2PCS Aluminium Alloy Universal Rear Drive Shaft Upgrade Accessories for RC Car 1/12 Wltoys 12428 Fly fy-03 Desert Falcon CVD Universal Joint

Fits WLtoys 4x4 1/12 scale crawlers etc. Perfectly, much better than the original plastic junk.The Allen wrench is a nice bonus, as some of those smaller sizes of hex screw can be hard to match up to the right wrench

Absolute garbage the plastic original piece was 100 times better actually broke because of bashing, broke both replacement “upgraded” one on first runs without pushing greased and all both broke inside pins instantly do not waste your time and money.

Installed on my sons RC buggy. Installed easy enough. Ran through 3 batteries. The pin in the CV joint must have broken and the outer shaft fell off. Tried to use an old pin off the original shaft, but the hole was so rounded out that the new shaft is junk. Good thing they sell them in pairs and with extra set screws. We bought this car in August of 2020 and the original shaft lasted a heck of a lot longer!

Drive sass 10 to break under easy use at the coupler. Had to use all the pieces from both driveshaft to make one usable one hopefully this one doesn’t break like the other ones did so easily. Look for a better product

Will not take any torque. Out of balance. Then 30ft away only front tires spinning. Because the shaft has already slung out.
