I'll admit that I was skeptical of propel parts, but they are an honest site and came through with the order. I was skeptical because I've never ordered heavy machinery parts, and didn't know who to trust. The parts that I ordered showed in stock, but after checking with their vendor, they only had half of the order in stock. I was notified the day after the order, and most of the parts arrived in a few days. There was one part that was not shipped putz but I was able to talk with who I assumed is the owner who rectified the situation and had the part overnighted to me.
I will say that communication speed could use a little work, but they will eventually get back with you.
Frequently Asked Questions
What is the 2J3506 nut used for in Caterpillar equipment?
The 2J3506 nut is a heavy-duty fastening component used in Caterpillar machinery to secure bolts and studs in engines, structural assemblies, and mechanical systems. It helps maintain tight and reliable connections, preventing loosening under vibration or heavy load conditions, which is essential for safe and efficient equipment operation.
Which Caterpillar machines use the 2J3506 nut?

Contact Propel Parts if you need help verifying fitment.
