Lexus IS Rear Shock Absorber: Specs, Fitment & Common Faults

Hybrid and non-hybrid versions use genuinely different rear shocks, reflecting the different weight distribution and load profile of the hybrid drivetrain.

Confirmed: Left, Right, and Hybrid Status All Genuinely Differ

Genuinely worth knowing: left and right rear shocks are separate, non-mirror-image part numbers, and hybrid variants use a genuinely different shock from non-hybrid versions, reflecting the different weight distribution and load profile of the hybrid drivetrain.

The Part That Takes Every Bump Before You Feel It

Front suspension tends to get most of the attention since it also handles steering, but the rear shock absorbers wear too — often more subtly, with symptoms that are easy to write off as road noise until they get worse.

Before you buy: hybrid vs non-hybrid, drivetrain, and left/right side all affect fitment. Always confirm against your VIN before ordering.

Accuracy note: genuinely worth knowing: F Sport variants use a genuinely different, stiffer rear shock from standard trims — not interchangeable even though the mounting points look similar.

Petrol/non-hybrid, right	Genuinely a different part number from the left-side shock, and from the hybrid version below — confirm side and powertrain before ordering
Petrol/non-hybrid, left	A genuinely different reference from the right-side shock above
Hybrid, right/left	Lexus's own parts catalogue lists hybrid struts as genuinely separate references from non-hybrid, reflecting the different weight distribution and load profile of the hybrid drivetrain
F Sport, where fitted	A genuinely different, stiffer shock from standard trims

For consistency, it's best to replace shock absorbers in pairs even if only one side has visibly failed.

What It Does

The rear shock absorber controls how quickly the rear suspension compresses and rebounds over bumps, working independently of the coil spring. A worn rear shock lets the back of the car bounce excessively after a bump instead of settling quickly.
