Changing the stock TRX-4 shocks

[mash914]

Based on your pictures with the body on, it looks like the springs are almost fully compressed - is that right? If yes, I'd say you're probably going to want to get some stiffer springs (0.61 might be enough).


Once that's done, if you want the body to sit lower seems like you have a couple of options

1. Shorter shocks
2. Reposition where the shocks attach
3. Lower the body on the frame

In your shoes, I'd work to get the body lower on the chassis so you can keep the skid up a bit higher.

If that's not possible you could move the top of the shock mounting point higher (maybe something like this https://www.amazon.com/Aluminum-Front-Shock-Bracket-TRAXXAS/dp/B07F3WCL3Q)
This would allow you to retain most, if not all of your wheel travel.

If you're going to run a body that heavy, you need to find a swaybar kit that you can adapt to fit the TRX-4 frame.

From what I've experienced with the (stock 2lb) Defender body a sway bar isn't really necessary. When I punch it on flat pavement this rig will do a wheelie raising both the left and right sides of the front end in unison. This is due to the reduction in the portals and to me demonstrates the lack of any substantial torque twist.

I ordered some stiffer springs, the blue ones, 0.61 I think. Until they show up, I'll think of a way to lower the body by moving the mounting magnets. Maybe I'll be able to shave off some mm from that as well.
