CRT.5 Big Bore Shocks done easy & cheap

[miniGranis]

Thanks for the clarification.

I have some updates to the upper mounting system for the Revo shocks. I found that with the Ofna part 36610 the shock cap was hitting this part and not allowing the shock to swing backwards in the event of a broken A-arm. Because of this I bent a shock shaft. Granted the whole front left side of the car was destroyed (a-arm, knuckle, c-hub, ball cap, shock shaft) so bending a shock shaft on that hard of an impact may not be avoidable.

So, I've removed part 36610 and replaced it with the original crt.5 upper shock mount. However, I did not remove the Revo pivot ball. So I'm just using the crt.5 shock mount as a spacer. This moves the shock even farther from the shock tower and allows the shock to pivot rearward in the event of a broken a-arm.

Now to mount the upper shock all you need to add is (2) 35mm screws and (2) washers and lock nuts for behind the body mount. The other parts are stock.

Jammin X1CR front shocks do fit pretty much perfectly on the rear of the .5. Mine are set up with a good oil, but the soft springs I have on them right now seem a bit stiff. Once I mount the Jato shocks like you did I can dial in the suspension.

Nice work!

I gather that the softer the better (for the rear). I have a set of mugen soft/short light blue springs on the way as well as the x1 cr front shocks (for the rear), and of course the revo shocks and accesories for the front. I hope the mugen springs are soft enough without cutting them down. I'm stoked to see the improvement. Go-ride well done on the mod.

I just ordered a set of Ofna Ultra LX One front shocks (same part #s as the 13mm X1 CR shocks) off ebay yesterday. They come with the soft "yellow" ofna springs. Hopefully, the yellow springs will be close.

What springs are you running on the ofna front buggy shocks?

On the front with the Jato pink 1.4 springs I'm pretty much have max preload, which really isn't much because the Revo shocks are not threaded very far. I was thinking of going up to the 1.6 springs. How are the green 1.1 springs setting up?

One other thing I noticed is that if you tighten the bottom cap tight on the revo shocks it creates a lot of drag btwn the shock shaft and seal. I'm thinking of puting a small oring or thin nylon washer btwn the cap and shock body so the cap stays tight but doesn't over preload the seal.

I am actually running jato shocks which have more threads than the revo shocks.With not much preload set, my ride height is dogbones pretty much level, maybe just above. I am also running the bottom caps that come with the shock dust boots, which are a slightly different design to allow use of the dust boot; I have not noticed any drag.

I am running THESE as rear shocks. I think I using the springs that come with them, but the springs I am using I just found in my box of shock parts. It makes the ride height arms just above level.

Bye

Ahh...that explains a couple of things.
1. I bet the shock caps I have are the same as the ones for the boots, but without the boots (I don't have) they over preload the seals and create drag. The only way to notice the drag is to back off the cap a bit an see if the shock moves more freely. I have now installed an o-ring under each cap to reduce the preload on the seal.
2. It's too bad the aluminum shock bodies don't come threaded as far down the body as the plastic Jato bodies. I might just flip my preload caps over to get more preload.

hey fellas,
just wanted to say that this has been a great read. Thanks for the info. I haven't tried this yet, but I like the concept. Keep it coming.

Much better cost then the full ofna set up! I wish I still had my .5 =( I never thought of using the body mount holes!

How ever, does anyone need some revo shocks for cheap? I have 4 of them, 2 of them have ti-ni shafts, and the other 2 are normal, I cant find the other package of ti ni shafts lol.... PM if any one is interested

Even cheaper then revo shocks! With more threads too! Also a bit lighter because of the plastic body....

Bye

If any of you guys need the revo stock shock just PM me. I have sets of 4 that I dont really need. I'll let them go for very cheap price. They are in excellent condition.

That's exactly what I'm running

Bought those Jato shocks last night with the 1.4 rate springs. Hopefully it turns out well. I'll post pictures once they're installed.

Just got done setting up my shocks for how I like them - although I have yet to run the truck with this setup. The front Jato shocks have 1.4mm pistons, 40wt. Losi oil, and the Traxxas 1.4 rate pink springs. In the rear are Jammin X1CR front buggy shocks with 35-40wt. oil (I forget which) and XTM blue (soft) front buggy springs. Pics of the whole setup:






The way it sits is just slightly above level, but it should work fine, I think. The rear shocks bottom out just as the back end of the chassis touches the ground, and the front shocks still have about 2mm of travel left when the front end bottoms out.

Looks great. I should have my ofna big bore shocks for the rear this week. They are coming with ofna soft (yellow) buggy springs. I'll let you know if I can get the rear bones level with these springs.

Here are some pictures with the new Jato shocks. Does nayoen knwo where I can get stiffer springs for the back of the CRT.5? I have the stock silver ones, and I just need something stiffer...






And don't yell at me for not using Mike's mount. I got this one for free so I will run it until it breaks or something happens to it. And then I'll buy Mike's mount.
