4.88s are great if you have a stick, with the auto you need all the gear you can get. My axles came 5.13 and with 35s they were great. With 37s I'm in 3rd gear all the time on the highway. This would be a similar situation for you with 35s and 4.88s, don't settle till you find a shop that will install the gears with a warranty.
By the way its been my experience that most gear manufacturers don't honor warranties, they just blame any failure on setup regardless of the facts. So if you get a parts and labour warranty chances are the shop is eating the cost of the second set of gears.

There must have been a time
when we could have said no.
Regardless, they still offer a 2 year warranty on the 5.13. I can't recall a gear set that went broke due to improper manufacture. We had some that were noisy no matter of set up, most likely due to improper lapping from the factory.
