Anyone happen to have a copy of the spec sheet for these?
And is 220 still the magic number for the final Torque value that hopefully won't crack the block?

Does anyone still sell or use these?

The website still has NL and MPD as dealers.
Did these not end up being good? I know the Cummins crowd really liked them.
Mine have been sitting in my closet for 2 years, now that I got my lift installed I was planning to finally pop the cab and install them

I have a set in my 6.0 that are holding up great. Was planning on putting a set in my 6.4.

call in the am and i'll get you specs.

we stopped using them when A1 got revived by a new owner, so now we sell A-1 h-11 again. Extreme was the best option when there was no A-1 .

So A1 technology is back open? I'm surprised there isn't more talk about this.

Me also
i can't find a website nor much else

i was wondering why there was a endless supply of NOS H11's though

but i heard ARP had bought them out so this makes little sense ?

Maybe bigrpowr can give some insight on who owns them now.

Anyone else still using these guys?
I have been super happy with them in my 6.4, wanted to order a set for a motor I’m doing for a guy, but the price is now close to $700 bucks!
I remember when they were around 450-500, the last set I ordered was $600.
Just curious if that’s just MSRP or actual cost now days
