Our car is 3200 pounds with a stick and a MW aluminum spool. We ran a best 60' this summer of 1.38. Sounds like the clock is ticking.

LOL? I was in Orlando some years ago and walked by a SS Hemi car. They were changing the center section in the rear. The axles were sitting behind the car. They were a shiny grey, unlike any axles I have ever seen. I commented to a friend about it. He walked over and picked one up. It wasn't steel. _________________________________ Andy Stone 1102 A/S 1112 SS/C |

Ed, what Haas said to you is right, but, as is said here before, apples and oranges with what we do and a Pro Stock car, I'll never have to worry about the later! ![]() As for longevity in one of our cars, when I finished my car in late '07, I put an aluminum Moser spool in. Tim Irwin told me at that time that they had previously had breakage problems, but, got it fixed. I have had the rearend apart at least 3 times a year since then. The axles are as tight as day one with no visual signs of problems. Without gears installed and dial indicator check, it still only has .001 runout. You be the judge........

Wade, what will live in a foot braked 283" stocker won't necessarily live in a trans braked SS car. When I pulled that spool out it had .004" run out. Jerry Hass was with that Hemi SS car because he built it. Not only Pro Stock cars.
I have talked to others that made only the light spool & ring gear change as I did, and nobody found any gain. I'm usually between 1.29 & 1.34 in 60' with the steel spool, exactly the same with the lightened ring gear and aluminum spool.

Mopar Jeff---Most Comp cars weigh considerably less than a Stock/SS car ---pro cars all weigh 2350 min wt- MOST COMP cars weigh about 1180-1600 for a dragster and from about 2300-2900 for a door car although some are a little lighter or heavier depending on the combination/class---granted most pros have 1190-1300 hp but they are spinning the tires a bit at the hit with the power they have and they all have 40 spline set ups too--Most pros run the 9 1/2 inch Dewco gears along with the Dewco spool---Some run MW or Strange and a few use a Moser spool---The high HP Comp LIGHT WEIGHT cars all use 40 spline parts mostly Dewco some also use Strange/Moser/MW too- Those lightweight cars weigh anywhere from about 1100-2400 pounds weight wise--- no comparison to a 3500-4200 pound Stock /SS car they also use Carbon Fiber or aluminum drive shafts Again NOT recommended for HEAVY cars.--I'm not trying to convince ya on what to run just merely trying to enlighten ya on why certain types of cars utilize certain kinds of parts. If it works for YOU great but ya better be diving in that rear end every weekend or so to check for any signs that might predict failure--Those 10,00 RPM launches are brutal on drivelines--I honestly believe that the typical Stock or SS car RARELY pulls the rear or axles out to check them and if at all maybe one time a season whereas we take the driveline out after every other weekend to check !!! If alum works for ya or Titanium is legal and ya don't wanna run steel OK---If ya are happy with Steel stuff OK too----It's all in your combo what works for me may not work for you and vice versa-- Your still not looking for that coupla extra thousandths which can translate into hundreths tho like a comp or Pro car is--Comp 387

Ed wright that 1.29-1.36 60 foot is .06 in ET which in a Comp car translates to about .12 in ET at the 1320----No Comp car is gonna give up a TENTH +++ to run a steel setup versus an aluminum/ liteweight axle set up--- never gonna happen---Comp 387

I built my car with a complete MW Dana 60 w/ CM tubes and used the ultra-light 40 spline axles. I wanted the 40 spline for the strength in a 3160# -3320# stick car and as Stocker axles are long (compared to a comp car for example) I wanted the weight out. I bought with the lightened ring gear and the light-weight STEEL spool as I believed an aluminum spool was too much of a strength compromise. I can not document the ET savings as I have always had it in my car. I do know that I have NEVER had a rear-end problem and have changed gears several times and they always look brand new. Same with the axles.
So is it worth it? I don't know but the piece of mind is priceless. Of course some people can't substantiate the cost difference of anything pricier than Moser. And the stories I hear are an aluminum spool and driveshaft are crucial on the small engine cars (300" or less).
