Shaftmasters Inc is here to answer your driveshaft related questions
Hello Forum Members,
We are a new “Authorized Advertiser” on The Mustang Source Forums with over 40 years experience in driveshaft manufacturing and repair.
Shaftmasters Inc. manufactures 3.5” and 4” diameter single piece internal slip style aluminum driveshafts for 2005+ Mustangs. These shafts features the following:
Customer reviews of our shafts can be found at the following links:

It has been our experience that an aluminum driveshaft with quality non-greasable universal joints will consistently balance better and run smoother than a steel driveshaft at the higher RPM’s produced by today’s overdrive transmissions.
All of our Mustang replacement shafts feature Free UPS Ground shipping to the continental US and are available at the following link:

What are the advantages or disadvantages to using the adapter plate or the new flange? Why is the 4" DS cheaper than the 3.5"? Will the 4" fit with no mods to my manual Gt with long tube headers X-pipe and 3" exhaust?
Thanks,
Mark

The advantage to using the adapter plate is ease of installation. We decided to offer shafts with a pinion flange because even though we have received no complaints about our adapter plate we know there have been other driveshaft marketers that have had vibration issues. So in order to ease people minds we decided to offer a shaft with a pinion flange. The disadvantages of a pinion flange is the fact that you have to reset the pinion bearing preload upon installation and if not done properly it can lead to major differential problems. As far as the 4" being cheaper than the 3.5", it is all a matter of component cost. 3.5" components cost us more than 4". We would like to make it clear that our "dollar amount" profit is the same on either 3.5" or 4". In other words even though the components for 3.5" cost us more, we still make the same profit off of either deisgn. As far as whether the 4" will fit your vehicle I can tell you that we have sold plenty of 4" GT shafts for factory original GT's and had no complaints, either manual or auto trans. If your exhaust and headers are larger than factory then you might want to take some measurements to ensure that you have clearance. Also, keep in mind that while the 3.5" is more expensive it does feature thicker wall tubing and is rated for higher RPM's and more Torsional Yield.
Thanks, David

Hi,
I pasted a reply in another thread last night, just noticed this question thread for driveshafts...just want to say up front looks like shaftmasters makes a good product, and anything that helps vibration will help everything last longer- the thing is often in magazine adds and dyno pulls you read of things like 20 hp gain with a lighter shaft...just was really interested in some technical specs on inertia/savings...thanks for any insight/corrections

is the 'WK squared' inertia number out there somewhere for stock and aluminum units? SURELY someone out there has got the numbers on these shafts...
inertia, rpm and time would give undisputable true horsepower numbers, but have yet to ever see any adverised...
edit- just for the heck of it, lets look at a rediculous 'driveshaft' :
a SOLID steel 4" bar 60" long accelerating from 0 to 4500 rpm in 14 seconds requires only about 3 ft-lb over that time to hit that rpm...if I did the math right...I'm tired, so definitely no guarantees there...
(3 ftlb*4500 rpm)/5252= about 2.5 hp peak thru the lights (HP tapers linear from zero at 0 mph to 2.5 at 100 mph). I'd venture to guess if solid 4" is 2.5 peak, the tube version is WAY under 1hp peak...
maybe Ive go the math all wrong, but Ive read claims of 20 hp savings and such from a relatively light piece of tubing accelerating to 4500 rpm in 14 seconds, and it just dont feel right to me...after running numbers for a solid steel 4" bar, now I'm really skeptical...is there someone out there that can convince me, show me where I messed up the math or whatnot...please
if the purpose is a better balanced/higher rpm shaft, then I can kinda see the draw to aftermarket shafts, but if its for acceleration it seems a kinda low return on investment to me...the 'save 20 hp' claims ive seen from some ads (not shaftmasters) are the ones that get me scratchin my head...
heres the formulas I grabbed:
INERTIA (WK2)
For Solid Cylinders: WK2 = .000681 pLD4
For Hollow: WK2 = .000681 pL (D24 - D14)

ACCELERATING TORQUE
For rotating objects: T = (WK2 )∆ N / 308t
Where:For rotating objects: T = (WK2 )∆ N / 308t
- T = Torque required (lb- ft)
- WK2 = Total Inertia of load to be accelerated
- ∆N = Change in speed (rpm)
- t = Time to accelerate load (sec)

We agree that some of the claims being made out there are hard to swallow. We do not feel comfortable making these claims ourselves. We do however have a few customers that say after installing our driveshaft they then proceeded to run their best times ever. Whether or not this is a direct result of HP improvement or simply the driver having more confidence in his vehicle is an open question.
As far as numbers go, we currently have a V6 3.5" diameter shaft being installed and tested by forum member "Billybix76". Watch for his post showing before and after Dyno results, they should be coming sometime shortly after this friday.
By all means the purpose is for a better balanced/higher rpm driveshaft. Also to replace what we consider to be a flawed original design. As of right now these vehicles are still relatively new but we have had customers say that their OEM driveshaft has vibrated from day one. As time goes by there are going to be more and more replacements due to necessity as opposed to performance improvement.
Seeing as our 3.5" and 4" shafts are equal in weight to each other and also equal in weight to the shafts offered by other companies. We know that our shafts perform as well as any aluminum mustang shaft on the market. When you also consider the fact that we have had not a single complaint (i.e. vibration, installation issues, shipping damage etc.) we feel confident in making the claims that we do.
Thanks, David

I am not a skeptic but I am let's say I'm very cautious about claims of no vibration with V8s and automatic transmissions. How many 3.5" aluminum shafts with an adapter plate, in a V8 with auto transmission have you sold?
Don't take this wrong, but it's easy to claim that there are no vibration complaints if you haven't sold any.

Hey Tom , haven't seen you around here much lately. I see you switched from the Diablo to the SCT , is that because Scott left them. He's now at another place a little south of here , since Steeda lost their tuner Sam , I may start taking my car to him down there ...

Quite frankly..........Yes
Very poor product support for Diablosport in my area. I am currently using Justin Starkey @ VMP Tuning and JDM - both use SCT.

As of today we have sold 20 of the aluminum shafts for the V8 with auto.
We have also sold 45 of the V6 shafts. We also manufacture aluminum shafts for Nissan 240SX and Toyota Supra MKIII and have had no issues with vibration there either. In addition we manufacture custom aluminum shafts for street rods, strip cars, pickup trucks, vans etc. All total we do manufacture 100's of aluminum driveshafts every year.
Thanks for asking,
David

Tom,
I will try to get in touch with some of our past V8 customers and see if they can provide some feedback. To be frank we consider no news to be good news when we sell a driveshaft. It is very rare that a customer will call up and let us know how pleased they are. But if they had a problem we would be the 1st to know. In the meantime we are waiting to hear back on an offer we made to forum member "LEO_06GT" about installing and testing a V8 for us so we could have a forum member testify.
Thanks, David
