Car malfunctioned sitting in rv storage compartment.servo fixed the problem but you must put all screws in original places and involves dismantling half the car.Okay I would like to say that this is a good product but I can’t. I have owned this truggy basher since April 2022.The durability….. it sucks… big doodoo. Yes while the part assembly is metal and provides durability the weakest part in the assembly is the spur gear which is unfortunately made out lightly machined pot metal and is not even hardened or heat treated.Ease of installation…….. pfffft ?…. Okay okay seriously though, installation isn’t that much trouble at all provided that you are mechanically inclined and have the patience to tackle replacing this because you basically have to disassemble half the vehicle and open up the differential housing just to replace these parts.Personally I think it would be wise of LAegendary to offer the spur gear separately since in my experience this is the one part that has to be replaced the most often ( Are you listening Amazon? Jeff Bezos? )Value for your hard earned money?Hmmmmm…… nope.If only the spur and possibly the pinion gears were of better quality to justify this price.This was exactly the same piece that had broken through some rough usage. It was a bit difficult to install in the small, tight area. Once complete however, it was perfect.Made for the model. Fit perfect, and shipped promptly.Great to be able to get parts as neededKids are hard on equipment, but this part fixed my sons RC car, works great again . No issues.The parts came sooner than I thought and were easy to replace. I also bought some other parts for my rc truck because they broke as well. This has nothing to do with the parts or truck being poorly made, and everything to do with me not being very nice to the truck, but thats why I bought it. It is a fast though little rc truck. You should get one.Ordered the Front CVD shaft set as an original replacement order as indicated by Laegendary. However the CVD shafts are 1/2 inch to small. Come on Laegendary, you sell this item as an original replacement and there a 1/2 inch too short, where is the quality control. If you are reading this review Laegendary, think you better get with vendor and correct situation.
