Got some second hand shocks to fit to the car whilst I refurb the springs and shocks. I was surprised to see different EKT numbers on the integral bump stops on the rears:



The shocks have the same part number and the TVR stamp in the shock bodies and came from a '98 car. The front shocks have EKT 3 bump stops incidentally. I've searched on here and on t'internet and can't find any reference to them or whether it's significant. I expect they are just slightly different rubber compounds, but perhaps they're is something more here that I should be aware of?

Looks like similar material if nothing else, they also look under used too wink
I'd not worry about it.
I'm using a set of old Koni Shocks originally off a Griff with rather tired bump stops but I don't find I hit them very often or at all. I used to hit them regularly on after market shocks but they had low rate springs fitted at the time.
I really like the softer ride with these Koni, a bit floaty as they are old as the hills so I'll get then refurbed and go with them as I like how they work and dampen thumbup

I replaced the bump stops on mine recently and contacted the Bilstein technical centre; they told me the current Bilstein part no for the stops is the same for both front and back - E4-B46-759.

That's good to know. Part numbers of many car parts remain the same when they 'upgrade' or revise them but retain the same size / use. It's probably just a change in rubber compound. The spare fronts I have must be later spec since they are marked EKT3.

Just seen the other thread on replacing them. Mine don't have a pin so I would just need to wind the ends off to replace them, (without damaging the shaft somehow) so I'm glad they don't need to be!

The other thing I forgot to mention is that one shock has a nut under the eyelet, the other doesn't. Same part number of course. A bit annoying because the spring had to be compressed even more to get the collar off:
