Longer bolts for trailing arm spacer

[Jamie_stafford]

Hello, I'm looking for longer bolts for my trailing arm spacers I have made, I think they are m12 but not sure on the three as it is quite fine, any ideas?

Which model car, Jamie? That might help a bit ... :iconwink:.

NachaLuva can probably tell you exactly what you need.

Oops sorry, it's a 2004 impreza sport wagon

Last time I did a body lify on on a Subaru the trailing arm bolts were high tensile M12 fine pitch. Subarus are generally all built from the same parts bin so the imprezza is probably the same.

Wheel studs are also M12 x 1.25 so if you can fit a wheel nut onto your bolt that will confirm the thread size.

Brilliant thanks for the help!

Make sure you specifically ask for 'high tensile' bolts for that application especially so since because you are installing longer bolts.

Did you make the spacers from a solid block or hollow section steel? If you used hollow steel you need to install crush tubes inside and spring washers on the bolt head inside to keep everything legal and safe.

Just take one to a bolt/engineering supply and ask for some 50mm longer, or personally I'd just pm NachaLuva and buy some off of him.

You'll need M12x1.25p x80mm long for a 2" spacer. Specify grade 8.8 zinc plated
