Options for Reducing Torque Twist

[littlebuddha]

Hi, I know there have been some threads on this but nothing really definitive on what really works and what does not. So far the options I have seen are:

1) RURLS - rear link location
2) GCM Rear Axle Truss (not sure if this helps or not)
3) Custom Rear Sway Bars (not wild about this option - would be great if someone had a direct fit kit).
4) Shock spring/oil adjustment or upgraded vaterra/proline shocks

Is there anything that I'm missing? any options work better than the other? I'm thinking of giving the RURLs a try since its the cheapest option.

I have installed the RURLS and the Vaterra aluminum shocks. I see no improvement in torque twist as a result.

Moving the shocks further out on the axles is an option as well. This is fairly effective for a (almost) free mod.

I had the same observation on the RULRs, did not provide any noticeable reduction in TT.

Yeah, I didn't see much if any at all noticeable benefits with the RULRs. In fact, mine are disconnected now, still just attached to the frame but when I installed MIPs the RULRs didn't fit anymore.

If your not going to use your stock battery/rockslider mount, you can save some money by swapping them from left to right and use the battery tray mounts for you rear lower link mounts. Won't cost you a thing!!!!!
The sway bar would be your best bang for the $$$ to combat TT.

Thanks guys for the helpful insights - so looks like I can cross out the RURLs. What do you mean by moving the shocks further out? any thread with some pics of this done?

Thanks - looks interesting - any thread with the pics of this done? I was thikning of the swaybars but would be good if vaterra or someone made a direct fit option. As far as I have read - you have to retrofit an axial one.

follow the link and go to post#9, you will see 3 links to 3 different builds using the Axial swaybar kit

Moving the lower mounting point of the shocks further out towards the ends of the axles. The further out you push it, the more TT reduction that results. I'm sure there is a limit to how far out the shocks can be moved before performance suffers but have not tested to find where that limit is.

This pic gives the basic idea:

I haven't tried this method...yet...it's free to almost free though, all you need is longer screws for shock mounts, spacers and washers.

Thanks this makes sense. Will give this a shot for sure. btw have you seen the GCM laydown rear suspension conversion? They say it's to provide space for bodies with low beds but I wonder if it will have a similar impact on the torque twist.

I am well aware of the GCM kit, it has been on my truck for a few months now.

The kit by itself does nothing for torque twist. However, when combined with stiffer rear shocks, TT has reduced considerably with no impact in performance. I have detailed the process in my Ascender thread.

Hope this helps.

On the beater i did rulr and 45w in unmodded rear shock it helped alot but i am going to put a sway bar kit on it the flex u lose is almost unuse able anyways imo. The biggest improvement i have seen is a nice firm rear end mmmmmm

LIFE IS GOOD

[lel-95]

I run the RULR, Wraith sway bar and lowered shocks and I get very very little twist. The Ascender has tons of flex so losing a little from the rear is more of a benefit than a problem, lowering the shocks 10mm and lowering the body has made it into a very stable rig also.

[NickDanger]

I put a set of Icons on my SCX based ToyZuki rig, so I'm going to try the stock SCX10 shocks I had from that and maybe put a little bit longer mounts on the bottom and see how those work with the Ascender. They'll be shorter then the stock shocks and I'm a big fan of the SCX shocks.

I would assume bring the axle up a little bit with shorter shocks, therefore leveling out suspension links a bit could help with TT, correct? Or is my geometry off here?

[Jeepiac]

I'm very new to the Ascender world, so new that mine is still in tiny little bags in a big box. With that said, I got to drive around an Ascender that was completely stock except for one cheap upgrade, and it didn't have any torque twist. I ran it threw all kinds of rough spots, and the owner competed with in in C2, and did pretty good considering he took it out of the box, worked on it for 5 minutes and entered it. IMO this is a good 23 bucks spent.

What is that contraption? How does it fit and what hooks to it? I don't do Facebook so in any look it up.
