Frequently Asked Questions (FAQs)
Q: Does this bushing fit standard 3,500 lb. or 7,000 lb. trailer axles?
A: No. This is an oversized, heavy-duty commercial bushing measuring 1-3/4" on the outside diameter. Standard 3.5K to 7K axles typically use smaller 9/16" or 5/8" ID nylon or rubber bushings. Always measure your spring eye housing before ordering.
Q: Do I need a press to install this rubber and steel bushing?
A: Yes. Because it requires a secure, tight fit to prevent shifting during transit, a mechanical shop press or a heavy-duty bushing installation tool is highly recommended to properly seat the 1-3/4" OD rubber casing into the leaf spring eye.
Q: Is the steel inner sleeve removable?
A: No, the plated steel sleeve is chemically bonded directly to the nitrile rubber housing to ensure superior vibration dampening, noise reduction, and long-term durability without slipping loose.
