Idler Support Brace, Weld-In Gusset, Duramax | 2001-2010

Idler Support Brace, Weld-In Gusset, Duramax | 2001-2010

The Merchant Automotive Idler Support Brace is a weld-in gusset that reinforces the factory idler support bracket tabs on the passenger-side frame rail of 2001-2010 Chevrolet Silverado and GMC Sierra 2500HD and 3500 trucks. Those stock tabs flex when turning and are notorious for twisting or tearing away from the frame. Once they move, the passenger side of the steering linkage sits out of position, the passenger tie rod runs at the wrong angle, and the steering gets loose and wanders. Welding in this brace stiffens the tabs and greatly reduces flex for a more stable steering system.

Key Features

• Weld-in gusset for the idler support frame tabs
• Made for Merchant Automotive and bagged in-house
• Reinforces the stock tabs against twisting and tearing
• Sold individually; one required per truck

Benefits

When the idler tabs flex, steering play shows up as wander, tracking in ruts and extra tie rod and tire wear. A new idler arm won't fix play that comes from bent or torn tabs. Reinforcing the tabs gives the idler support a solid mount so the steering linkage stays where it belongs. It's a good time to add the brace whenever the idler arm or idler support is being replaced, and it's especially worthwhile on trucks running larger tires or heavier tie rods, center links and center link braces. Replace if worn or damaged.

Frequently Asked Questions
