Sorry Carter, we can't edit a post in a Group Buy thread - update to the below for posterity

For comparison, the SuperNow kit is comprised of NMB Minebea pieces:
- MBWT14 bearings throughout
- HRT16E NMB NOE200 rod ends - two trailing arm, two toe link
- HRT16E NMB NOE200 HRTL16E NMB N4E150 rod ends - two toe link


Disregard the Kevin Doe note - he took on a similar awesome project, but it doesn't fully translate over to what you're doing here

Thanks for the information on the bearings. NMB are great bearings also.

The OEM trialing arm bolt is longer than the one I use. As the OEM trailing arm has a counter bore before the threads start to engage. The thread engagement on the ARP is at .75" which is about all the thread you get in the weld bung that it screws up into. I will measure a OEM one thiis weekend to compare though, good thought.


I have seen Kevins A arm bushings, very good idea.

These threads are great to work out the details and see what everyone is interested in. So let me know what you all think that is holding you back from this great idea for a production product. I am assuming price so I can do some searching on sourcing the part differently and see what I can do. I did get some breaks on parts for my trialing arms and have updated the prices.

*pricing with Auroa PNB-10T, PNB-12T sherical bearings:

$580- Front Lower Control Arm Set of 4.
$540- Rear Upper Control Arm (inner) set of 4.
$290- Rear Upper Control Arm Shock Mount set of 2.
$290- Rear Lower Control Arm (Inner) set of 2.

Total for all is $1700.

Extra parts no minimum for GB with sherical bearing purchase.

*below parts have Aurora AURAM-10T rod ends:

Chromoly rear trailing arm GB price $250 set of 2, normal price $295
Chromoly rear tow links GB price $375 set of 2, normal price $425 update TBD on price
