pcwesthead Posted September 22, 2021 Report Share Posted September 22, 2021 Hello all, I read that the ride height measured at the sill should be 6 inches for a TR3a. Mine was lower than this at about 4.5 inches. I was changing the bushes anyway, so decided to replace the springs with Heritage standard springs. Having done these jobs, the ride height is about the same, 4.5 to 5 inches. Didn’t see any spacers on the car or in the Haynes manual. Is that height wrong? Any insights would be appreciated.

BlueTR3A-5EKT Posted September 22, 2021 Report Share Posted September 22, 2021 (edited) Just measured mine. My tyres and wheels are standard 165/80x15 on TR6 5.5 wide rims. 6“ bottom of outer sill to floor at the rear wing to quarter panel stone guard. 7” bottom of front wing lower edge to floor. My car has Regular rear leaf springs and Triumph Tune tall updated front coil springs. I chose to raise the front of the car to stop the chassis being smashed by the lumps of tarmac the local council have added to the roads.

Do you have the correct rear shackles fitted? The solid axle 4a ones are longer. Stuart. Quote Link to post Share on other sites
pcwesthead Posted September 23, 2021 Author Report Share Posted September 23, 2021 Thanks Peter and Stuart. I found the old thread on this so looking at that also. My shackles measure 2.5 inches between pins. Which i believe is correct. Quote Link to post Share on other sites
