Synergy Manufacturing Steering Box Brace — 2009–2025 Ram 2500 / 3500 — 8559-04

Synergy Manufacturing sector shaft steering box brace in 2.0 in square tube for the 2009–2025 Ram 2500 / 3500.

Steering wander on a solid-axle heavy-duty truck comes from accumulated slop — worn joints, a tired box, a track bar that no longer locates the axle. Left alone it eventually produces death wobble, the violent self-sustaining shake that takes both hands and a lower speed to stop.

On a Ram HD one of the most common sources is play in the sector shaft where the pitman arm attaches — the steering box is bolted to the frame on one side only, and the shaft end has nothing supporting it.

This brace installs between the frame rails and the factory front sway bar, effectively adding a crossmember that the steering box now also attaches to. The sector shaft gets supported at both ends instead of one.

It is built from 2.0 in × 0.120 in wall square tubing in a gloss black powder coat, and it is about the quickest and cheapest worthwhile upgrade available for the front end of these trucks.
