TKR5545B HRC Rear Hubs (L/R, CV or uni, SCT.3/SL) - Improves stability of the rear on mid to corner exit. Allows harder acceleration on corner exit.

Setup Sheets:
Setup sheets for all Tekno RC vehicles can be found here. Please be sure to try our recommended setup. It works very well on most tracks.

Warranty Policy:
Tekno RC is the only company in the industry that will give 50% off of parts if returned to them using the General Warranty return policy found on their website. The parts can be lightly used or completely abused, as long as the part is still being produced it's covered!

a set screw will definitely take care of the issue but I believe it would ruin the threads on the main screw also. When ever you back out the main screw it will ruin the plastic threads in the part. I guess for a little longer term solution it will work but be prepared to replace all the pieces if you ever have to pullt he screw out. The screws always back out on mine also so I just check every few runs

I have a sct410.3 and a sct410. I have most of the basic upgrade parts to bring the 410 up to the 410.3 specs. Is the angled rear gearbox a worthwhile update? And are there any modifications needed to run the lcg motor mount? Thanks!

So what seems to be the hot ticket for carpet springs?

The angled gear box will help minimize the wear on your rear drive shaft and outdrives. The lcg motor mount is drop in. No mods required to fit in a standard SCT motor. If you want to run a 1/8 motor then you have to trim one of the screw holes on the side guard.

Are all the upgrade parts worth the money and effort? Or should I just practice more with my existing setup (one of Jeremy McGuigan's) . I'm debating this in my mind right now. A fast guy at the track did all the upgrades but he's fast regardless of the tricks.

Springs are something that are worth dialing in. Depends on track conditions some are better suited for different conditions...generally stiffer ones do better on smoother higher grip surfaces and softer for rougher and looser situations.

The aluminum hinge pin braces are a good upgrade for durability reasons. The front A block is usually the first to go IME.

I never broke a steering rack but have heard other people doing so. The aluminum option would be a durability upgrade.

Most of the upgrades IMO don't make you faster just more durable with the exception of the springs.

What about the new Ackerman? It's supposed to turn better? Same with new hubs. Just wondering about people who did all these upgrades, if it improved lap times. I was interested more in that than durability.

I switch over to the recommended indoor outdoor setup which has both the items you mentioned and the truck is absolutely amazing on an outdoor 1/8th track. I would highly recommend this setup if you are racing on an outdoor semi bumpy med to low traction track. I have not tried this setup on indoor clay but the title of the setup suggest it might also work there. I did try it on carpet and didn't like it. May have been able to mess with springs and droop to get it there but I just went back to my known good carpet setup.

The set up works great on an indoor clay track.

The steering upgrade, Low Frequency springs and pistons are a must. I'm running a slight variation on the recommended ouutdoor / indoor set up, but the truck is silky smooth and jumps very well.

I only use my truck on an indoor dirt track. I'll probably get the parts and do the upgrade. Thanks.

Sounds like it's worth doing for me. $79 plus shipping for hubs, pistons, bell cranks, ackerman, and springs. Also I'd need new to go emulsion on the shocks.

Thanks!

Ran a version of the Munn setup for astroturf but on carpet.

I used Xray gray springs however as I have in the past. Carpet is grey ozite we use however slicks or similar due to rules. I used the associated stock SCT tires as they work quite well without needing sauce.

the issues I want to correct are this:

- car feels like it wants to over rotate. I need the rear to be a bit more planted but still off the ability to steer quickly as its a tight track
- Vehicle has chassis bounce on jumps. I am using 8 x 1.4 pistons versus the setup sheet 6 x 1.5 . I am thinking of going slightly lighter on the shock oil. but, maybe I should go 6 x 1.5? Would that offer slightly less pack?


Is there a carpet setup out there people are using that they recommend?
