Dorman 949-836 Suspension Shock Absorber - Rear Right

OE Fix Magnetic Ride Shock for Cadillac XTS

Dorman 949-836 is a rear right suspension shock absorber for select 2013-2019 Cadillac XTS models with RPO code F55 magnetic dampening. It addresses a common OE failure point in the original rear strut design by using an upgraded top seal block assembly and more durable mounting points.

This Dorman OE FIX shock absorber is built for drivers looking for a direct replacement for the rear right position on Cadillac XTS vehicles with Continuously Variable Real Time Magnetic Dampening. Part number 949-836 is engineered to restore damping control after seal wear, fluid leakage, or loss of suspension response.

How It Restores Suspension Performance

On Cadillac XTS rear suspension systems equipped with magnetic ride control, seal deterioration can lead to fluid loss, reduced damping, and a noticeable decline in ride quality. Dorman 949-836 uses an updated seal block design that better manages internal fluid pressure during compression and rebound cycles, helping address the failure mode commonly seen in the original equipment unit. This part cross-references Arnott Industries MR-4359 and SK-3357 for the same application.

Common Problems It Can Solve

• Rear suspension fluid leakage from a worn top seal assembly
• Excessive bounce or reduced damping at the rear right corner
• Loss of magnetic ride control response
• Ride instability caused by a failing OE rear strut
• Inspection issues related to a worn or leaking shock absorber

Installation Notes

Fits 2013-2019 Cadillac XTS, rear right, w/RPO Code F55 (Continuously Variable Real Time Magnetic Dampening). Verify the vehicle’s RPO code and mounting style before installation. Mounting hardware is not listed as included, so reuse or source the required hardware as needed. Confirm the upper thru-hole and lower bushed eyelet mounting points match the original unit.

Quality Assurance

Dorman 949-836 is a standard replacement shock absorber with an OE FIX design that targets a known failure point in the factory rear strut assembly. It is built with upgraded mounting points and a revised seal block assembly for improved durability in demanding suspension service.
