are you still making these mate

Any progress mcgee on the traction rods.

i was hopeing you would have these sorted soon as im waiting for them to run my car on the track

Do you think you will have any ready before you head south?

OK update,
Have the rods now and am awaiting a Quote for the CNC lathe work.
The rods will have 7/8" hex flat machined into one end to allow on car adjustment.
Have made some test Delrin spacers and spring roller made so can check clearances this weekend.
I need to have the CNC lathe work done prior to getting all the parts zinc plated.
I have a bit of a compressed timeframe now as I am moving from QLD to NSW in three weeks.
Non the less I think the wait will be worth it.

Next update will be when the lathe work is completed.

Regards,

Ok time for an update.
The tube supplier has been pretty slow but hopefully I should have it this week.
Finally took a closer look at the ute setup today.
To attach the kits to the utes you will have to drill out the inner front spring mount hole, in the chassis rail, to accept a 12mm bolt. The stud on the utes has a step down from 12mm to 10mm at the chassis rail, there is no way around this unfortunately. If you were to remove the traction rods at a later stage you would just replace the bolt with a 12mm 90mm long grade 8 bolt so no real big issue.

Attached are a couple of photos of how it will sit on the ute.

This pic shows the step down in the stud, the chassis rail will need to be drilled out to 12mm to accept a 12mm bolt right through. The stud is easily tapped out of the outer mount.



This pic shows the plate and bush mounted on the plate, note that the two outer bolts stop the plate from turning hence the change required in the design of the triangular plates.



Showing the triangular plate and bush on the outside of an original coupe/sedan/120y front spring hanger, it would be possible to do this will normal eyed springs (Reverse eyed springs will not work this way).



Another angle showing the above setup.

After some searching I have sourced some rod ends with a 3/4 UNF with a 5/8 rod eye, these are Teflon lined at a reasonable price. So am looking at going back to a 3/4 UNF L/R thread in each end of the rod (No plug reducing to 1/2 UNF thread).

Will keep you posted when the next round of parts arrives.

im keen for 4 sets when they are done, 3 coupe and one ute! :)

Hi guys,
Quick update. I have sourced the 4130 tube and should have it in my hands on Saturday.
I had a small issue that I needed to overcome but hopefully I have a solution.
The issues is with the 50mm width of the 1200 spring and the bushed rod ends. The bushed rod ends are 1 1/4" wide ~= 32mm so add two 5mm plates to that and you are up around the 42mm wide plus welding filet, this would encroach on the u-bolt nuts.

My version 1 setup used a solid bearing rod end which is only ~ 16mm wide so with the 5mm plates that makes 26mm leaving 24mm for the filet weld and u-bolt nuts, not a problem. Also it was almost impossible to find a 3/4" UNF to 1/2" hole rod end at a reasonable price (these were over $100 each).

So the kits will now have one solid rod end and one urethane bushed rod end. This means less flex in the kit but I still think it will be better for the street then two solid rod ends. One end of the rod will have a 4130 hex plug in it containing the 1/2" thread for the solid rod end, the hex section will facilitate on car adjustment with a 1" spanner. There will also be a left and right hand jam nut at either end.

The roller that sits on the spring will have a Acetal (Delrin) spacer. Delrin was chosen as it has a low Coefficient of friction and good mechanical properties, these are designed to wear (instead of your leaf spring) so I am happy to throw two sets in with the kit.

Price is still pegged at this point to be approx $400.

Hopefully it is all steam ahead next week, the parts are starting to come together nicely now.

Cheers

Bryan

should be nice and cheap now. mass production.

i will be in for a set for a ute.PM me when you work it out.
