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 would go with 50c and up. Smc, promatch, protek, reedy, and vant have all worked well for me. Great price on these:

There are many good batteries and companies (as well as many bad ones). One of the best bang for the buck companies to deal with is generally SMC. Either the 5200 or 6500 packs here are fairly common in eBuggy vehicles. I generally run the 6500 as I will never ever worry about power or the pack being stressed or being able to make time even if the main is long and there is a long warm up period and long after lap in a qual. The 5200 should balance the vehicle more side to side, though I haven't found problems from that with the 6500.

i know this has probably been asked before, but im not having any luck finding anything. is there a list of things to buy to update the EB48.2 to the EB48.3 or does someone sell everything as a kit? my .2 is ready for retirement after a full season of outdoor, and i can either drop $500 on the .3 or spend a few hundred and restore my .2 but if im going to be buying parts for my .2 id rather just upgrade it to the .3 if thats possible but i dont know all the little tiny details that are different and what goes with what because they changed so much

Take a look at Joe's setup from Wicked. A lot of guys are running the same setup on both the NB and EB (benefit for those that drive both) with similar driving styles. You might have to soften up the rear a bit if it's blown out. I'm currently using yellow and 450.

I was referring to Joe's setup if you wanted to give that a try. I found the back end a little stiff and went slightly lighter on oils and springs.

To get the basics of the .3 on your .2, go here. http://www.fiercercsolutions.com/Tek...kit-FRC010.htm

That kit will give you the new suspension geometry, but you won't have full .3 adjustability. That being said, just the upgrade is a NICE addition.

To get the suspension adjustability, go here. http://www.fiercercsolutions.com/SCT...kit-FRC008.htm and that will complete you, so you can use all the .3 upgrade sheets.

Only other thing that isn't necessary, but is nice, is the split center diff. http://www.fiercercsolutions.com/TKR...un-TKR5261.htm That's for the aluminum one. They have a composite that will save you a few bucks. But if your gonna spend the money, just do the aluminum.

I just got my kit. The build seems pretty easy to follow and build.

Just take care not to over tighten screws, and it should be a piece of cake. Let us know if you have any more questions

Just grabbed .3 kits (eb,et,sct) are there any part issues still drive shafts etc to worry about or is all that fixed? I'm not going to be able to race these kits until Rama in Feb so I'd like to get ahead of issues so I can have Fun racing at the event. TY Several guys were having issues w/ shafts at the end of the summer locally, only reason I'm asking.
