www.kmjent.com/ is a distributer of procomp parts,after recieving a EFI distributor from them It was faulty leaking oil up and out the shaft resulting in oil under the cap of the dist. After speaking with 'jon' from KMJ he refused to accept my return stating this "If I refund your money for this I will have to explain to my wife why I have no job" very weak excuse for a very weak product. I have heard nightmares about procomp parts and will never buy anything made by procomp again and will never order from KMJ performance, no matter what they sell. Very bad buissness practice with very bad parts.

Woah! i thought i only had bad luck with them. I ordered a distrib, no oil leaks here but the car ran like crap. massive backfires, crazy idle, but the stock one ran beautifully after i removed this procomp junk. i emailed them and they got me a replacement ignition module (free and i though great service!) so before i get the module i ordered a mini starter because they took care of me good. So i get a new module, new mini starter, get them installed and the car still ran crappy, installed the original distrib and back to smoothness.

then after a weeks worth of use the starter gave out. i paid around $80 for this starter, and after emailing a rep i would get a refund for the price with out shipping, so there i was out $10 plus the $15 to ship it back. and if i wanted a replacement i would need to send them another $15 so they could ship a new one. so because their starter failed i would be out $40 extra.

I didnt send anything back because i figured it would not be worth giving KMJ money for a product that fail and one that never worked. no more KMJ for me

I live near where these guys are based (Ames, IA) and they are a complete scam. I have heard nothing but horror stories from people locally about their business practices. Their cylinder heads have poorly finished castings and their SBC intake manifolds leak. Their customer service is terrible. They also have an "F" rating from the BBB. In all cases the BBB investigated, KMJ Performance simply ignored them.

Stay away from these guys. If the price is too good to be true, it probably is.

have one lying around from the PO who installed it, the shaft size is really small, engine stumbled and idled erratically hot...stock one runs smooth as silk, a true piece of crap

I bought a procomp mechanical fuel pump pushrod from KMJ and it was worthless, it clattered and made a ton of noise not to mention a 2psi drop in pressure. I never bothered with contacting KMJ after hearing about their poor CS

I would call procomp and talk to Baldur Castro about parts breaking or going bad.

I had 3 items go bad 1 rocker shaft crack but only when I rev pass 7200 rpm
this could have broken because I did not have a stud girdle.

But they replace the rocker, still using them only now with a stud girdle for about 6 months now.

I broken a, MSD, Mallory, distributors before cost a lot to repair.

1 thing I learn try to have your motor built up so all your parts are in warranty because if you install new part out of warranty man it cost a lot to repair.

I broken procomp dristrubutor out of warranty they sent me 1 free any way.
I only pair $46.00 for it. This was last year and bought 2 more for other motors I have works find so far.

The 1 motor make's 526 hp small block chevy.
