I'm piecing together all the stuff for my winter head buildup, however currently i'm at cam gears. I've searched for everything else, but when i searching for cam gears i found a lot of for sale threads, and not much of anything else.

So my question is: are all cam gears created equal? i want a quality product, but i think it's stupid to pay $300 for Todas (for example), but at the same time, can i trust $19.99 ebay cam gears? I just need adjustability for my Blox B's. what do you guys use, and what do you recommend?

Thanks in advance.

 

The only difference I can think of is the better quality cam gears won't let the timing belt slip off as easily as the cheaper qualities.

 

Most are very similar. The differences will be in the tolerances, and materials.

The one exception (since my preferred ST Corsa sprockets have been discontinued) would be the Bisimoto sprockets, which feature a semi-locking design that is far less likely to slip than any other brand.

They're a bit pricey, but Bisimoto would be my current choice.

oh wow!! yeah they're pricey. $260 for a pair

however i do like the peace of mind knowing that they're "impossible to slip". I just don't know if i can justify paying that much, considering that i paid only a few bucks more for the cams they're going on

 

Yes, I agree that the price really should come down a bit, but at least these offer some sort of advantage, unlike the expensive JDM brands which are essentially the same as any other sprockets.

 

I love my Skunk2 gear on my D. They have two different designs, and I'm using the more expensive version. I think I got if for something like $110, so a pair shouldn't be too bad. Much better quality than the old AEM 3 bolt one I used in the past, which eventually exploded around the cam.

 

Most of the really cheap "ebay" special cam gears Ive seen are not exact at all....in fact, you could see different spacing in between the degree marks (like two would be really close together and the next really far away). I'd stay away from the really cheapo cam gears, but any name brand like skunk2, fidanza, new AEMs, buddy club, golden eagle, etc will be about the same.

 

Our cam gears are VERY expensive to manufacture, and the cost of a piece of mind is priceless! When a cam gear slips, it does cause more that $50 in damage. The patented serrations eliminate that issue...even with one bolt in place, it is impossible to slip! Our B and H designs are $260 a pair, and the D, EW1 and F units are $130.

For the technology involved, and the the safety advantages as well...they are well worth it:

 

i like the Golden Eagle cam gears.. i do not like the skunk2 cam gears as i had one of them come apart on me and destroy my motor.. and now the replacement Skunk2 ones that i got are off! marks on the gears never line up!!!.. i don't know what the hell is going on with them but they are definitely junk...

Which version skunk2 cam gear did you have? Exactly how did it fail?I'm debating now if i want to buy the proseries....

 

Even though at a glance, most cam gears look similar, when you actually compare them side to side (or even take them apart), then thats when you start noticing the differences:

- What are they made of? (Most are cheap aluminum machine cuts. The expensive ones are forged)
- Are they balanced? (and if so, upto what rpm?)
- What measures do they take to prevent the inner ring from slipping? (designs like bisimotos, number of bolts etc)
- What measures do they take to prevent the timing belt from slipping? (what surface coating is on the outer ring? is it textured?)
- How accurate are the timing marks? (to what degree increments are they adjustable? 0.5deg? 1deg?)
- Do the TDC marks lineup? (what use is a cam gear if they don't?)
