Highlights

How do you make the IR40 better? Run my LCG. Then what? How about you add an Axle?

Introducing the OR66 kit for the Injora IR40 Body. This chassis is built off the same proven design of my IR40 LCG, but then adds an additional axle and some unique details to complete your build as a very capable TRX6m.

This chassis sucks the frame rails into the body by nearly 16mm and has the skids and battery tray integrated into each 1pc frame rail. Then has a special add-on brace and railset to extend it. Specifically designed to use my High Clearance Plate it has a completely smooth underside so you won’t get hung up in those typical 4m places. The battery is held down by the clipped body itself so no more straps or fiddling to swap batteries. The camper is hollowed out and there are spots to run wires into it for those wanting to use 3s batteries. Included are LH and RH Mounting trays for ESCs and/or Receivers to tuck into the cab rather than having that mess of wires and the back of the bed. This also improved your weight bias.

Because this is a complete IR40 with an Add-on you can easily switch back to a 4x4 if you wish.

This chassis requires the use of Hightrail links for the IR40 portion, and an extra set of front Defender/ Bronco Links for the 3rd axle.
This kit comes with an Injora Ascent18 front shaft for connecting the 3rd axle as well as my 6x6 conversion kit to modify the 2nd axle into a through axle as well as flip the 3rd axle so it spins correctly with the other 2. If you are using a Diamond Axle you only need to flip the Diff in the 3rd axle and you will not need to flip it. Also included is an Injora 12t Pinion for the through axles pinioned diff cover.

You will need the following to complete:

Injora IR40 Body
Injora 12/24 Diff-set (For through axle)
4x4 TRX4m worth of parts (Trans/ Motor, Axles, Shocks, Servo, ESC, Wheels/ Tires etc.)
X1 full set of Hightrail Links/ Driveshafts, and a set of FRONT links for a Defender/ Bronco.
X1 Pair of shocks and wheels/ tires (3 wheels/ tires if you want a matching spare)
(Suggest 53 or 59mm shocks)

Lastly there are hooks built into the upper frame cradle that allow the use of a rubber band limiting strap to prevent unloading of the suspension on steep climbs. This can be used on all 3 axles.

Kit comes complete with:
Complete IR40 LCG Chassis w/ High Clearance Plate
OR66 6x6 Frame Add-on
OR66 Rear Bed/ Detail Set
TRX4m 6x6 Axle Conversion Kit
Injora Ascent18 Front Driveshaft & 12t Helical Pinion
SS Hardware
Black Rubber Band Limiting straps
Instructions/ Diagram

Note**
The supplied High Clearance plate is required for this frame and is made of 3D Printed plastic same as the frame. If you would like to utilize a metal plate be it Aluminum or Brass please see the Tools section of the store where you can purchase a High Clearance Drill Jig and make your metal plate in to a High Clearance one.

I advise using links that have the adjustable style nylon ends so you can tweak and level the rear axle pinions. Full metal or stock plastic links without adjustment can give the rear driveshaft an aggressive angle forcing you the limit suspension travel or risk the shaft pulling apart.

*Injora SS links can be ordered a la carte and are idea for these types of rigs.

Metal driveshafts are REQUIRED for this kit. Stock plastic axles will not fit the chassis and the added load of a 3rd axles as well as the weight will snap anything plastic in the drivetrain quickly.

LAYDOWN Servo recommended! You can use it with a typical stand up servo, but you won't be benefiting from the chassis nearly as much as it is meant to be a low CG chassis and needs the low profile and low CG Laydown mount to get the best performance.

This kit will be available as a complete kit which includes a full IR40 LCG kit, or as an Add-on for those who already have my IR40 and want to convert it.

**Due to the additional time it takes to prep this rather large kits they will be added to the store in limited quantities as they are completed and ready for shipment unlike my other products which are typically assembled upon order. They will be added to the store periodically, but if you come back and it’s not in the store simply contact me and I can give you an ETA on when more will be added.



Free Lifetime Replacements:

I understand that 3d parts have can be more susceptible to breaks over metal or injected nylon parts, so for as long as I am business I offer free lifetime replacements of any parts that break for any reason. Simply cover the shipping, and I can ship out any replacement part or parts you need to make your rig whole again. If you are international, I understand shipping costs more so I will give you multiple sets of whichever part was broken to save you if you have another accident in the future. All of my products evolve over time if I find a better method or update I can do to improve them. If you do have a break on an older ver. of the part, then I will supersede you to the current ver. for only the cost of shipping.

Disclaimer:
This is a 3D printed part. It is made from PLA+ Plastic. It has an inherent "layered" look and may require some slight modification if your vehicle is fitted with other aftermarket parts.
Please view my packaging and inspect the package BEFORE handing it to young children. While my logo is suggestive, it is not unsightly, but may require the approval of a responsible parent before giving it (and the small contents inside) to a child.
Due to a rather insane review I received, I need to state this, and be sure anyone else so inept HAD the opportunity to read this...

Thank you for a very good product, I used an adjustable link as described, so I was able to make a 6x6 with a perfect and ideal axle angle. The chassis is very well made and the screw installation is smooth.
