Sorry, it does read that way but the 4-speed axle is much lighter and one of the reasons why the 4-speed TR7 can feel a bit more sporty.

I have a 4-speed TR7 and a 5-speed TR7 and had the pleasure of replacing both axles over the years (also taken off/on a 4HA axle on a TR7 rally car and that was even heavier!).

Thanks for the info. I have a 5 speed axle and gearbox ready to use (after a check and refurb) when i get started on mechanicals.  I like to know all that i can when modifying things.  The internet is great at giving so much advice then someone throws up a curve ball.

Looks like the parts list is going to get longer!!

Folks

 

i have a 5 speed axle and gearbox plus prop etc that needs a new home.

 

I’ll also be selling my early FHC.

 

let me know if you’re interested before I need to put it all on eBay.

 

regards
