6.7L Cummins Owners: Why You Should Consider a 4 Speed Swap

Posted on 20 August 2015

If you need to go fast at the track and want full control of tuning, a 4 speed swap is what you need.  Gone are the over-complex factory computers, limitations and drawbacks.  Whether you choose a 47RE or 4R100 swap, the result is complete tunability, quicker shifts, faster E.T.'s and better reliability at higher power levels.  

Street Diesel Power has made ordering a 47RE or 4R100 swap kit easy.  Simply select "yes" and "no" to various options on our build sheet and we handle the rest!  If you have questions about what billet shafts to select, lead times and installation - give us a call or send us an email!
