GMPP and the Warranty

[Redwolf20]

So I am finally close to getting my car after a 10 month wait and among the things I want to do is a cam swap.

Now GMPP offers the Stage II cam for the LS3 and seems to be what I am looking for. Now my brother, who is a GM tech at a dealership was going to install it at the dealer so I was curious whether it voided the warranty.

The install of a GMPP cam by a GM tech at a dealership WOULD NOT void the warranty but here it comes....

The tune that would be needed to use the cam properly WOULD void the warranty.

Huh? Why on earth would GM allow a GMPP cam change DURING the warranty period and not allow a GM certified tune by a GM tech at a dealer to go with it when it is, pretty much, a required step afterwards?

I don't know where you heard that the GMPP cam would not be cause to deny a warranty claim.

Like many other aftermarket parts if the installed cam (GMPP or other) is proved to have caused a failure then GM has can deny the claim.

What a dealer warrants might differ if they choose to take that responsibility.

Hope this clears things up.

Cleared. Thanks Robin!

Still changing it though!

Hmm...So you are saying that GM can/would deny a warranty claim in the event of a failure related to a GMPP cam install?

I was also considering a GMPP cam, but if this is the case, why would anyone ever buy any GM performance part?

It is no secret that in most cases, (exhaust, cam, cai, etc.), an aftermarket third party performance part is both cheaper and provides a greater performance gain than GMPP. If you are not "paying to keep your warranty" then why pay more for something you can get better results from if you go with the aftermarket? ( I am mostly referring to a GMPP Cam, as it seems to be the general concensus on this forum that the GMPP hot cam leaves much to be desired in horsepower increase.)

Not trying to sound mean about that, I am just shocked that the cam would be cause to deny warranty.

Which point are you trying to make?

First there are a lot of people who buy cams and components from GM Performance Parts. The reasons vary but GMPP has a long history of providing the aftermarket with parts that go the distance.

I am aware that there are many who believe that the aftermarket improves or sells "better" components. I do agree that the Hot Cam (whose design is a little dated) isn't the optimum cam under certain circumstances. The cam does make decent power and is very easy in the valvet train. It has a short lift compared to many popular cams. This lobe design passes the GM Performance Parts durability testing in the LS3/480 engine.

GMPP has developed anew line of LSX cams that should be available after the first of the year. More splits as well as some wider lobe seperation angles should enhance the choices.

GM Performance Parts are not specific for new GM cars. Most of what they sell is to average Street Machines, Pro Touring, Street Rods and Muscle Cars.

At the SEMA show GMPP introduced the E Rod line of crate engines. These are emissions legal crate engine packages.

GMPP is able to provide many OEM components at competitive prices. The L92/LS3 is a good example. If you told me 10 years ago that you could buy a head casting that flowed in excess of 320 CFM for around $200.00 I would say you were crazy. Try and match that in the aftermarket.

BTW, I did the dyno testing for an article in a recent issue of GM High Tech Magazine. We tested 11 cams in an LS3 engine. While the Hot Cam wasn't the winner it held it's own.
Also be very careful about what you hear as "consensus" on this or any message board. There are a lot of arm chair experts with little actual experience.

There are many shops on here with the experience to recomend a good combination.

And to address your first question, yes GM could deny a warranty claim on a GMPP cam if they can prove or feel as though it caused the problem.
