Due to upgrade I'm selling my 3.9 diff..
It's a 7.5inch LSD with a 3.9:1 ratio which livens up any cossie like you would not believe. (depending on tyre size and rev limit im sure 170+ mph is still possible)
Mileage wise this unit was rebuilt by an ex RED engineer then bought by me, fitted.. Driven to a dyno 40miles away, dyno time then driven back. (I found that my block had cracked so it hasn't been used since then.)
Whoever has this unit will not be disapointed!
It was nice and clean until I got my oily mits all over it

(Mount is not included in sale.)
No whines, bangs or any other faults as you'd expect for the low mileage.
£450 plus post.
Cheers,
Luke.
