For racing maybe but not for towing. I would never go back to a four speed anything if I could have a six speed instead.
They are not just for racing. Spoke with the guys over at Revmax when I was looking for an upgraded trans and they said it was a popular swap even for those not racing. There are some on the Cummins forums that have swapped and are not racing either.
Although, this was because for a long time no one was able to build a 68RFE to hold over 600 hp reliably. Even the built units were not lasting long so they went with the 48RE. Now, thanks to things like the Sonnax overdrive hub and Revmax valve bodies, you can build a 68RFE to reliably handle over 800 hp.
You go right ahead.
Stock I will take the six speed any day. I hated the gear spacing in my 47RE. With 4:10's the gap between 3rd and 4th was huge. Seemed like it was either 1,800 RPM in 4th or 2,500 RPM in 3rd. The 48RE is no different.
