Product Details

KYB Excel-G is the brand’s OE replacement line for drivers who want factory-correct suspension behavior rather than a changed ride feel. Part number 3340052 is calibrated to restore the designed control of the Subaru Forester, Subaru Crosstrek, and Subaru XV Crosstrek, using OE-quality components and KYB’s original-equipment manufacturing approach. This part cross-references Monroe Shocks & Struts 73071 for the same application.

Dimensions include a compressed length of 15.39 inches, extended length of 20.02 inches, and stroke length of 4.63 inches. The upper mount type is 12X1.25. KYB also notes that electronic safety systems depend on suspension, brakes, and tires working as engineered, so maintaining proper strut performance supports those systems as well.

What This Strut Helps Address

• Excessive bounce or poor damping after suspension wear
• Loose steering feel or delayed lane-change response
• Reduced stability during braking and cornering
• Uneven tire contact caused by weakened strut control
• Noise or vibration related to worn front suspension components

Installation Notes

For the 2016-2017 Subaru Crosstrek and 2014-2015 Subaru XV Crosstrek, replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. KYB recommends new strut mounts, part number SM5664, to reduce noise and vibration, and a KYB strut boot, part number SB101, to help protect the strut from dirt, debris, and salt.

Quality Assurance

KYB is a major OE supplier, and Excel-G is produced on KYB OE assembly lines using OE-quality components. The line is engineered to return the vehicle to original designed performance and is classified by KYB as Original Equipment for the Aftermarket (OEA).
