will a aftermaket coilover kit install void my warranty??
thanks in advance.

 

legally & technically any mod will void the warranty.

it's all down to how nice the dealer and the DSM is.

 

That may be how it works in actuality.. but 'legally & technically' NO mod can void your warranty. It should only cause warranty work to be refused if it can be shown to cause a failure.

 

According to the Magnuson-Moss Warranty Act of 1975, if you modify a vehicle, then any problems that result from that modification are not covered. They cannot void a warranty just based on the presence of aftermarket parts.
