I am debating on getting 4.56 gears for my truck. 2004 Dodge 1500 5.7L Hemi 4x4. Now, I was on this website airram.com, and it is giving me these options: OPT#1: AAM 9.25 FRONT GEARS / AAM 10.50 REAR GEARS additional $550.00
OPT#2: AAM 9.25 FNT GEARS + MAST INST KIT / AAM 10.50 REAR GEARS MAST INST additional $960.00
OPT#3: ADD AAM 10.5 TracRite REAR CARRIER TO ORDER additional $489.00

SUGGESTIONS??

 

None of the above. With a 1500 you don't have a 10.5" rear axle nor do you have a 9.25" front axle.

You have an AAM 9.25" rear axle, but not the same 14 bolt, 33 spline as you display in your post.

You need a gears for a front 8" IFS, 10 bolt, 29 spline axle and for a 9 1/4" 12 bolt, 33 spline rear. You should also have the master install kit. LSD would be an option...

 

Awesome! You know any good websites?

 

Hammer: Did you mean a 31 spline for the rear? I am assuming you did, but wanted to make sure.

 

Yeah, probably a typo. The 2500 9.25" front is a 14 bolt, 33 spline. The 1500 9.25" rear is a 12 bolt, 31 spline...
