KYB 234005 Suspension Strut - Rear

KYB Excel-G Rear Suspension Strut for Pontiac Fiero

The KYB Excel-G 234005 is a rear suspension strut for 1984-1987 Pontiac Fiero models. Built to restore original ride control and handling balance, it is a direct OE-style replacement for drivers who want factory-correct response from the suspension.

As part of the KYB Excel-G line, this strut is calibrated to return the vehicle’s designed control characteristics rather than alter them. It is a practical choice for a Pontiac Fiero rear strut replacement when consistent steering response, body control, and alignment stability matter.
