Welcome to the EB48.3 Wiki


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

Springs:
Low Grip Track:
TKR8772 Yellow Low Frequency Rear Springs and TKR8762 Grey Low Frequency Front Springs

Low to Medium Grip Track:
TKR8773 Orange Low Frequency Rear Springs and TKR8763 Black Low Frequency Front Springs

Medium to High Grip Track:
TKR8774 - Red Low Frequency Rear Springs and TKR8764 - Pink Low Frequency Front Springs

TKR5199B HRC Rear Hubs (L/R, CV or uni, EB/NB/ET/NT48/48.3) - Improves stability of the rear on mid to corner exit. Able to be on power earlier on corner exit.

TKR6146 - CNC Delrin Shock Cartridge Set

TiNi Shock Shafts
-TKR6017T (front)
-TKR6061T (rear)

This car is very durable. Here are the spare parts that I recommend you keep on hand:
TKR5020 Hinge Pins (inner, front/rear)
TKR6061T Rear Shock Shafts w/ TiNi Coating and TKR6017T Front Shock Shafts w/ TiNi Coating
TKR5286 Front Suspension Arms and TKR5184 Rear Suspension Arms
TKR5194 Spindle Carriers
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.

Page 3 Step K-3
Put the screw in upside down so that the head of the screw is in the hex spot that's molded into the spindle. This will aid in clearance in full droop / full steering.

Page 12 Step I-2
Use no less than 4 shims on the steering spindle to limit steering throw. I actually just use one 2mm ball stud washer from my 10th scale stuff since each shim is .5mm.

Setup Sheets:
Setup sheets for all Tekno RC vehicles can be found here.

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.

On the recommended outdoor setup, is that taper up or down for the rear shocks? It is cutoff in the setup sheet.

I have question i have not been able to figure out for over a year.
My eb48.3 bounces on hard landings. My track is rough but has no landing ramps off jumps so it slaps hard and gets out of shape. 4x1.8 pistons 475cst pt oil.
I dont remember my 48.2 doing this.
Any ideas i guess i need more pack? The rough track is another concern.
My et48 is perfect by the way. No slapping at all

Taper down, with emulsion we have been running them down. Also please check our latest outdoor setup. There was a typo on the rear spring part #.

First and easiest thing I would recommend is more droop. Second is to use our 3x2.1 pistons with 600cst oil in front and 700cst rear. Softer springs will probably help too.

I was gonna try those b pistons but figured that would give even less pack no?

Correct. The bounce you describe can be caused by too much pack.

Has anyone installed the universal drive shafts or the aluminum rear hubs? Wondering if there is any performance enhancement with the shafts.

I'm running the universals. Made the car better through the bumps.

Correct, those pistons should be less pack but combined with heavier oil and more droop it should be better on a rough track. Universals would also be good on rough track too. If you use universals be sure to run a 23f 28r ride height.

Can you post a setup sheet on your vehicles current config and also a link to a YouTube video so i can get an idea of the layout and conditions?

23f 28f seems a big diffence, why so much?

With universals this is the best ride height we have found. Front tends to lift a little and the rear lowers on acceleration. It sounds odd but works very well.

I am having troubles getting the front camber to -2deg with how short the camber links are, the turnbuckle feels like its bottoming out and binding up the pivot balls.

I checked that thanks, one of them was a turn off, so I fixed that. But I am still having the same problem.

That is good to hear. I run on a bumpy track so anything offset that would be great.
