I make and sell stuff. I have every bearing and seal for gen 3 and 5 SuperChargers including rotor pack and case needle bearings.

In the past, I've been asked....

where I get my materials.
What the part numbers are.
I've eve been asked for my electronic drawings.
I have the part numbers, I have some seals and I'm the cheapest.

I invest a significant amount of time into this because of business like ZZP and Jonbondperformance.

I have more than 20 hours into your $5 seal.
