker Parts Store (SASCO) in South Bend, IN that still has parts for this rear end.

The Nissan Titan also uses the Dana 44, as do certain Jeep Models...and prolly others, too. Titans have ratios of 294-1 and 331-1.
