Suspension upgrades regarding warranty?

I am going to put 5100s (set at 0") + eibach coils and 5100s in the rear on my 2013 DCSB 4x4 TRD OR...But don't want to void my 7/100k extended warranty that I purchased for my Toyota Cetified truck. I know they won't warranty the non-OE parts, but I don't want to open a can of worms.

In order to not have toyota void my warranty should I,

-Have the dealer do the work? (Would like to avoid this expensive labor)

-If not the dealer, would having my independent mechanic be a problem?

-Or if this poses no warranty issue at all I may just do it myself.

 

They can't deny the warranty unless they can prove the part you swapped in was the direct cause of the problem.

Install it yourself if you have the tools and a friend to help. Might just cost you a pizza or two and some beverages
