"I bought these since I was installing heavy duty leaf springs on my 2018 Nissan Frontier. I know that the rubber bushings always end up rotting away and I wanted a bushing that I could use with the new greaseable shackles I was also installing. The fit was perfect and they work excellent with the shackles."
"Customer service wasn't good, this didn't fit as described, even called before ordering making sure it would work. Does not work with oem springs."
"I ordered it with a greaseable shackles and the installation works perfect on my old man emu medium heavy leaf springs on my 2018 Nissan Frontier 4x4. Thank you for a quick shipping and customer support! I painted the shackles to prevent from getting rusty while I drive on heavy forest roads. . . the ride is so much smoother and easier."
"Front bushings slightly loose fit."
"Great product"
"Iornman H. D. leaf springs and bushings installed, perfect fit 👌. Can't wait to put to the test off road!!"
"These bushings are not universal in size. Meaning, they will not work with factory shackles or aftermarket shackles. They are only designed to fit Iron Man shackles. I had to make new sleeves for the correct diameter of these bushings. More of a headache than it's worth. ."
"These bushings paired with Ironman's greaseable shackles made my Xterra ride a lot smoother and now they don't squeak. They're definitely an important upgrade."
"Fit perfectly"
"These polyurethane spring bushings are a significant upgrade form the OEM rubber bushings, and are a direct replacement fit."
IRONMAN 4X4 Polyurethane Bushings feature a unique high density injection molded polyurethane material, providing precise location and a durable bearing surface for your leaf springs, making them very durable in hot temperatures whilst providing soft comfortable vehicle ride.
All Ironman spring bushings also feature the special spiral and flange grooves - incorporated grooves and spiral bore rifle - to distribute lubricating grease evenly throughout the bushing surface when combined with greasable shackles and pins.
