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.

Only part that I consider average quality are the shock boots, two where split before I even ran the buggy and the other two where went soon after.
I trialled a few other brand boots and found the Team Associated boots for the RC8 (Pt No:ASC89058 / ASC89059) fit nicely and are more durable, look good too.
Just curious why the cutout where the servo arm is on the body, does it rub or is it for airflow?

I want to try the "recommended outdoor" setup from the Tekno's website. It says to use 7-7-5 diff oil. I assume this is PT oil? What would be the equivalent for associated oil? I have heard that associated oils are thicker than PT oil but I don't know how different. I'm just trying to decide if I should just run 7-7-5 associated or if it would be too thick. Any advise would be much appreciated. Thanks!

You can't really tell by the pic, but it's not cutout there. I just left it clear as part of the paint scheme. There is a clear triangle on both sides. Although the top of front screw on the connecting arm to the steering bell crank does rub on the body shell if I add additional washers in order to make it parallel.

Take a leather punch and put a 2mm or so hole near the very top, right below the support ring. This allows air in and out as the shock is compressed/decompressed. When you assemble it, keep that pointing to the back.
Thanks, good tip.

5-5-3 associated is pretty close to that.

My buddy and I got one each from Amainhobbies and Towerhobbies.com. They have excellent service and price. For example Towerhobbies has this $60 dollar off coupon if you spend $400. So if you buy it now, $429-$60 so you can get one for $370 brand new with no tax. I strongly recommend them both.
If you want to buy it used, its a different story.

Default EB48.3 Screw and Bolt Set?

Hey all, is there a place that sells a prepackaged kit of most of the screws, nuts, bolts, etc.? I want to have extras for the coming season. I could order them individually, or go to ACE hardware and find them, but it would be easier if there was already a prepackaged set.

I found a set here. Not sure why Ebay and Amazon don't seem to have them. Then again, the Tekno site does not even have them haha. https://jet.com/product/detail/e5468...FRZMDQodC8MAoQ

Yes, but you'll have to trim either the front of the mudguards down or remove some of the body as the .4 comes with updated mudguards that are lower in the front to allow clearance for the new steering setup.
