Profiled – 1/10th truck insert – inner and outer cut – medium – 2pc.

Part # – 3205-1

(Fits all 2.2” Racing Truck tires)


Profiled – 1/10th buggy rear insert – inner and outer cut – medium / round – 2pc

Part # – 3206-3

(Fits all 2.2” buggy rear tires)

Tire inserts are one of the most critical aspects of 1/10th off-road racing.  Racers have asked JConcepts for a firmer and more durable insert and after much deliberation the new JConcepts Profiled insert is ready.  Having the insert with proper density for track conditions pays dividends to the racer and especially toward the end of races.  Starting on too firm an insert, the driver feels “on edge” during the first run or subsequent runs on a set of inserts.   Starting on too soft an insert, the driver’s vehicle is not responsive enough or runs the risk of too much insert breakdown during the tail end of a tires life which creates a squirmy or inconsistent feel.   Having the feel that is just right requires a bit of balance of durability and hardness.    To add to the construction and performance, JConcepts has added cut / grooves into the inner and outer profile of the inserts to add an even greater driver to track feel.   JConcepts is just right and always on target with the new Profiled insert.

The 3205-1 insert for 1/10th Racing Trucks was debuted during the 2012 Cactus Classic and has been used in a testing phase throughout 2012.   The material and design is very similar to the popular 1/10th buggy rear insert, part number 3206-2.   The medium to firm feel combined with the correct inner and outer sizing and profile makes a perfect complement to the JConcepts 1/10th Racing Truck tire line-up. 

The 3206-3 insert comes on the heels of the success of the 3206-2 insert.   The -3 insert as it is called, utilizes the same inner and outer cuts as the -2 but with a slightly rounder profile, the insert rounds the shape of the tire slightly which is advantageous in loose conditions with treaded tires or when using slick type tires.


  • Contoured shape with inner and outer cuts for race feel
  • Superior medium / firm density material and construction
  • Precise contoured manufacturing
  • Insert longevity, can be reused
  • Water resistant
  • Dark blue color for easy identification

Part # – 2170

SC10 front axle for 12mm hex conversion

Part # – 2171

(Fits SC10 line, requires #9880 AE steering block)

One of the best upgrades you can make to the Team Associated line of vehicles is a conversion to 12mm hex wheels.   JConcepts has been on top of this conversion since its introduction with hex adaptors and Mono wheels.  A critical point of the conversion revolves around the front axle and surrounding geometry.    Within the steering block the space is very tight and especially between the 2 front bearings where the front axles rests between the bearing bores in 1 plane and the king pin in the perpendicular plane.    

The JConcepts front axle design is based around high-quality steel construction, an outer bearing crush step and an inner 4-40 locknut for security.    The design eliminates c-clips, screws and other items which are hard to detect of issues which limit performance.    The free spinning design includes axles, 4-40 mini lock-nuts, thin axle shims, decal and assembly instructions. 


Assembly –

Assembly is built from the outside in.   Slide on the outer wheel bearing from the outside of the axle and slide assembly through the (AE #9880) steering block.   Insert the roll-pin from the outside and slide on the hex adaptor.    Holding the assembly by the hex adaptor, slide on the inner bearing along with thin axle shims and secure the entire assembly with the 4-40 locknut.    Check for the intended amount of free play and spin the axle to check entire assembly. 


  • JConcepts design and function
  • High-quality steel construction
  • Design eliminates frustrating components
  • Includes mini 4-40 locknuts
