I don't think you'd break this,, it's surviving 790horse, 1.2x sixty's in a 3000 pound chassis, tansbrake, wheels up launch and tripping the 60' timers with the rear tires


It's only

On the more mild (and affordable side of the 9"
I've beat on the 9" in my 66 with 666HP, big slicks, Iron aftermarket centersection, Richmond street gears, Dyneer No-spin locker. No failures yet with 3650pounds, 1.4x sixtys on a transbrake launch. EXCEPT axle,, 2 Strange 35spline axles, and one Dutchmans axle, now I'm running Mark Williams axles in everything and (knock on wood) I can't seem to tear them up.... waiting for the next weaker link to surface.

There are a lot of 9" haters out there and the little extra HP it takes because of the pinion placement, all sorts of technical excusses to not use a 9", BUT the fact remains the 9" has become the 'SOP' for hotrodders and racers. Parts are more plentiful and engineered / re-ingineered and re-re-re engineered that the 60 or so years they have been around they are about as bulletproof as anything out there,, and cheaper than anything else to build. (With 'cheap' being a relative term obviously).

The 9" is has become like the Miscrosot of rear ends... just about EVERYBODY carries a program for them,, and just about every parts house has the pieces to put one back together if something fails. The aftermarket proliferation of quality ad affordable pieces make the 9" a no brainer IMPO if your starting from scratch. Pick a wheel, then have the rear built to fit.

You get what you pay for,,, anywhere from around $1300 to $3800 depending on internals, brakes, bracketry, axles.. bla bla bla




BTW, keep in mind not all "14 - 16" tires" are created eaqual. I owned a set of MT Sportsmans once. A little 380HP 355 would blacktrack to 1/2 track with a best of 2.15 sixty foot times. A change to a Hoosier QT street tire was good for nearly 1/2 a second to the 60'. Hard as nails 'built fore looks' street tires just aren't going to hook and hurt parts. Changing from the MT Sportsman to the Hoosier QT was good for 3 axles, 2 u-joints, a driveshaft........... It's a very slippery slope

Thats different that Strange uses the two sizes of bolts. are they stagered 1/2 and 5/8 or 5/8 and 3/4 threads.. not much room for a socket in there. I spent about an hour last night looking at Mark Williams # 24 catalog. very very impressive products they have there
