Detailed Description

This Dorman OE FIX magnetic strut is engineered for 2015-2020 Cadillac Escalade and Escalade ESV, 2015-2020 Chevrolet Tahoe, 2015-2020 GMC Yukon and Yukon XL, plus 2015-2018 Chevrolet Silverado 1500 and GMC Sierra/Sierra 1500 applications with Z95 MagneRide suspension. It also fits 2019 Chevrolet Silverado 1500 LD and 2019 GMC Sierra 1500 Limited front suspension setups with the same option code. The design focuses on the seal assembly, where original equipment units commonly fail from heat, friction, and fluid pressure during repeated compression and rebound cycles. Part number 949-700XD is a practical replacement when restoring damping control on these vehicles.

This part cross-references GM 23151123 and Monroe Shocks & Struts 172286 for the same application.

What It Helps Solve

• Front strut fluid leaks caused by seal wear
