These premium aftermarket replacement components are manufactured to meet your expectations for fit, form, and function. Review: AC Delco Professional is the way to fly - AC Delco Professional is the way to fly. The idler mount, arm, and pitman arm are only about $60 total more than the same parts in the ACDelco Advantage line, but the Professional line is much beefier. They work for the GMT 800 trucks. Strongly recommend the OTC 6496 Close Quarters Pitman Arm Puller for Truck/SUV, given the frame on these trucks; that puller is the best $60 your may ever spend. In addition to stopping the tire wear issues with the old idler and pitman arms, this made a huge difference in the ride quality of my truck at highway speeds! I used Mystik JT-6 Hi-Temp lithium-complex grease to lube them up, and all the ball joints and tie rods. It's a high temp grease for wheel bearings, but cheap and has killer specs (they do list it as a chassis grease). Review: 2005 Hummer H2 - Fit on 2005 Hummer H2. I initially went with the Moog but the Moog wouldn't fit in the mounting frame without modification. This fit perfectly. ## Features - Helps turn your vehicle’s wheels in reaction to your steering wheel - Coated with a corrosion resistant material - Sealed boot helps prevent contamination and maintains lubrication - Larger one-piece design for reduced wear and increased carrying capability ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000JZYWUK | | Best Sellers Rank | #529,805 in Automotive ( See Top 100 in Automotive ) #79 in Automotive Replacement Idler Arms | | Brand | ACDelco | | Customer Reviews | 4.4 4.4 out of 5 stars (384) | | Date First Available | October 10, 2007 | | Exterior | Machined | | Is Discontinued By Manufacturer | No | | Item Weight | 2.6 pounds | | Item model number | 45C1123 | | Manufacturer | ACDelco | | Manufacturer Part Number | 19136508 | | Model | Steering Linkage Idler Arm | | OEM Part Number | 19136508 | | Product Dimensions | 10.7 x 4 x 3 inches | ## Images ![Professional 45C1123 (19136508) Steering Linkage Idler Arm - Image 1](https://m.media-amazon.com/images/I/61vG8JfWG7L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ AC Delco Professional is the way to fly *by V***Y on April 5, 2018* AC Delco Professional is the way to fly.

I initially went with the Moog but the Moog wouldn't fit in the mounting frame without modification. This fit perfectly. ### ⭐⭐⭐⭐⭐ Quality and perfect fit *by Z***S on December 16, 2020* Seems to be a solid well built part which should last a while - I made the mistake of buying cheaper front end kit made by Detroit diesel which lasted less than 5k miles ! Should have purchased the oem quality the first time around and saved myself twice the headache of replacing these parts !
