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.

I was also wondering if the 48.3 parts will fit the 48.2 individually? Like if I were to do one mod at a time. For example could I install the .3 arms then the .3 towers and shocks or are there certain things that need to be replaced together in order for them to work/fit?
Here ins where I got my upgrade kit. It is more like a starter kit as it doesn't have all the parts but they are available.

Thats the basic kit. You still keep your .2 caster and spindle. I think the stock .2 was 10 or 12 degrees, little more steering then the stock .3, 15 degrees trailing
I would probably do the towers and shock bodies and shafts at the same time. You have to do the carriers and spindles together, Then arms and sway bars

Correct, the .2 came with 10 spindle carriers, and the spindles were inline.

Slapjack
IMO If I were you I would wait to put any updated parts on your .2 until you have everything you need.
It's well worth it, the .3 is awesome!

There is a reason for this. The redesigned shock geometry of the .3 cars differs greatly from every other offering on the market. With the new design, the front and rear geometries are a lot closer than they were on the .2 cars. To balance the new suspension, a higher rear shock fluid is required in order to get the correct balanced feel from the cars. It is a little strange if you've come from other cars, but the reasoning is correct.

Yes, it can make the car loose. We've been running Joe's setup in order to add rear grip (as well as grip all around) to the buggies and it's made a huge difference. The farthest I would go with shock fluids to get more rear grip is to have both Front and Rear the same cst, i.e. 450/450. Using more of a "traditional" fluid setup gives more rear grip at the expense of poor jumping, landing, and stability.

Default universals

I recently upgraded to universal on my EB48.3. Today something happened that I have never seen before. One of my front wheels and the whole axle fell off. It turns out that the only thing holding the wheel/hub and axle in place is the inner spindle bearing. This one gave e way.

Servo advice is like any other, brands and opinions will abound. I will put out this guideline. Stay about 300oz/in as a minimum for durability and corner holding, and try to get .1 or faster for speed (I like the .07/.08 speeds as they're not so fast that I get in trouble, but fast enough for quick corrections, including in the air).

I've run the Savox 2274, ProTek 150t, a TowerPro that seemed to have only been sold for about a month, and RadioPost servos in my eBuggy. I liked the ProTek 150t the best. While it is more than required, I'll be putting the 170s in my EB48.3 over the winter so it matches the ET48.3 I'm building, and I run an Orion in my SCT410.3 that is also .07. The goal is to get the most similar response on them all so it makes switching between vehicles that much easier.

The EB48/EB48.2 specific thread is here.

For the upgrades, there are some that can be done on their own, and others that have to be done in batches.

You need to do the arms/hubs along with the shocks. The towers really should be done at the same time as well, since if you use some of the shock mounting positions with the old towers can be damaging to the shocks (shock bottoms out instead of the vehicle on a hard landing, sending all the force into the piston and shock shaft). The spindle/spindle carrier need to go together, but don't need to go with the others.

Others you can do or swap in and out as you see fit, such as the new hinge pin braces, the lower wing mount, etc.
