So I came across this local ad, is it a good and deal? Is the install kit worth it?

I have 3.08 open differential right now, wanted to go up to 3.73 but for this price I think I could swing 4.10. I will be running stock tires for a bit, but then maybe upgrade to 265s when I put my new engine and transmission in.

98 f150 4.6 386 000 kms.

Thanks in advance

 

Price isn't bad for a new set with the install kit, but that's a really low ratio for the tire size you plan to run.

 

When I'm done building the truck, I am looking for pulling power (torque) and acceleration/ speed. I basically want a strong truck. I thought 4.10 would be a bit much, I still want decent mpg's lol. That price is unheard of in my area though

 

I have a 4.10 with 265/75R16s and I like it a lot.

 

It says any ford with 8.8 rear end....i am pretty sure thats not true because some 8.8's in rangers/explorers/mustangs/f150's have different splines either 28 or 31 spline, so i would make sure it will fit your 8.8 rear

 

How would I go about finding out what spline my truck has? Stupid question I know, but I don't wanna drop this kinda cash on something that wont work and that I wont be able to resell. Also, could I add limited slip (positrac) with this kit instead of having an open differential?

Thanks for all the help. Much appreciated.

 

It would probably be cheaper to just get a good axle from a salvage yard that already has LS and the 3.73 you are lookin for.

 

I would just do what buxton said...I'd upgrade to a 9.75 rear especially if you wanna tow and get it from a craigslist or salvage yard f150 with 3.73s and ls....way easier install too

 

9.75 rear end up grade will need the drive shaft too, or modification to yours.

 

True that but still cheaper and you'd have limited slip

 

Ok so there is no way to add ls to this kit? I would like to upgrade to a 9.75 but the prices up here are ridiculous. Also, if I buy another axle I would wanna rebuild it, so it wouldn't be cheaper lol. I am patiently putting in a whole new power train and want it to be strong, solid and reliable. Keeping this length of drive shaft would also be preferred.

So could I make this work with a ls? I am meeting him soon...

Thanks for all the help and in advance

 

yes you could but a limited slip or locker (a good one) is gonna be $600 bucks......are you installing this yourself?

 

I would like too. I like doing most of my own work, but I could try to find someone local to do it.

If I cant tell what spline my truck is I guess I have to pass on this deal?

I was just hoping with this kit for 250 then a ls or air locker for about 600 would still be a good deal imo- was trying to stay under 1000 in the rear end.

Let me know if there is a way I could find out if these will all work together (splines, etc). I have tried to research it but have to work overtime all this weekend

 

Just a heads up, if your not completely sure you can do the install I wouldn't risk it, it's one of those things where if something is slightly off all those parts you just put in could be shot and need to be replaced.

 

X2 on what pizza said....31 is the spline for the 8.8 rear in the f150s....but it's like 28 for some rangers and explorers ...this kit could work fine I just am unsure because it says it fits ALL 8.8's which I don't believe
