The diameter of the special cap and housing are 5/8" smaller than stock Ford distributors providing extra room in front of the engine. The new MSD cap features spark plug style terminals and is firmly screwed down to the housing. The distributor relies on MSD's race proven magnetic pickup and precision reluctor to deliver accurate trigger signals to the MSD Ignition throughout high rpm. The reluctor assembly is turned by a hardened steel shaft which rides in a sealed ball bearing for high rpm stability and endurance. Mounted to the top of this shaft is a fully adjustable mechanical advance assembly. The rate at which the chro-moly assembly advances the timing is easily controlled by changing the supplied advance springs and stop bushing for total advance.

So excited for results, feels like it’s working!
Size: Medium, Unit Count: 4
First time trying them right now as delivered today. Originally thought was supposed to wear all night but glad to find out 30 minutes just because my dog sleeps on my feet over my sheets! These silicone socks feel great and I trim my toe nails short enough they seem very durable and unlikely to rip like the pic review shows. I am confident my feet and heels will much smoother after first time wearing! I do have acrylic nails so I will be careful Putting the silicone socks on and off. Just as easy as the video the spread the lotion inside the socks and rub it around, mess free!!

Actually, better than I expected!
Size: Medium, Unit Count: 4
These are better than what I was expecting based on the reviews. I do put them on carefully because someone said you can’t tear them so I’m careful putting them on, but they almost don’t feel like you’re wearing anything as long as you don’t put them too tight on your toes. I can put lotion on my feet and I know it has to soak in because there’s no place else for it to go like socks or my bed.

So so...
Size: Medium, Unit Count: 2
They do what they advertised. You can NOT walk in them you will stretch them and pop a hole in them. You cannot sleep in them unless your going to wear larger cotton socks with them to keep them in place. They are easy to wash and dry which is nice. I will need to buy another pair. Great if your gonna watch a movie or binge TV in.

Great for dry feet or to help lock in moisturizer or medication
Size: Medium, Unit Count: 2, Size: Medium, Unit Count: 2
They’re stretchy and don’t feel goopy, I use them daily and they’re working great they keep my feet nice and hydrated and soft. I’ve been using them along with lotion to help hydrate my skin so they aren’t rough during the winter. They are comfy and if you must get up they’re grippy and don’t slip or slide they stay put. They’re super easy to put on and take off.
