The Hendrickson R520 bushing, part number 45503-7 or 455037, is a direct-fit suspension bushing for Hendrickson R520 series suspension systems. Bushings in this position absorb road shock and control axle movement, making correct fitment critical to suspension geometry and component longevity. This is a genuine Hendrickson part sold by Pro Gear and Transmission. If you are working from a bill of materials or cross-referencing against an existing part, the number appears in both formats: 45503-7 and 455037.
