Good Stuff.
We have had a couple shipping issues, but each time they made it right and we ended up getting what we need. Quality parts at half the price of OEM. -
I almost want to cry ;( writing this review because I dont want people to find out about them and rather keep them in my pocket but they deserve it…
This company is great with Quality Products at amazing prices! Sometimes, their website is not the most accurate but is user friendly and if you got questions they will call back and are very prompt in responding via a call or text to verify inventory before placing an order.
I really appreciate and look forward to continuing to work with you all especially Anthony — he is amazing & the best!!!

How do I install the 5I7935 component?
To install the 5I7935 properly, prepare the area first and confirm the result afterward. Use these steps:

Which Caterpillar machines is the 5I7935 compatible with?
Compatibility for the 5I7935 component varies by machine and configuration, so cross-check it for your Caterpillar equipment before ordering. Check your manual or reach out to Propel Parts for help verifying fitment.
Does the 5I7935 component meet performance standards?
Yes. The 5I7935 is engineered to meet OEM specifications for material, dimensions, and durability. When replacing, choose genuine or high-quality aftermarket parts that meet or exceed OEM specifications so the part performs the way it was designed to.
How often should the 5I7935 be replaced?
The 5I7935 is typically renewed during scheduled service or a related repair. In demanding, high-hour operation, inspect it more often to stay ahead of wear. When servicing this area, the 5M3062 Bolt is commonly replaced at the same time.

A worn 5I7935 usually gives early warning through the assembly it supports. Watch for these signs:

- Reduced performance or reliability in the assembly
- Unusual noise, movement, or leaks near the part
- Premature wear on the components around it
Why is the 5I7935 component important, and what related part is commonly replaced with it?
A sound 5I7935 is inexpensive insurance against larger repairs. Servicing it on time with parts that meet OEM specifications keeps the whole assembly working as intended. During an overhaul, the 5J0964 Seal U Cup is frequently replaced alongside this part.
