TKR8104 .4 bellcranks

You also need the Aluminum C Block (others can stay composite)

What option parts should I consider buying with a new kit?
None are required but we recommend the following:

TKR5161 V2 Adjustable Hinge Pin Brace A block, 7075 CNC, EB/NB/ET/NT/SCT) - Helps to improve durability on hard crashes.

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.

TKR6146 - CNC Delrin Shock Cartridge Set

What spare parts should I keep on hand?
TKR5020 Hinge Pins (inner, front/rear)
TKR5516 Front Suspension Arms and TKR5515 Rear Suspension Arms
TKR5542 Spindle Carriers - TKR5541B Spindles
TKR6009 Shock O-Ring and Bladder Set (for 2 shocks)

Tips and Tricks

List of Vehicle Setup Adjustments and Build Tips can be found here. There are several videos and articles detailing the building of shocks, diffs, camber links, etc.

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!

Piston Drills:
Some of our setups recommend using pistons that are enlarged. For instance 4x1.9 or 3x2.0. To drill the pistons we recommend the following:
GMK Supply Piston Drill Set
16PC Metric Bit Set Metric Sizes 2.00 to 3.00 MM.

Does anyone still run a trackstar system? not seeing much from searching the thread. Wondering is a 4850 with a 15 t pinion on 2s with the trackstar 120a ESC would work or would that overheat cause of the 4850 motor

I don't see why not. The specs say that the ESC will work with motors 6000KV or less on 2S. If it were me, I'd start with a 14T pinion though.

It comes with a plastic servo horn, most people upgrade to aluminum though. Not necessarily needed for the build though.

I bought the Tekno aluminum arm. Then I found out my Protek servo came with an aluminum arm. The Tekno one was pretty nice so I ended up using it.

I would get the aluminum servo horn. I would also get the aluminum diff pins.

The next upgrade for me would be the shocks. Aluminum bottom nut and delrin inserts.

Some people don't like the lighten star wheel hexes. As long as you don't overtighten the set screw, I think it's fine.

Are the aluminum diff pins just for better wear? I never heard anything bad about the composites.

And would you recommend the delrin inserts on a new kit?

The kit wheel hexes are steel. Some people have tighten the set screw too much breaking the hexes. I would initially stick with the kit wheel hexes.

I would definitely upgrade to aluminum a block.

Those are the aluminum diff pins. Some people have broken the plastic diff pins. That's why I recommended the alum diff pins. I never ran the plastic diff pins - I went straight to the aluminum.

The delrin inserts are smoother than the stock shock inserts. It's not a must. It does improve performance though.

Just use a little loctite on the set screw for the stock hexes and snug them up. Not too much. Works great.

Hey Guys,

I just picked up my new Tekno SCT410.3! I need a little gearing help. I am swapping over the electronics from my Slash 4x4. The motor and ESC are a Castle 2650kv and a Castle Sidewinder 8th ESC. I eventually plan to get a Tekin Setup but for now this is what I have. I run this setup on 3s and I am wondering what you guys think a good pinion to start with is?

Thanks for any help!

RPM should be comparable to a 4000kv on 2S... so, depending on track size... somewhere around 17T (+/- 1) pinion, would be my first guess.
