LT1-LT4 Modifications - Is swapping ls1 driveshaft a direct replace
05-03-2012, 06:00 PM
Trying to see if I need anything to swap a ls1 driveshaft in an lt1 car

If you like a weaker-than-stock replacement it sure will work. :)

If its weaker than stock why do people do the swap? Is it because the LS1 driveshaft is better balanced then the LT1?

Aluminum LS1 driveshaft is a bit lighter than the stock LT1 steel.

Lighter for one

I thought maybe the yoke was different

I dont think there differnt, from what I have heard just a good idea to change while you change the driveshaft. Lighter so it spins faster, but if your putting down power the lt1 would be better option

LS1 is weak, but for stock and daily driver applications works fine, also is a little smoother at higher rpms

I just put one in my car plug and play.

Its a direct swap between the two shafts. LS1 ds is lighter and a little smoother at high speeds, but the steel LT1 is stronger.
Make sure you have the aluminum shaft under the car with you and ready when you pull the steel one out of the tranny, as some tranny fluid might spill out depending on how forward the car is tipped on the jack stands.
