Hi everyone. Just after a measurement from underside of the x member to top of the mounting face. So basically the height of the x member without any control arms.

I'd say 57 members looked at this because the thread title is quite ambiguous?

 

Many of us here are interested in suspension geometry and improving handling, so would have opened the thread just to see what it was about.

 

This may be a silly question but what are you trying to figure out? As far as I know, the dimension you're chasing would be the same across all the big Torana K-members so there isn't really anything to verify?

I'm putting a Commodore front end in my hatch. Want to make sure I'm in the right ballpark for height. So engine will clear the bonnet.

Is that from underside of the x member to top of chassis rail? Or just x member height?

So underside of the chassis rail to bottom of x member 340mm. So height of the x member by itself is 340mm correct?

Underside of cross member to the underside of the chassis rail mount. I put a straight edge across the rail mounts, then measured to the lower side of the x member, x member is from a 1977 UC.

That doesn't sound right?

 

Commodore chassis rails (at least the early ones) were much lower than the Torana so the height of the K-member should be smaller than the Torana, not 100mm taller?

under side of k frame is the flat bit of the k frame that usually gets dinged up from possums and wombats , sometimes rocks and wallabies and it has a witness mark in the center/ish.

the pad on the k frame is where it mates parallel/ish to the front rails  is the bit that is insulated by rubber/or otherwise that go between the pads and front rails , measured from a 77 hatch k frame , but the 77 uc might be a bit different ? typo? :)

Using the ground as a datum is subject to tyre, rim and ride height. Which model variant are you intending to use as a baseline?

Cheers for that.
So i now have 3 heights
575
585
587. All to top of chassis rail at the front bolt hole from the ground.
I also have 3 different heights to the underside of th engine crossmember.
135
150
155.
So mine at 150 and 590 is near to spot on.

Good to know. Thank you.
Atleast I know it's within the std height of the lx and won't look out of place so far so good
