FF Shock Identify and Rebuild (Lola T540)

[r33rob]

The attached photo shows the shocks removed from my restoration project Lola T540. I'm hoping to have them rebuilt. One is stamped 42345191156 180/60. I need to know who the shock manufacturer is, and who can rebuild these shocks.

The car was purchased disassembled. I presume the longer shocks go in the rear. Let me know if that's wrong !

Thanks in advance.

Look like Bilsteins. I think there is a place at Sonoma Raceway that can do them. Drawing a blank on the name.

A bit of web surfing yielded Performance Shock Inc. in Sonoma.

Thanks for the lead.

Please share your findings. I have a similar set on my SV.

You might want to ask this guy what he thinks of their service.

ProParts USA for Koni Shock Rebuilds? (apexspeed.com)

I don’t believe they are the same business.

Those are Bilstein shocks. I used the same shocks on the Zink Z10 and Z16 cars.

Clean them up and stroke them to see if there are any signs of leaks. Also check to see if they have the same load it you depress them say 1 inch.

If they pass the above test run them as is.

Spend you money on something else. You will not find shocks that work better than those shocks on you car.

You can do a lot better with Dynamics bump stops that the ones on those shocks. Those bump stops are probably dead from age now.

I don’t believe they are the same business.

There is more than one shock rebuilder at Sonoma

Years ago I sent my 1970's Bilsteins to Bilstein in San Diego for a rebuild. Don't know if they still do it, but it might be worth asking.

Lastminuteracin, you are correct.
My customer made the mistake of sending his Koni shocks to ProParts USA instead of Proformance Shock, He won't make that mistake again.
