Can anyone here share the exact lenght of the Supershafty /JEC Racing trailing arms and links for both bomber and Wraith?

I just received my second set from JEC and they seem like bomber lenght again instead of Wraith...

I want to measure the links as well before I dismantle the bomber for nothing.

Maybe my traxxas rod ends are not screwed in enough?

When I get home I will try to remember to measure my Bomber SuperShafty JEC arms without the rod-ends. I know that JEC shortened the arms by a couple of mm to help with the pinion angle over stock.
 
Can you measure the arm only without rod ends?

Wraith - 115.25mm
Twin Hammers - 102.4mm

I will say that in the pic you posted of yours, the rod end on the right could probably be threaded in further. As I recall, the Bomber length JEC/SS trailing arms are a few mm shorter that stock to correct the pinion angle a little. I think this is what you have pictured.

I'll also add that switching to Wraith length put my wheelbase at about 14.25".
 
Well damn, they are 115mm
I guess my rod ends need to go in a few more turns.

When I hold the next to the stock arms I swear they look almost identical.

Metal portion from end to end is exactly 121mm on the Bomber length - you should ignore the rod ends I used, as I had to use Jato ends on one end, and Revo ends on the other to get everything worked out with the wacky setup I'm running... I'm using front lower arms as rear upper arms and my total lower arm length is 147mm from center of ball to center of ball :

I had a hell of a time getting the Revo ends into the JEC arms. I always bury the grub screw into the plastic then install into the link. The JECs are too tight to do this. With the grub screw burried into the Revo end it swells too much to fit properly into the link. You need to bury the grub screw into the link then install the rod end. Then it will fully install and will be the right length.
