No real chance to get a new shock out of the UK before the next Friday given the Easter Monday holidays. i had a pair of old front shocks but did not want to use them as the spring platforms were not adjustable and the springs rates less than I wanted to use. So I decided to make up a new stud and reweld it to the shock bottom eye.
I used a suitable forged high tensile bolt and machined it to the correct profile and cut a thread for the new smaller diameter threaded section, handy to have a lathe when you need it for urgent jobs like this. I also made the stud a few mm longer as the standard TTR shock stud is a little short and you have to over compress the roll bar securing rubbers to get the nuts fitted on the threaded section fully. The stud had failed due to a fatigue crack around where the head of the stud thats welded to the shock had been machined with a sharp radius. Hopefully using the bolt with its forged head it will be less susceptible to this problem. Got a friend to weld it to the shock as it would take me a week of practice to do a top quality small fillet weld that's needed to secure the stud head to the shock eye.
It should be OK now and hopefully better than original but I will order some new shocks as the other one is probably due to fail soon and i have wanted an excuse to experiment with some different spring rates . The current TTR shocks and springs have lasted more than 10 years of regular racing so I cant really complain.

I'm interested to know how well the roll bar fits? Late last year I set my suspension and was really pleased how well the roll bar fitted - bolted to chassis mounts and offered the ends up to the shocks and it fitted absolutely perfectly - normally I'm thoroughly pissed off that nothing fits and the roll bar is one thing I expected to be slightly out and so causing a side load on the shock.
How good was it?
