Selling my S4 that was built by Kevin McMullen racing /transaxles
Trans was originally built inJanuary of 2020 when the shift housing and all outdated parts were updated . I ran it for the season then in January of 2021 the main case developed a hairline crack It was sent back to McMullen for a new main case and freshen anything (if needed )
I received it back July of 2021 .
I put the trans back in the car for 1 trip to Idaho while waiting for my new s4d to arrive . Trans was broken in exactly as directed my mucmullen .
New s4d arrived last week so this one is for sale
I have all the paperwork and build sheets from McMullen. Trans is basically brand new .
I will include the adapter plate and 9” twin disc Kennedy clutch pressure plate and flywheel all were new 1 season ago
Price does not include shipping buyer to arrange their own shipping or pickup . Usually cost about $ 300.00 for me to ship from Northern California to Phoenix .
Ring / pinion 4.63
First 2.91
2nd 2.14
3rd 1.67
Asking $12,000 OBO please call or text with any questions
