Product Details

KYB Excel-G is built on the same OE assembly lines used for KYB original equipment products and is calibrated to return the vehicle to its intended performance balance rather than change it. For drivers searching for a front strut cartridge for 1988-1994 BMW 750iL, 1993-1994 BMW 740iL, or 1988-1990 BMW 735i front suspension service, this part provides an OE-style replacement solution. It also serves 1988-1990 BMW 735iL, 1988-1990 BMW 535i, and 1989-1990 BMW 525i front applications with the correct suspension configuration. This part cross-references Monroe Shocks & Struts 73308 for the same application.

What It Helps Address

• Excessive front-end bounce or float
• Reduced steering precision during lane changes
• Uneven tire contact caused by worn damping
• Brake dive and unstable stopping feel
• Noise or vibration from worn suspension control components

Installation Notes and Tips

Verify the vehicle’s suspension type before ordering, since some BMW applications are excluded for self-leveling, electronic suspension, electronic adjustable suspension, or M-Technik setups. This cartridge has a compressed length of 20.79, an extended length of 27.87, a stroke length of 17.64, and a 12x1.25 upper mount type. KYB recommends replacing the strut mount, part number SM5053, and protecting the assembly with strut boot SB105 to help reduce noise, vibration, and contamination.
