Default Has anyone run any KMJ Performance parts?

These guys have stuff all over Ebay and it's crazy cheap - kinda seems like one of those too good to be true deals. They sell shaft mount rocker setups for under $200!!!!

Understand this, they sell products, for a good price, but they sell what is out there. So, the junk cheap products and junk, and the name brand products are great. So, i have used them with great luck so far, several times. But i did not buy junk. those shaft mount rockers? I seen them set up by a pro, 1/2 the shafts broke on start up.

I'm with Zones on it though - if their products sell that cheap - then they are probably not quality parts. I just wondered if there was anyone out there that had any good luck with them. I'd hate to spend $200 on a set of their rockers brand new when I can get a set of good ones used for the same price.

Ask yourself this, if you cannot do it right the first time, can you afford to do it again the second?


I have been warned about those knock off bolts/studs, not worth it.

i have a set of thier pro-comp elctronics 5140 rods in a mild 355 with the old camel humps on it ( 9.75:1 compression).. the rods measured out with perfect clearance and very consistent, and they have good cap screw bolts, the rods looked pretty good for the price.. now the quality of material used might be a different story, that i dont know yet..


i am debating on using a set in my lt1 build, i might go up to the H-beam rods though, they're like $250, the 5140 rods are like $150. Mine come from speedway motors

wish someone that have used the rods would chime in, i'm interested also..i have looked around on the internet and havent found much about them.

No experience, and will NEVER have any experience with company's like this!!!
I do however read a lot, and help young racers on several forums, and this place is ripped apart all the time,
as mentioned, because people buy the stolen, counterfeit crap from company's
that make copies of other company's property.

Do yourself a favor, buy from the original designer, that actually care about their reputation,
and don't have a huge failure rate.

I know this thread is old, but figured I'd bump it.

I needed an oil pan for a roller 355 I'm building. They had one for $65 shipped, which compares to a similar Moroso for $175. It's been like absolute hell to try and return this thing, (28 days working). I've called and spoke with the same guy 4 times, emailed him the requested pictures twice, and he claims he can't see the bent rail. Supposedly a shipping label is inbound to my e-mail.

Cant see the bent rail? You be the judge.
