| Installed 80mm Big Bores on my Ultra.
*NOTE - I highly recommend installing a 3/16" piece of fuel tubing on the shock shaft. This will prevent the shaft from impacting the diaphragm inside the shock. Having spent the last four years running Toyzukis I've grown very fond of modded big bores. I was very unhappy with the factory shocks so I decided to look elsewhere. Tried the Pitbull Kroniks; however, I was unhappy with the spring selection. So I looked to my past. Turns out the Traxxas 2659 is an 80mm Big Bore. After much searching, waiting, and more waiting I finally got my hands on four sets of these beauties. They're so old they even have the early 2000s Traxxas packaging! Anywho here's what I ended up with: Traxxas 2659 Big Bore (medium) shocks Hot Racing Mini T Springs No load spring cups by Nate Team Associated 80wt shock oil RC4WD Mini rod ends Z-S0398 Now I can experiment with tons of different spring rates almost on the fly! My spring cups have a slot in them unlike other no load cups. This means I don't have to remove the rod ends to change springs (what an asinine design). P.S. I've got some Rit Black Dye on the way to correct those rod ends. Sent from my SM-N960U using Tapatalk Last edited by GTSLOW; 08-23-2020 at 05:25 PM. |

I mod and build these on the side for friends. Here's a look at how much darker the andodizing is on current Traxxas Big Bores. I totally dig the light grey of the past! Sent from my SM-N960U using Tapatalk |

I run these on my 10ii with f9 portals. I had to get new diaphragms as mine had leaked out the oil in the package and were all powdery white. Traxxas was super helpful and I too am a fan of big bores

I love the old school packaging! I also love the older color. I'm going to have to try some Big Bores on a scaler eventually. Traxxas does shocks right. No load spring cups by Nate - who is Nate? Last edited by JatoTheRipper; 05-07-2020 at 12:08 PM. |

So I picked up some Rit Dye and fixed the ends. I can't believe how well it worked! Sent from my SM-N960U using Tapatalk |

Traxxas shocks are amazing! The cups are printed by me. Shoot me shipping costs and I'll send you a set. My cups have a slot so you can easily swap springs. Sent from my SM-N960U using Tapatalk | |

Apologies for being slightly offtopic, but what body is that you're using? I love how clean and simple it is..

I’m glad that I’m not the only one finding that the Kronik shocks have not the best spring. They’re definitely too hard for my liking

Man, those are some nice looking shocks! I do like the lighter shade of gray! I have a set of Dravtechs on my PRO. By the looks of those big bores, I may have to pick up a set to put on my Origin. I've had great luck with the Traxxas GTS shocks and use them on most of my rigs. Traxxas definitely knows how to build great shocks! |

Wow I need a set of these! The stock shocks aren’t really cutting it with my rig. The heavier springs from the incision tuning kit help, but big bores would definitely be more ideal. Sent from my iPhone using Tapatalk |

After reading bad reviews on the FB groups about the Incision 90 and 80s I didn't even bothered building mine. X seals are supposed to be great but something isn't durable about the ones VP uses. With these you have a huge selection of mini t springs to play with. I'm loving the Hot Racing ones. | |

What did you use for the caps + rod ends? Drilled yourself or dlux?

For my part, I've bought 2 sets of these (so 4 shocks), originally to put on a TRX-4. This does not work - In the front at least the shocks are the perfect length to have zero travel up or down Luckily my C2 comp truck sits perfectly with them, so... silver lining | |
