okay boys as yall know i need to fix my rear end... and in doing so i will be getting these....http://moesperformance.com/index.php...oducts_id=1134 its the motive 4.56 and master install kit...my question is what is included in this "master install kit" as moes doesn't describe it...also these "c-clips" some of yall ride with out what are they really and what do they really do? are they clutch pack retainer clips? should i buy new ones and replace them while the tech has my diff open? so they dont fall off and screw up my new stuff....what do they run price wise? what else is in there that needs to be considered? other than a dtt i dont have the extra coin for the dtt or it would be on the list....i plan on getting the order in so i can have my truck done next week the tech said it would take less than a reg business day....what else should i expect?.....

 

Master install kit has all the bearings, races, pinion seal, shims, pinion nut, ring bolts and crush sleeve.
The better kits come with Timken bearings.


Have them yank the clips out, many people have run without them for a long time with no problems.

and when the time comes, I'd run an Auburn LSD, clutch types lock up faster than the DTT. ALL the 4x2 "track guys" I know opt for the Auburn for faster times.
DTT for a 4x4 or 4x2 off road truck, Auburn for street and track. (yeah, I know I have an off-road truck and an Auburn, it works...)

 

Good post jusjay my diff is whinning again after 2 years from being rebuilt from the dealer. Im thinking of getting this kit from moes also.

with 456 gears . I have a couple questions
Will it improve gas mileage or use up more?
Does this kit have everything i need ? I know i still need oil.
I use my truck for street. and also want to hit some simple trails im hoping it will help with off road. My truck is not a 4x4 and i want to take it hunting hoping i wont get stuck.
Sorry dont mean to thread jack.

 

Probably the most asked question after "what size tire..." is about gears and MPGs.

Is probably in this section a couple of hundred times at least. But to answer your question, you should see a small improvement in MPGs in town and combo driving and maybe a slight one or two mpg decrease on the interstates, usually up over 70 mph or so.

Probably the single best mod for getting power to the rear wheels and extending the life of the transmission.

You may spin a tire a little quicker off-road however, since the rpms are higher at less throttle.

A good aftermarket LSD is the key to traction (especially with a 4x2) off-road...

 

You might add axle seals while you have it apart, they are not included in the Master Install kit. If there is any way for you to include a differential whether it be Detroit/Auburn you will have saved yourself a good deal of money in the long run. My shop did mine in four hours.

 

how much for the axle seals i thought those were included in the master kit maybe im wrong and hammer i think the timkens come in the kit also....i wish i had the extra coin for a diff lsd and auburn what ever is best but for now im just gonna have to do....i know its like beating a dead horse but what do these clips do...or is there a technical name for them i know reg c-clips hold the axles in....

 

is going to a dealer a good route to go to have gears installed?

 

your local dealer probably has one guy that specializes in drivetrain/suspension work. they will more than likely be capable however these jobs or more commonly seen by a tech in a transmission/drivetrain shop. A transmission speacialty shop is usually the best bet because there is usually a tech there that does spider gear work all the time which would make them extremely familiar with rear differential rebuilds

 

I only ask cause I don't wanna mess with warranty and deal with their 'oh the antenna popped off cause you installed gears' cry. I'm at 12,000 miles and am looking into the 4.10s for my mega cab. anyone know of any good shops in the so cal area? specifically orange county...

 

The correct name for them is "clutch pack retaining clips".
Yes, Moes master install kits include Timkens.
