Blue Ox BXW4005 SwayPro Spring Bars - 550 lb Capacity Weight Distribution Kit

The Blue Ox BXW4005 SwayPro Spring Bars are replacement weight distribution bars designed specifically for Blue Ox SwayPro weight distribution hitch systems. These spring bars are rated for 550 pounds of tongue weight capacity and sold as a pair.

Key Features:

• 550 lb tongue weight capacity per pair
• Direct replacement for Blue Ox SwayPro weight distribution systems
• Heavy-duty spring steel construction for reliable load transfer
• Integrated sway control design works with SwayPro friction pads
• Sold as a pair (two spring bars included)

These spring bars work by transferring tongue weight from the rear axle of the tow vehicle forward to the front axle and backward to the trailer axles, improving steering control, braking performance, and overall towing stability. The SwayPro design incorporates built-in sway control functionality when used with the appropriate friction pad brackets.

Replacement spring bars may be needed when upgrading to a heavier trailer, after wear from extensive use, or if the original bars become damaged. Always match the spring bar capacity to your actual tongue weight requirements.
