Gabriel G57587 Ultra ReadyMount Rear Right Strut Assembly for 06 Lexus

In this review of the Gabriel Ultra ReadyMount complete strut assembly the bottom line is simple: this preassembled rear right unit is ideal for DIYers and independent shops replacing a worn rear strut on a 2006 Lexus RX400h FWD because it saves time and removes the need for spring compression. The reviewer found the assembly straightforward to fit, with components like the upper mount, boot, bumper and coil spring already installed, so the most compelling reason to buy is the time and safety benefit of a factory-like, ready-to-install unit.

Key Features

• Preassembled ReadyMount: Arrives with the upper mount, strut bumper and boot fitted so installation skips spring compression and is quicker for a single mechanic or DIYer.
• Complete components: Includes the coil spring and spring seat with an Ultra strut to restore original suspension geometry and ride control.
• Direct fitment: Built to fit the 06 Lexus RX400h FWD so it matches the vehicle's existing mounting interfaces and reduces alignment surprises.
• Durable construction: Gabriel designs the Ultra strut with corrosion resistance and materials intended for long term service on passenger vehicles.
• Labor saving: With a collapsed length of 16.81 in and extended length of 24.33 in the assembly is shipped ready to mount and should cut shop hours for rear replacement jobs.

Who It's For

This Gabriel ReadyMount is aimed at owners of a 2006 Lexus RX400h FWD who want a like-for-like rear right strut replacement without dealing with spring compressors or chasing individual parts. It's a practical choice for experienced DIYers, mobile mechanics, and independent shops that value time savings and consistent component fit.

It is less appropriate for someone who needs a custom valving change or performance-tuned setup, since this is an OE-style replacement focused on convenience and correct fit. Those seeking upgraded sport damping or nonstandard ride height should look at performance coilovers or revalved units instead.
