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.

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.

All the links are the same, TKR5123, which are the steering links. So any 4mm 55-60mm turnbuckle will work

It's a little lighter, 193 grams versus 221grams, so a savings of 28 grams, or about an ounce. Also power delivery is a little different and the 4600 is probably a little easier on your batteries.

I have be
ng on the kit, and will update with pictures!

One thing of note: So far the rear camber links, and rod ends are not the same as before. The inner rod end is thinner, and straight. I wouldn't dare thread my Lunsford turnbuckles into it. The Lunsford turnbuckles are 4.75mm ROUGHLY, and the new Tekno stock turnbuckles are 3mm.
I also used the #19 drill bit picked up from ace to drill the arms in the absence of a 4mm reamer, it worked great, and is a cheap option! Also your carbon diff plates are a direct swap.

I see from the get go you do not want the composite cross pins. I have to wonder why they went that direction, I understand they may be "good enough for 2S" but it still puts a cheap feel in there.

Are the stock turnbuckles the same size as the older truck? I sold my older truck a while back but don't remember them being that skinny.

Thought I read elsewhere that other companies have used composite cross pins in their diffs for a while and haven't seen any issues with them.

Durango truggy I had came with them, I had to sand them down to get the gears to move. They were such a tight fit that the diff was locked.

While they held up well enough I still did not like them. Your diff setup should be from the fluid viscosity not the fitting of the moving parts over time.

I don't see why not. The .3 parts fit on the original 410

Don't under estimate the composite pins. They should be plenty strong and wear a lot less.

Yes, the SCT410.3 and the new EB48SL use 4mm turnbuckles and rod ends for the steering and camber links.

The only turnbuckles that are the same are the steering links. The original SCT used 5mm threaded turnbuckles and rod ends for the camber links. We tested the smaller links extensively and found them to be more than strong enough for the SCT and SL. I even ran them on my EB48 with no problems.

They're actually good enough for our ET and NT, although with the stresses those diffs see (with the larger tires) it's better to stay with metal. They are also lighter, and significantly cheaper. We did a lot of things to cut cost in smart places to keep the street price the same as the original SCT410 while offering as many of our option parts as possible (lightened outdrives, aluminum balls and bushings, fully machined chassis, secured aluminum hexes, split diff, better droop screws, aluminum center driveshaft, etc.)

We had heard this as well and were skeptical about the reliability. Once we made ours they were tested by all our drivers in all of our vehicles. If they didn't hold up we wouldn't sell them.

Yes, all of the holes are unchanged. And I believe M2C's chassis has the front bulkhead holes countersunk as well for the short bumper.

Ours shouldn't require any hand fitting.
