HEAVY DUTY DIFF MOUNTS

PostPost by: alan.barker » Wed Dec 04, 2019 3:44 pm

I need to replace the Diff Mounts / Frusta Cones on my Elan Sprint.
I think i will fit the TTR heavy duty standard ones. Looking at a photo of them there is more rubber moulding at the top.
My question is do i need to fit longer Bolts than original.
Thanks

Forgive me for being blunt, but have you tried contacting them and asking directly? As someone that hates talking on the phone I had a question when I was buying my new headers from them a few weeks ago and emailed them and they followed up within 24h. I also emailed them with a different question and again they responded within 24h.

TTR offers two upper diff mounts, heavy duty and extra heavy duty. I bought the former and it is kitted with new bolts, as shown on their web site. I don't know about the extra heavy duty mounts, the web site photo only shows the mounts themselves, not a complete kit. I agree with Ben that contacting TTR directly is your best approach. I have had a similar experience in that they are quick to respond to email enquiries.

Thanks Guys,
i have ordered from TTR and they give a very good service.
It's the first time i have used them in 45 years of tinkering on Twinks.
The products on their web site look good

I have just fitted the diff mounts from TTR and they a perfect.
The old Lotus Frustacones i removed were not broken but i think they had sunk a little.
I measured the total height of the Frustacones and they are about 3 mm higher in the centre where the metal tube is than the TTR mounts.
Which means that the Diff now sits higher and a lot more clearance with the Chassis. The clearance now is about 4mm between bottom of Diff and Chassis Backbone. I also removed the Washer between the Diff Stiffener (elan sprint) and Diff Mount.
I'll see if the vibration on overrun has disappeared :wink: :wink:
