Welcome to the SCT410.3 Wiki!

7.26.17 - BB
In order to run the recommended team setup, you need the following optional parts:
TKR6106 Orange LF Springs
TKR6114 Green LF Springs
TKR6018 composite shock caps (built to emulsion) OR TKR8702 Aluminum Emulsion Shock caps
TKR8027 Shock Stand Offs
TKR6051 8x1.3 pistons(drilled to 1.4mm)
TKR8104 .4 bellcranks
TKR8100 .4 ackerman
TKR5545B HRC Hubs
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.

TKR5163 – V2 Adjustable Hinge Pin Brace “C” 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

TiNi Shock Shafts
-TKR6004T (front)
-TKR6017T (rear)


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.

Use steering stops/limiter washers... more info here.

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!

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.

When we had tekno shafts in our Traxxas slash's the shafts came with o'rings for exactly what your saying. Were still noisy as heck ..

Is there any up grade for more of a automotive style universal joint. This pin and a slot design really blows..

Yep, that's what I meant.

What's wrong with the pin and slot design?

I ran mine for over a year before they wore out. But I also serviced them regularly.

as you can see from the plethora options for pin and slot alternatives, scaling down anything from the 1:1 world is not easy, simple, lighter, stronger, cheaper, or better.
I have seen some CV joints that use ball bearings, but there were some negatives to them. Weight, and the need for suspension travel are all barriers.
MIP make their CVD kits, but they are tanks needed to be strong enough. They use a sliding shaft to account for suspension travel.

If I understand you correctly, yes, you want the o-ring in the inside groove of the pre-load adjuster. It will give it just enough friction to keep the adjuster fro moving unintentionally.

Didn't see a groove on the stock plastic adjusters and don't have a o-ring, that was my concern, that the adjusters would be free to move without it

The plastic ones have enough resistance that they are not needed.

No, my statements aren't opposite, just not defined in regards to what they are doing and or why.
I never stated you want a cold battery, but you dang sure don't want a hot one either.
They are essentially just warming their packs up to get the chemistry to release electrons more efficiently due to thermal expansion.
But... There is a threshold for which is optimum over a run. Being to cold as well as to warm will exponentially decrease your performance.
Additional caps them selves are important to further normalize the voltage and amperage output to prevent crossing said threshold.
Trust me when I tell you a cap pack WILL make your setup better!

Yes, I put an o-ring in the outdrives. There's still plenty of play to accomadate chassis flex.
