So, I've read through pages of old threads on past efforts to come up with a limited slip unit for the standard J-H rear axle. However, I'm very interested in adding a limited slip to my J-H project car, and can't use a non-standard axle like the Firenza, Toyota, or Mazda RX-7 to get one. So, I stopped by Gripper Differentials in Coventry, UK today. While there, I handed them a spare J-H differential carrier to use for measurements and possibly design & production of a limited slip unit for the J-H. They're hopeful a suitable design can be developed that avoids expensive custom tooling. There are currently two of us interested in a unit. If anyone else is interested, drop me a message, as more units will reduce the per unit price. Not a lot more details for now. Note - it may be a few weeks before we know the feasibility & cost. -Steve p.s. Gripper had a Vauxhall Firenza competition limited slip sitting on the shelf. If only my race rules allowed running the larger differential housing required for this diff... Last edited on 11-26-2015 09:27 pm by stevegarnjobst |

I might be interested, but it naturally depends a bit on cost. Please inform if you get a ballpark figure and price profile vs units ordered. -- Joachim |

Good news! I just received word from John at Gripper, indicating a limited slip design has been completed, and production of 5 units is underway. Other than my one unit, I believe Lotusbits is acquiring the others. Anyone with serious interest should contact Gripper or Lotusbits ASAP. Note - I don't have a vested interest in this project, other than the one unit for my vehicle - I'm just passing this information on as a service to the J-H community. -Steve Contact info: Gripper LSD John McMahon tel: +44 024 7668 3239 email: sales@gripperlsd.com Lotusbits Mike Taylor tel: +44 019 2663 3211 Email: lotusbits@hotmail.com |

The other unit mentioned by Steve is going into my JH which already runs an engine by Lotusbits. Cost point right now seems to settle in at app GBP 1.100,- per unit without WAT or any applicable import tax. So there's still 3 units from this production run to go around... I for one look forward to what it does to the handling on the track. Kim |

Very probably! I left it with Mike a few weeks ago to let him have a go at the long standing issue with the LSD. He called me today and said they found a solution and that someone from the US would pick up one of the remaining units - I suppose that would be you! By the way - thank you!
