Review on High-performance Starter Solenoid - Victory Lap 66-132 by Corey Listner

Fits? That's the big question I had. Well I took a chance and it fit my 1996 K1500 Suburban Transmission. If you have a direct drive starter this magnet is too small. It's easy to tell what you look like. Just measure the diameter of the starter (after disconnecting the battery negative terminal of course). If the starter housing is about 3 inches (75mm) in diameter, it is a PMGR (Permanent Magnet Gear) starter. If it's much larger then it's direct drive and that magnet won't work. The PMGR starter solenoid valve is approximately 50 mm (2 inches) long. In diameter. The end of the plunger is plastic. The old one is also made of plastic. This is probably necessary to prevent a short circuit. Time will tell if the plastic used in this solenoid will stand the test of time. The old man showed no signs of weakness. To remove the magneto from the starter (I did this when the starter was removed from the truck) you will need an E6 torx socket to remove and re-tighten the screws. You don't need to loosen the 2 screws that hold the heat shield in place, but you do need to loosen the remaining 3. Make sure the new solenoid is aligned in the same orientation as the old one. The smaller bolt will be away from the starter. My solenoid comes with a paper gasket to keep out water and oil. The old one didn't have a pad, but I put it on anyway. I also added an extra nut to prevent the struts from being overtightened, so I needed a magnet to start with because I broke the old one. I bought a pack of Lowes M8x1.25 nuts and installed (loosely) one per bolt with a dab of metallic anti-seize grease. I then installed the electrical wires and then put on the supplied nut with additional anti-seize coating. I then used two 13mm wrenches, one to hold the inner nut to protect the solenoid from damage and the other to tighten the outer nut. It feels tight and solid and the truck starts great. This adjustment will hopefully prevent corrosion preventing the chain from working in the future and will prevent the nuts from loosening. Overall it was easier than a similar job on a Toyota of the same year and for about the same price. This is well within the power of a person wishing to change their own launcher.
