Alright, so if you’re driving a Chevy or GMC truck or van from the late 90s or early 2000s with a 5.0L or 5.7L Vortec engine, and it’s been running rough, misfiring, or just guzzling gas, this RAYTEN FJ504 spider injector is probably what the doctor ordered.

It’s a direct replacement for that factory multiport injection setup, swapping out the old problematic design.

This bad boy comes with all the plastic, metal, and rubber bits you need—it’s a complete unit.

It fits a massive list of models: C1500, K1500, Suburbans, Tahoes, Yukons, Express and Savana vans, you name it, from 1996 through 2002.
The part numbers cross-reference to 89060440 and 21459618.

Plus, it’s backed by a lifetime warranty from RAYTEN.
So, if your truck’s been stumbling or throwing codes, grab this injector kit and get that Vortec purring like a kitten again.

It’s brand new, ready to bolt in, and should smooth out your idle and bring back some power.
