Hey guys,

Just twisted up my Aluminum .125 wall 3" shaft I had built by a local drivetrain company and need to go up to a 3.5". I'm looking to see if anyone has clearance issues with the 3.5" shaft as it looks pretty tight with my 3" exhaust w/ Y pipe.

Thanks

Youll need to move your exhaust. Plain and simple. Yes its tight.

Can you elaborate on what you had to do? Everyone seems to say its a direct bolt in... Just wanna make sure what I'm getting myself into with the work.

Thanks man

I've never had much of a problem with 3" exhaust systems being in the way. A 3.5" driveshaft is only .25 out further towards the exhaust. Bob

i just put a 3.5" in mine. its tight to get it in but there is plenty of clearance.

If your car is lowered watch for DS clearance to the e-brake bracket in the top of the tunnel. Don't ask how I know its tight....

The only issue I ever ran into was always having to undo my short tq arm from the tunnel because of the driveshaft loop, but room wise I don't think it makes much of a difference.

smart thing to do is remove the rear springs, let body rest on the axle via bump stops. measure clearance of drive shaft to everything so you know.
when i put in the S60 rear, my 3" aluminum drive shaft had about 1/16" clearance to that metal piece on the tunnel for the ebrake cables. i ended up cutting some 1/8" steel and use it to shim the bump stops. if you are on rough roads and have people in the back seat, risk is higher the axle will travel upward too much and drive shaft will contact that bracket on the tunnel.

Been running a 3.5" Lingenfelter with 3" exhaust for almost a decade with no issues.

Thanks for the insight everyone. New shaft will be done on Friday and will see how it goes in. I upgraded the pinion yoke to a 1350 in order to run a solid 1350 joint in the back and avoid breaking a conversion one again.
