4.56 to 5.13-D30 vs D44 front

Is it worth it to change from a 4.56ed D30 front to a 5.13ed D44 front?

I'm running 35's with a 4.0 and 5 speed manual.

Stronger knuckles, lower gear potentials, stronger tubes, stronger ring and pinion, etc.

IMO, yes. Of course take a look at the HP30 too, 4.88 is low enough for a 4.0 5spd with 35's

I'm thinking of going to 37's & didn't think 4.56's would be enough gear. It would be $1200 to regear my D30 front & D44 rear with a minimal change to 4.88's (only a .32 difference). So I thought if I spent $1200 for a minimal gain in ratio I might as well look at going the D44 front option allowing me to aquire 5.13's. It's probably more cost effective to stay with 35's & 4.56's.

I thought that the only stronger point in the D44 front was the pinion?

A) Why not do some learning and research and regear yourself, cuts alot of costs, find someone else around your area who has experience to give you a hand, it's really not too bad as long as you take your time and look everything up. Start here.

B)If you're looking at 37's than the D44 won't be strong enough to really support them, start doing much research, gathering of parts and tools, and what it takes to run D60/D60 or D60/D70 combo. Go big or go home. Start here and here and here.

C) On a D44 front, the knuckles are bigger, the ring and pinion are bigger, the axle tubes are thicker, and you can run the 5-760x u-joints. If you upgrade the unit bearings then the axle shafts can be 30 spline outer and inner and you then have stronger unit bearings and axle shafts.
