Class 8 9" Rear

[class7s]

What width should I run, there is a Currie 62" for sale here? But is this wide enough?

[Ramsey_ElWardani]

Not even close. Start around 74".

I feel the correct width for a 8 truck form the out side of tire to tire should be from about 84" to 87" and about 2" less in the rear.

thanks you just saved me from a stupid purchase

OK, just off the phone with Currie. This is what I have come up with.

9" Ford Rear (74" wide)with the extreme housing, 35 spline axles with any ratio I decide
1350 yoke, 5/8" studs and disk brakes for basically $3200.

Should or shouldn't I?

TIA

I dont think 35 spline is enough for a 5000lbs class 8 IMHO...what brakes is that with??

[John_Bitting]

I would run a full floater rear end. Check out Tubeworks, Currie makes a full floater, Desert Specialties does, Call Baja Concepts, I think RacerX sells a nice one also. You will not want anything less on a class 8. I was told 35 spline axles would be alright not the best but should not be a problem.

Have you built the front end of the truck yet? If you havent, you might whant to becouse this is where it is critial in fitting all the stuff into a small space. Ie, shocks, bumps, brakes, steering, arms and on and on. My point is the front usally sets the width of the truck and the rear is just a little narrower.

Hope it helps.

Also check out Mittler Bros. Rear ends, very good price and quality.

Just got the phone with Tubeworks, it looks like that is the direction I should go if I do not find a used one. The total price is going to be bewtween 8 and 9K for everything. I guess I am going to have to sell a lot of computers and photos.

we use a tubeworks rearend on our 7s with 35 to 40 outside axle that came from tubeworks which we recently broke at tt 250 so you might want to check on a 40 40 for the extra tourque

if you still need a rear end give me a call, i have 40 spline parts and we can build one
