Dorman Turbocharger Unison Ring
Dorman Turbocharger Unison Rings: Precision Replacements for Variable-Geometry Turbos
A variable-geometry turbocharger is one of the most sophisticated components in a modern diesel or turbocharged engine — and the unison ring is the mechanical heart of that system. Turbocharger unison rings move the turbo's vanes in the exhaust housing to decrease or increase speed, enabling the turbocharger to optimize boost pressure across a wide RPM range. When this ring corrodes, wears, or seizes — a common failure point on high-mileage trucks — the result can be sluggish throttle response, black smoke, limp mode, or complete loss of variable boost control. That's where Dorman steps in with a purpose-built replacement solution.
Dorman OE Solutions: Engineered to Outlast the Original
Dorman's turbocharger unison ring falls under its trusted OE Solutions product line, part number 904-267. Innovative Dorman OE FIX upgraded designs offer a better turbo repair solution than the factory parts. Rather than simply reproducing a part known to fail, Dorman's engineering team examines the root causes of original equipment failures — most often corrosion and wear — and builds the replacement to resist those exact conditions.
The OE Solutions Stainless Steel Turbocharger Unison Ring is backed by a team of product experts in the United States and more than a century of automotive experience. These rings are constructed from steel materials, have been tried on vehicles for specific fit, and have been corrosion-tested for quality standards. That corrosion resistance is especially critical given the extreme heat cycling and exhaust-side exposure that unison rings endure in service.
Fit, Function, and Compatibility
This turbocharger unison ring is designed to match the fit and function of the original ring on specified vehicles, and is engineered for durability. Compatible applications include select Chevrolet (2006–2007), Ford (2005–2010), and GMC (2006–2007) turbocharged models — vehicles whose factory VGT turbos are notorious for unison ring-related failures. It restores functionality as a reliable replacement for an original part that has failed due to corrosion and wear.
Dorman's deep catalog in the turbocharger space doesn't stop at unison rings. Their diverse inventory covers direct replacements for failure-prone turbocharger system parts, with more than 100 direct-replacement parts including feed/return lines, clamps, oil lines, and more, covering 80+ million repair opportunities on popular turbocharged vehicles.
