I have ~93K miles on the car, ~1200 on the new motor, about ~2000 on the trans. Last time at the track it ran 11.47 @ 119.96, I think its time to replace the u-joints. Who sells the larger ones (still using the stock drive shaft)?
I agree with Tony. I paid around $300 bucks for a steel 3.5" shaft. You have to invest in a good drive shaft because it will fvck up your car and maybe you if it breaks.
I have the HD 1350 joints. No issues.....
Spicer makes a 1350 slip yoke 3-3-4281X to fit 200r4/350/700r4...27 spline ,$60 approx.If you can't find local ,I have it in stock.1350 Diff yoke was a Gm produced part for a 8.5 PU, but I don't have a part number.I'm sure aftermarket has it available in $100 range.$200 will build 3.5" .083 wall steel shaft balanced plus $20 each for GOOD u joints.Good investment for strong car
Digging up old threads...
The Spicer 3-3-4281X will NOT work in our cars, the snout that goes into the trans is 4.5", The factory 3R GN slip yoke is 3 5/8ths. I have a 3-3-4281X I can't use if someone wants to buy it.
