Heads up, they go on snug. BUT THEY DO FIT. You just need to be careful to get the differential pin inserted in to the the end the of the driveshaft without damaging any part of the vehicle. It takes just the exact right amount of force to get it to go in but it goes on. I was nervous, but I didn't use too much force and nothing broke, and they're on. If you're really worried about that, just pull the rear end apart. They fit, either way once it's back together.Comes with grub screws. Use Loctite, just because. My WPL-C24 had flat spots milled on the shaft posts coming off the transmission. They are very positively locked down. I also put a drop of 3in1 on each U-joint. It helps lubricate the metal/metal friction and seems to make the movement very smooth.I am happy to report they do not hit the motor. They are close, but they sneak right in underneath it with barely enough room to spare, but they do fit! They are considerably quieter than the factory shafts. No plastic-y sound when turning, just sounds very machine-like.As for torque, they have definitely increased the overall acceleration capability of a stock truck just by way of rigidity: plastic versus metal. There is minimal play in either of them, so the tolerances are very good in these. Far less u-joint slop than the originals. That means much better response to work.If you're tricking out a WPL C* of any kind, go for it. These are good.

Installed on a RTR WPL C24. The rear shaft is on the fence of being too long with the 180 single speed gear box. It doesn't effect anything but it doesn't have any inward play on the slip joint portion of the shaft. Other wise they're good quality shafts.

UPDATED REVIEW: After installing them and removing them 3-4 times on 2 sets if axles, they are going back. It causes a rotational binding when the RC is in motion. Forward and backwards, doesn't make a difference. I swapped front to rear and it also made no difference. I put the OEM plastic shafts back on the C14 and it worked perfectly again.THESE ARE BEING RETURNED.ORIGINAL REVIEW: I haven't used them yet due to some issues with my Sharegoo axles but they look and feel great.Significantly better than the WPL original plastic shafts. Can't wait to get some use out of these things!

Had to drill out the pinion shaft holes a bit to make fitment possible.These metal drive lines don't spin when at an obtuse angle, they " bind up"! Don't waste time unless you like dinking with something that doesn't work

These drive shafts are awesome super solid and really cool they make the super weak stock drive shafts no longer an issue. It does not come with the proper tool to install and also they do not as advertised through picture. they look like real drive shafts they don't look like the picture that's shown. really strong drive shafts though would recommend.

was driving the truck and the driveline fell off. you need a lot of Loctite so the screws don’t loosen you can see in the photo that it fell off and there’s a lot of vibration and noise with these drivelines

Without modification this will not fit your c24 and it may break parts if you try to install, like mine

These are to long for a WPL C24
