Bolt sizes for Shocks and wishbone bushes?
alistairolsen - 16/11/09 at 08:27 AM

What size are the bolts in the bushes on coilovers? Are the standardised at M12, or 1/2 inch, or utterly dependent on manufacturer?

Also, Im looking at these:

Which I assume will be 1/2" being replacements for some long extinct rubber bush?

Cheers

All the ones i have come across are 1/2 inch.

Hi

There is no standard. All the damper manufacturers supply what you need. But the common sizes used are 7/16" unf - 1/2" unf - 12mm metric.

Although for some reason many kit manufacturers still seem to think it's OK to supply 1/2" unf bushed dampers and supply 12mm bolts for securing them. So be double check if ordering from a Kit manufacturer.

Got my shocks from Dampertech - Dave was very helpful and the service is quick and reliable.

The shocks came with 1/2" eyes, but he supplied me with sleeves to suit for 10mm bolts. Highly recommend the company.

My advice is to speak to him on the phone as I tried asking questions via email but it's much easier on the phone, he was very clear and helped me understand what I needed and my options.

So if I drill all the brackets to 12mm and fit the captive nuts for the top shock brackets then Ill definitely be able to order dampers to suit?

The set I recieved were 12mm bore, cnc stainless steel tube and complient poly bushes not the rock hard items usually supplied. The only problem is that the cnc tube is 46mm wide not the usual 44mm needed to fit standard brackets. Not a problem for me but maybe for others

**Correction the bore is 1/2" on these rally design bush sets, getting mixed up with some 3GE components bush sets**
