Does anyone know if an injector off a 2011 Cadillac CTS-V would be a direct fit for a 2013 GMC 5.3L? I've called several places and get differing answers. I'm thinking I may need adapters for height and maybe the pigtails. If anyone has done this any help would be greatly appreciated! Asking because I went with ID1300 in Cadillac and going bigger injector in the truck for F/I.

They are shorter injectors, you need spacers to make them.

The injector connectors are the same though. They should all be USCAR connectors.

I really appreciate it!! Do you happen to know what size or have a link to the correct adapter?

I don't have a stock truck injector handy to measure the center to center distance to know the exact size. You may be able to look up the truck injector size or grab one of yours and measure.

Here is the LS3 type injector length.

Appreciate it! I'll have to look at the injector when I pull it unless someone else knows the size off the top of their head.

I used these injectors on my 07 4.8 turbo build they were too short. I used 14mm spacers from foreinnovations.
