Aluminum Driveshaft

[AF1JZ]

I see what your saying and it sounds like a good option. If i'm on road trips, my speed is usually around 79 mph (if caught, ticket is cheaper). But, correct me if I'm wrong, but what your saying is that the bonded center creates a lighter piece all together than a one piece? Sorry for all the questions. Once again, welcome back IJ and your help is greatly appreciated as for the rest of you guys.

 

[IJ.]

Lightest to heaviest.

1 piece Aluminium

1 piece Steel

2 piece Welded

2 piece Bonded

the 2 peice driveshaft's rear section is heavy because of the double tube with bonded rubber isolator.just replacing the rear section alone will drop some weight.

 

[AF1JZ]

What kind of weight are we talking about IJ with what you recommend?

 

[IJ.]

As I said before it's a personal preference thing as lots of people rave about their 1 piece shafts, I don't think it makes such a large performance increase as people believe.

My "guess" (this will be unpopular) Is that it's a bit of placebo effect at work, if it were something large diameter like a flywheel yes you get a much lower PMoI but on a 3" shaft I just can't see it!

Having said all that I had a custom true 2 piece made up using Strange Engineering parts and large 1350 uni joints so I know If I ever get traction I won't break it!

 

[AF1JZ]

Placebo, I like that. Probably true too. Can you attach the pics instead of the image hosting site. My server blocks those and I get red X's. Thanks.

 

[IJ.]

AF: They're actually hosted on my webspace so should display?
(They're large pics that I've thumbnailed)

 

[AF1JZ]

Yea, my server also blocks "personal pages". It blocks almost everything. I'm in a deployed location too, so they are extra careful.

my aluminum 1 pc made a noticable differance.my car is auto,so pretty much everything is much more noticable.as for weight,all you have to do is try bolting up the stocker on your back.not fun at all.one hand the 1 pc in there,very easy.stock unit has got to be more then double the weight

I've ran the JawsGear 1pc steel DS for many road trips, many drag races, many 130+ passes.. Not one vibration or complaint at all. If I could run a 1pc on my Tacoma I would!

 

[IJ.]

AF: Bugger!!

AF: Bugger!!

Yea, it's just as much of a pain in the ass for me too. I just hope they don't block SupraMania. I'd be very lost. It's what I do for 12 hours on shift 6 days a week.

That's a nice looking driveshaft.


But, just out of curiousity, is there a huge difference between the aluminum and steel driveshaft? I've read that the steel one vibrates a little more and is also a couple pounds heavier.

Price wise theres a huge difference, and weight wise theres only a two pound dirfference

 

[IJ.]

Depends on who makes it and if they put a damper inside, both will ring without one and of course Aluminium is lighter.

But, what about the noise and vibration. I was reading on the description on the Suprasport website that the aluminum greatly reduces the noise compared to the steel one. What's the price of the steel one from Jawsgear?


Sorry about all the questions everyone, this is just a big purchase and I don't want to regret anything.

 

[IJ.]

Like I said if it's built with a damper inside (usually a cardboard tube) it should be fairly quiet, if not you have a BIG LONG echo chamber

Drop Jeff at JawsGear a PM and ask for pricing.

I already PM'd him about the aluminum one, I'll wait for his reply to ask him about the steel one. Thanks IJ.

My car came with a 1pce aluminum shaft. The previous owner seemed convinced that he felt a "kick in the pants" when that upgrade was done. I don't notice any unusual noise or vibration, but when you shock the drivetrain's natural slack it does make a hollow ping sound, like a big hollow tube would make.

I have had a JAWS DS for ~3 years.

I noticed:
-better shifting
-less drivetrain noise/ slack
-smoother accel

I also had:
-more rear end noise
-a ringing/resonation (but no vibration)

I think my observations are common for a number of reasons:
1. OE center bearing was shot. lots of vibration, slack because the DS was moving in a loop, not a flat plane.
2. my rear end was on its way out. I pulled the drain plug and the magnet was missing....I swapped to a new rear (10K old) and the noise went away
3. The resonation was either something in the tranny or the beginning of RK. I could never duplicate at rest (incase it was the engine). I packed the nose of the imput shaft with grease (as a temp isolater) and the ringing was gone for a few miles (until the grease pushed out). I haven't been able to test out my Rk idea yet, as both the motor and tranny are being rebuilt. I'll report back when I get things back together.

Do you have steel or aluminum?
