Amain.com usually has all the crt.5 springs in stock. I used the white (hardest) for bashing and racing with the Revo front shocks and Jato 1.4 springs. However, rather than spending $13 on a set of stiffer springs, I'd buy a pair of Ofna LX One front shocks ($20 or less) on ebay that include the softest 1/8 (yellow) springs and mount hardware. That's a much better investment in a crt.5.

I guess I'll do that instead. So this will fit for sure?

Plus the yellow springs match the rims and wing. lol

A little off topic, but the Traxxas Anaconda front Bandit tires will fit the stock CRT.5 rims correct?

Yep, those are them. To get the amount of droop I wanted I mounted them with the supplied mounts, but in the body mount holes on the rear tower. Much like with the Revo shocks on the front tower. They also come with heavy oil (manual says 80 wt) so you will want to go lower. I'm going to start with 30 or 40 wt.

Yep, looks just like mine. I had to cut 2 coils off each of the yellow springs to get the dogbones level in the back. I tried 25wt oil and it was too light, and I'm now running 30wt in the back and 25wt in the front. I've been thinking about getting the ofna blue springs for the front and cutting them down.

I'm running 40wt in front on the pink springs, and the stock oil and springs in the back. They seem to be perfect, but I still have yet to try the truck out to really know...

Hi guys. I'm about to start this mod, but was wondering if any of you guys had some extra Jato shocks to sell. I sent some pm's to the guys that posted about it, but thought it would be a good idea to post here too. Don't want to buy all four if I don't need too, so if anyone wants to sell me an extra pair, send me a pm.


There's two sides to every schwartz, he got the up side and I got the down side.

The Jato's are the plastic shocks. The stock Revo's (silver aluminum) come in a pair, but the nice hard anno Revo's come in a 4 pack.

I like how this mod turned out. I was a bit skeptical at first, but seems like it fits really well.

I wonder if there is a business opportunity for Mike to make a new F shock tower to accomodate the GTR shocks, and provide a few mounting holes for adjustability. Perhaps a bit of work on the body mount as well. Considering its just a flat plate, it should be a piece of cake for him, and there are tons of .5 drivers that would go for the mod vs the very expensive DM-1 shocks.

Skeptical, how dare you sir. I originally made a front shock tower that had mounting holes about 12mm above the original ones, but I did not like the way the body was lifted up. However, it would be nice to have a tower that had two or three holes inboard near the body post holes we are using for mounting the GTR shocks. I'd like to be able to get more up travel and reduce the amount of droop.

I have the rear LXOne shocks installed in the back, but have not cut any coils. 30wt oil. Still waiting for the F springs to come in to finish it.

Ran it a bit in some rough sandy areas, and the back seems pretty good so far. It does sit a bit high, and I noticed it tended to roll on asphalt were it would hold or slide before. Its def got to come down a bit.

Otherwise I was looking at getting some lighter springs as well. My .5 has the OFNA Ex chassis and small 3S 2500 batts, and @ ~2000g+, may be lighter than some RCM ext chassis conv. Anyway...

I couldn't find a rate for the std yellow LX1 springs. So I tested it and came up with a value of 76 gF/mm (or 4.26lb/in, 0.75 N/mm (trx style).)


Spring rate converter FTW

I also found an HPI Spring that fits well. Now the package rates that as 71 gF/mm (3.96lb/in, 0.70N/mm) but I tested that as well and came up with 59 gF/mm (3.3lb/in, 0.58 N/mm.) IDK why I came up with such lower values than HPI did. My method was slightly crude, but was very reproducible.

Shouldn't matter too much, as I just wanted to get a relative rating to the other springs in that series for the Hellfire. The blue spring I used was softest, while the OFNA yellow spring seems closest to the HPI silver (soft) spring FWIW. The springs are long @ 80mm vs ~72mm for the OFNA's, but both need to be cut down anyway.

GO-Ride: How do you determine what length to cut the springs too? Why wouldn't you cut them short enough to use the stock shock mounting holes? LMK, as I don't want to trim any springs until I am sure on what I am doing. Thanks
