Traxxas TRX4 RC Crawler Treal Shock Tower Upgrade [Install, Test, Review]

This really made a difference to our Traxxas TRX4!
Installed the Treal front and rear shock towers, plus some shock keys to really give some adjustment to the upper shock mounting. So many options!
By laying the shock inward both front and rear, the truck ride height reduced by around 1/4-1/2 inch, plus kept or increased our articulation / flex! A worthwhile upgrade for sure!
How does it crawl with this change? Check out the running footage at the end to see!

Treal has been making a push on to the scene lately. They're doing some sharp parts for sure

[@RoadsideRC]

Agree! I am very happy with these parts.

[@BlackSmithRC]

And that's how you tune your rig! Shock positioning is most important, you nailed it bro! But I think you still have one more position that will assist in performance. Move the top position one space toward the rear. Should find a whole new feel of "balance". M.I.D.W.I.D!

[@RoadsideRC]

Awesome! Will try that - thanks!

[@alestbest]

You are my hero. Thank you. Lower, thats what I was looking for.

[@RoadsideRC]

Great! Glad it was helpful!

[@TrillMurray]

If you don't think 10mm will make a difference on a 1/10 truck, consider that it would be equal to a 10 cm change on a full size truck, which is significant

[@RoadsideRC]

Good point!!

[@TrillMurray]

@@RoadsideRC it's a fun way to put the scale in perspective! I like to visualize the full scale equivalent when I'm working on the rc car and vice versa. I think 1/10 is a really fun scale for that reason.

[@sprather84]

Awesome my friend I'm definitely going to look into these one of the things I've been wanting to do 👍💯 Something that made a huge difference in my performance was getting rid of all the preload on the shocks and running them in a droop setup huge difference with that

[@RoadsideRC]

Great! Thank you for that! I actually changed some of the settings as I did this change.

[@andrewfeinstein1110]

Now you need some 200mm shocks. I tried it on my crawler and it gives the flex way more angle. I have basicity the same setup on my trx4.

[@RoadsideRC]

Glad you like them - but I am not a fan of too much flex. In my area, it just makes for an unstable truck.

[@chpf0324]

Great tipps, many thanks! Thats the best way to make the suspension longer. Unfortunately the parts are no more orderable. I found similar but not so good ones on wish...did not recieve them yet, but looking forward to get them.

Awesome video Troy, love the upgrades, it’s gonna bottom out a lot more now. It looks great! Literally the only thing that bothers me on my K5 trx4 is that the body rubs on the tires, and I can’t seem to find any fender accessories☹️ What servo is on yours because I wanna upgrade mine as the ONLY upgrade on mine is the esc

[@RoadsideRC]

It has one of the ZOSKAY 25kg servos in it now, but I really like their 35kg. So far, the bottoming out is really not a problem...but it drives a lot better.

[@ryanwalter757]

A lot of people don't realize this but if you turn the shock key's upside down you can actually make them into a adjustable body mounts so if you wanted to fit a short wheelbase or a long wheelbase JK body to a d90 or d110 chassis it will actually work with that as long as you have the right size threaded rods

[@RoadsideRC]

Nice tip!

[@covecityboys]

Put overdrive gears in the front and underdrive in the rear and you’ll walk right up that impossible wall.

[@RoadsideRC]

Getting the truck lower helps a lot!

[@0000oooopppp]

@@RoadsideRC I totally agree. In fact I loved the video and the Trx performance is awesome. I was thinking on the added weight at the top of the car. How it could probably affect the sidehilling. But yeah lowering the rig helps it overall.

@@RoadsideRC dang too bad they were sold out ! I ordered rock pirate shock towers instead excited to see how they work 😀

[@bapasrcadventures3619]

Did the shock keys cause the top of the shock to be angled out at the top? Because of the thickness of the shock key? If so is that ok to do to the shocks? Thanks again

[@RoadsideRC]

Very slightly, yes. It has no ill effect on the shocks- they are fine.

[@braddunn5983]

Do you know if the keys will work with factory shock mounts and give me a good amount of adjustment to play around with or will I have to buy the treal mounts to use keys in many different positions?

@@RoadsideRC dude amazing

[@blowback8852]

What will be the benefit of the rear shock being angled forward? Any disadvantage?

[@RoadsideRC]

It is the same as the front shock being angled back. The more angle (in the same direction as the control arms) increases flex and reduces ride height. If this effect is too exaggerated, it will reduce side-hill stability.

[@blowback8852]

@@RoadsideRC but if angled at the right settings, will it help in side hilling? What about in climbs sir?

[@mulerc3875]

What rear body mount is that? I noticed you lived the rear shock tower forward a few “

The rear body mount is the stock Sport mount, and I think the shock tower is in the stock sport location. Do you have a Bronco/Defender model?

How do you figure out what angle your keys goes an how do you know that’s gonna make sense am benefits your crawler, that’s what I’m looking for in this video I can’t seem to find a super informative one but that I feel like that’s another category or to details to go into, anyone?

[@RoadsideRC]

My goal for doing this, is to lower the truck for better CoG, while still maintaining the same amount of flex, or perhaps even gaining some. You will notice I angled both the front and rear shocks inward more. Then, I tried various angles to change the ride height. When the key was angled up, I had basically lost all suspension travel, so moved them more downwards to increase the ride height. Does that help?

Idk man... This doesn't look too strong to me... You loose a shear point for the shock making it's connection much weaker as well as adding so much leverage by sticking it so far out from the shock tower that a fall or hard bump could bend it... Unless that screw holding the shock with it's now single shear point were to actually shear off... Idk. Maybe for you and the driving you do this works great. Hopefully it does. I just don't see it being stronger in any way...
