Actual on a factory car you need to shorten the drive shaft most of the time....so extending the trailing arms MAY make the factory drive shaft work better.

There are NO rules of thumb....suspensions work differently from a g-body to a caddy to a X-frame impala to a 65-newer impala, etc.

And Klownin63....extending the lower trailing arms will not really allow a higher lock up....you primarily get a higher lock up from extending the top arms. Extending the lower arms will keep your wheel base longer as you lock the back up.

So how much do you suggest shortening the driveshaft and or extending the trailing arms if I wanted to run 16" cylinders on a regal?

Personally I would not extend the bottom arms. I would extend the top by about an inch and a half and drop the top mounting points on the frame down about 3 inches. Then I would get a slipped driveshaft.

Does Hi Caliber do slipped driveshafts?

It is always a rule of thumb to extend the driveshaft when you extend the trailing arms.

YEAH RIGHT!!!!!!!!!!!!!!!!!!!!! :uh: :uh: :uh: :uh: :uh: :uh: :uh: :uh:

you have no idea what you're talking about...

a rule of thumb (if there ever was one) is to allways move the trailingarm framemounts equally long foward on the frame as you get the trailingarms extended...

I've got a 83 lac with 16 's in the rear and i want a slip driveshaft. Anyone know where i can get one.  Also,what is the actuall function and purpase of a slip shaft. :dunno:
hit up RICH on here for driveshafts.

the use with slipshafts is that when you lock a car up in the back the rearend gets pulled fowards cuz the angle of the trailingarms gets worse. so then your driveshaft will fuck up the tranny or carrierbearing or both, a slipshaft has a bit of splincetravel that allows it to become shorter-longer so it follows the rearend's travel foward/backward.
