Ever since I did my SAS, I have had some increasingly nasty vibrations coming from the rear driveshaft because only 1.25 inches of the driveshaft stub were in the yoke. This caused a lot of slop in the driveshaft. I made this adapter that goes between the yoke flange and the driveshaft yoke. Four 2" cap bolts hold the spacer to the diff flange, and four 2" grade 8 bolts hold the driveshaft yoke to the diff flange. The spacer is 1.75" long. I was wondering if anyone would be interested in one; if there is even any demand for these. Aluminum is fine for light offroading/daily driving, but a mild steel spacer would be better suited for real offroading. Anyway, thanks!

Here are some pictures of it:

I was looking for one a few months ago and found nothing. I finally had mine lengthened. There has to be some people out there who want them.

 

Just stack some flat washers between the mating surfaces!

 

yeah, i made that spacer because I wanted to avoid the $200.00 price tag to get my riveshaft lengthened.

yes, i like the flat washers idea, and make sure the longer bolts are at least 4 inches, the longer bolt, the stronger it is.

 

would you be able to make them in custom sizes and to the desired bolt pattern? I may be looing for one that just acts as a 0.5" solid aluminium spacer with holes drilled for the driveshaft bolts.

 

That looks good. I think I should go that way with my front driveshaft.

 

I wouldn't advise putting an extension on the front. The front diff is always to one side or the other, this means that your front shaft travels a lot further then your rear shaft which has the diff in the center. Basically if you have issues with your front shaft it should be changed to a longer spline/slip.

 

That all depends on whether you have enough slip in your front driveshaft. If you think you have enough, but the actual overall length of the driveshaft is too short, then a spacer will work. If you don't have enough slip, then a spacer will help with the "compression" of your driveshaft, but will make the "decompression" shorter. I had no issues with the actual amount of slip in my rear driveshaft, I made the spacer so the stub would be farther in the yoke, thus giving my overall driveshaft more support, eliminating the wear on the splines and the nasty deacceleration vibrations.

 

how much would you charge for a steel spacer for a '91 4Runner?
