Interstate Mcbee Inframe Kits for Cat

In my opinion, its best to always use OEM parts. You get what you pay for.

 

Well cat parts aren’t what they used to be...

But don’t know anything 1st hand about that companies kits......

 

Only orginal cat parts for my c13 ,1505000 miles and not rebuild

 

I don't think anything is made the same anymore. I remember when I was a kid we bought a refrigerator it lasted 25 years... Now your lucky if one lasts 7 years

 

Long story short, I we tried 2 Detroit kits and a Interstate McBee kits in my engine. The short time I ran it, the McBee kit had less oil usage. On the dyno, zero difference. Detroit actually bought 2 kits, one for my engine and one for them to study. Yes even Detroit tried aftermarket parts in my engine. Later to just give me a long block. I never put more than 30k miles on it. Seems alot of oems could care less about supporting old platforms. My experience with cat is the quality is junk and they could careless.

 

If you think OEM Caterpillar is junk, avoid their Yellowmark parts.......

 

I'm not familiar with Yellowmark?

 

Used to be called Cat Classic Parts. Bought a Yellowmark spacer plate for my 3406. Less than half the price of new. Right out of the box it was warped. Measured it and it was really wonky. Thou or 2 above spec in 1 spot, thou or 2 under spec in another. Figured it couldn't be easy to screw up a flat piece of steel but apparently it is.......
