I found a website concerning the issues with the NE lifts and it stated the following:
Beware of Nitrous Enterprises

Updated 03/30/2005

Soon after they started shipping 4Runner lift kits, Nitrous Enterprises branched out into lift kits for the new Toyota Tacoma. Similar to the false advertising with the Revtek spacers, Nitrous Enterprises decided to abandon ethics in hopes of making a few sales.

Is there a problem with the REVTEK spacers that I am not aware of?

Thanks for your replies.

 

NO issues, Just NE from what I understand.
Do a search on 4th gen lifts, you will get a few options.

And now OME

 

he meant that NE used revtek spacers to lift a truck and claimed they were pics of a truck with NE spacers.

false advertising by NE... revtek is 100% OK.

 

Revtek has NOTHING TO DO WITH NE AND IS ABSOLUTELY 100% OKAY. He was just saying that false advertising was used by NE about their kits which appeared merely to use pictures of Revtek spacers, claiming to be made by NE.
