3D Printed 5th Wheel Dolly Trailer Coupling Kit 

Approximately 1/16 scale, modelled to fit WPL, JJRC, Heng Long etc. size RC trucks and trailers (53mm between inside of chassis rails). Full kit to convert an existing trailer. You need your own axles and suspension. It can be built with a single or tandem axle setup using the standard WPL suspension parts. The 5th wheel is on a pivoting platform so the trailer can tilt backwards and forwards. The lifting drawbar and pivoting hitch give a very stable towing platform that follows the vehicle very well even in off road situations. Have fun reversing though.

Compatible with my other tow hitches used for other kits. 

Fitting requires basic modelling tools and skills and requires some self tapping screws the same as are provided in the vehicle kits. Fitting requires basic modelling skills and tools. Depending on your exact model you may need to drill the chassis and/or rear bumper to fit these parts. Some pieces are printed on a partial brim or "lillypad" to help them adhere to the print bed. They are easily removed with a knife or pair of snips

Please be aware, for this towing set up to work, the dolly wheels (ideally all trailer wheels) must spin independently. I found the easiest way to do this is to simply cut the axle shaft in half straight through the gear

Kit includes: 
5pc Dolly assembly
Tow hitch
Stainless nuts, bolts, clevis pin and R-clips
