Series 2 ront shock absorber question

[Bill]

Good morning guys. What is the perch-to-perch dimension for a series 2 front shock when the shock is fully extended?

[EdWills]

Hi Bill.

Please check https://anglocanadianlotus7.ca.  There are some measurements posted there that may be of assistance. @SENC sent me some original Armstrong data regarding Series 2 springs and dampers a few years ago that is also very helpful.  Perhaps he or I can send that to you also? W.

If you have not got an answer by tomorrow, would my picking up the front end of my Series two and taking some measurements help? I've got the original springs/shocks.

I think those resources are here in the library.  If you can't find what you need there I'll look through my files.

Hello Henry.  I have just checked the library and your file is there, apologies for not checking before..  I have just measured an old set from a Lotus Seven Series 3 (same as later Series 2 cars), and the measurement, with spring, from perch to perch is as noted in your file - 9 inches.  The measurement from the centre of the top mount to the centre of the bottom mount on my set is 12-3/4 inches plus or minus (one was 12-5/8", the other 12-3/4").  Some of the springs supplied to Lotus to mount on the Armstrong dampers were known to sag (according to Lotus). Trust this helps @Bill  W

Thanks guys! I’m always amazed at the collective knowledge this group has! It looks like I have the correct front shock absorbers.
 

Next question: what is a good source for springs?
