CURT TruTrack 4P Weight Distribution Hitch 10,000 lb — Integrated Sway Control, Hardened Trunnion Bars

The CURT 17500 TruTrack 4P is a 10,000 lb-rated weight distribution hitch that combines precise load spreading with built-in active sway control for more stable towing.

The TruTrack 4P blends weight-distribution technology and integrated sway resistance into a single assembly engineered for heavy trailers like campers, livestock rigs, and car haulers. Instead of relying on separate sway bars or friction-only devices, this system uses hardened trunnion-style spring bars, a spring-and-cam mechanism, and adjustable support brackets to transfer tongue weight across all axles while reducing lateral movement.

How does the TruTrack 4P reduce trailer sway while towing?

The TruTrack integrates sway-control arms into the hitch head so lateral motion is actively resisted rather than left to add-on components. Its spring-and-cam arrangement builds counterpressure when yaw begins, then eases during turns for smoother handling.

• Four-point sway geometry keeps the trailer tracking straight under crosswinds and passing vehicles.
• Integrated arms prevent the spring bars from angling side-to-side like chain-style systems.
• Hardened internal parts maintain consistent damping over long service life.

What makes setup and adjustment simpler than other weight-distribution hitches?

TruTrack replaces guesswork and partial disassembly with accessible interlocking nuts and six preset tilt holes that let you set head angle quickly and repeatably. Adjustments are made from the outside of the head, eliminating the need to remove components during tuning.

• Six preset holes provide exact tilt options without measuring spacers or counting washers.
• Interlocking nuts are externally reachable for fast fine-tuning at the hitch site.
• Adjustable support brackets secure spring bars vertically and laterally for consistent geometry.

Which components help the TruTrack last longer under heavy use?

Durable materials and a robust mechanical design reduce wear compared with friction-only sway devices. The head is welded with cast elements and the system uses forged steel trunnion-style spring bars plus hardened cams and springs to resist fatigue over time.

• Forged spring bars provide reliable leverage and load transfer across trailer and tow vehicle axles.
• Hardened cam and spring internals maintain performance under repeated sway cycles.
• Welded head and cast parts increase structural integrity in demanding towing conditions.

Who this is for: The CURT 17500 TruTrack 4P is designed for owners of medium to heavy trailers who need a 10,000 lb-rated weight distribution system that also actively controls sway. It suits RV owners, horse and livestock trailer operators, auto haulers, and anyone who tows frequently and wants quicker setup, stronger components, and integrated lateral control without separate sway attachments.
