KYB KG9132 Suspension Strut - Rear

KYB Gas-a-Just Rear Strut for Mazda RX-7

The KYB Gas-a-Just KG9132 is a rear suspension strut built for 1986-1991 Mazda RX-7 applications. It uses a monotube design with separate gas and oil chambers to deliver responsive damping, stable control, and consistent ride quality during normal driving.

Key Features

• Monotube Gas-a-Just design with air-free hydraulic response and high-pressure nitrogen gas support
• Up to 25% more damping performance than original equipment shocks
• Engineered specifically for the Mazda RX-7 rear suspension
• Higher gas pressure improves steering response and control
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Fade-resistant operation from separated gas and oil chambers
• Supports vehicles with added load demands, towing use, or larger wheels and tires
• Compatible with electronic safety systems when suspension performance is maintained as designed

Detailed Description

KYB Gas-a-Just KG9132 is an OE-style monotube rear strut for the Mazda RX-7 that restores suspension response with firmer control than a standard twin-tube design. The internal floating piston separates the gas and oil, helping maintain consistent damping under changing road conditions. This part number, KG9132, is a direct-fit rear strut choice for 1986-1991 Mazda RX-7 models listed below, including applications noted as recommended OEM replacement and electronic suspension conversion use.

This part cross-references Monroe Shocks & Struts 71217 for the same application.

What It Helps Address

• Excessive bounce or poor body control from worn rear struts
• Reduced steering response caused by weak damping
• Fluid leakage related to seal wear on aging suspension components
• Fade during repeated suspension movement or heavier-duty use
• Loss of ride consistency on a Mazda RX-7 with original rear suspension wear
