willl this work for a 2012 chevrolet silverado lt 5.3? thanks

It looks like a 2012 did come with Active Fuel Management system. The Range will work on it. If you have further questions Range is great at answering questions.

Will this work on a gmc 2019 pickup denali 6.2 engine

Yes, it should work fine. Thank you.

Will this work on a 2019 suburban 5.3?

I believe it should, works on a 2018 5.3 silverado.

Would this work on my 92 oldsmobile?

I don’t believe Active Fuel Management was available in ‘92. So, I would say no. But check the product page on the Range website for compatibility just to be sure.

Recommend to others

So far works great. Had purchased same type of product from another manufacturer and that one had warning lights go on where there were no issues. This one is awesome. Worth the money

Range Tech disabler

This is an excellent plug and play module to save your engine. Simply insert into your OBD and leave it in. Don't buy the cheap ones. Works as it should. No more cylinder shut down or engine stop/starting. Highly recommend. Bought it for my 2021 Chevy Blazer

Expensive, but does its Job

Works as intended, using it in a 2018 Camaro SS

Range RA003B, excellent product

I am in Australia. Ordered through Amazon. I read as many reviews I could find. Used in the Chev 1500 Silverado for a week or so and found it to be as advertised. Can't fault it at this time.
