Confirmed: Left and Right Are Genuinely Separate Parts

Genuinely worth knowing: Toyota's own parts catalogue lists left and right rear shock absorbers as distinct, non-interchangeable references — not a single part fitted to either side. Confirm which side you need before ordering.

Toyota GT86 Rear Shock Absorber: The Part That Takes Every Bump Before You Feel It

On the Toyota GT86, most attention (and most complaints) go to the front suspension because of its role in steering, yet the rear shocks wear on a similar timeline — just more quietly, easy to write off as road noise until it's obviously gotten worse.

Before you buy: engine, trim, and left/right side all affect fitment. Always confirm against your VIN before ordering.

OEM Part Number: confirm via VIN — rear shock absorbers (aftermarket) Bilstein B6 Performance 24-228398 / Bilstein B8 Performance Plus 24-228435

Accuracy note: Covers the Toyota GT86 (2012-) as listed in the UK aftermarket catalogues. Rear shock absorbers are replaced as a pair across the axle, because a new damper beside a worn one leaves the car feeling uneven. The right one depends on the engine, the suspension type (standard, sport or heavy-duty, and electronic damping on some models) and sometimes the body style. The references below are UK aftermarket catalogue listings for this generation, labelled by brand with the fitment details the catalogue gives; carmakers rarely publish the genuine number against these, so match a genuine damper against your VIN if you want a guaranteed fit. genuinely worth knowing: Toyota's own parts catalogue sometimes distinguishes rear shocks by build location (Japan-built vs local-built) in addition to engine/trim — an extra variable worth checking against your specific VIN.

Rear shock absorbers (aftermarket)	Bilstein B6 Performance 24-228398 (gas); Bilstein B8 Performance Plus 24-228435 (gas, sport); Koni Sport 8041-1416SPORT (gas)
Genuine (OE) numbers quoted	None quoted in the catalogue listings — the genuine damper varies by engine, suspension type and body style, so order it against your VIN
Standard trims, right	Genuinely a different part number from the left-side shock — confirm side before ordering
Standard trims, left	A genuinely different reference from the right-side shock above
Sport-trim shock, where fitted	A genuinely different, stiffer shock from standard trims

Best practice on the Toyota GT86 is to change shock absorbers as a pair, even if only one side is visibly the problem, to keep damping matched side to side.

Toyota GT86 Rear Shock Absorber: What It Does

Working independently of the coil spring, the Toyota GT86's rear shock absorber determines how quickly the suspension settles after a bump. A worn unit lets the back of the car bounce for longer than it should.
