Thank you - now i got it. :-)
1 inch is 25,4 mm

I found this ( stock-replacement ) U-bolts here:

http://www.summitracing.com/parts/SLF-10484/

U-Bolt Diameter 9/16 in. = 14,29mm ( if i am right )
U-Bolt Length (in) 11.000 in. = 279,4 mm
U-Bolt Width (in) 2.500 in. = 63,5 mm

... will check it tomorrow.


by the way:
Do i need longer shocks or is it recommended to add longer (nitro) shocks?
2" spacer for the front axle are waiting for installation, too :-)

 

If you need shocks anyway then it would be a good idea to get shocks designed for a 2" lift. If not then should be fine to run the ones you have unless you flex the suspension all the time.

 

thx@sheriff420,

i will open a new thread about the choice of the recommended shocks.
