Product Details

Monroe Strut-Mate is the brand’s replacement line for suspension service parts that support proper strut protection and fitment. Part number 63638 is a front strut boot kit for vehicles such as the 2013-2022 Buick Encore, 2013-2022 Chevrolet Trax, 2013-2017 Honda Accord, 2010-2019 Kia Soul, and 2003-2005 Honda Civic. It is also listed for many BMW front suspension applications, including 1992-2003 3 Series and 5 Series models with the specified suspension notes.

Use this Monroe 63638 boot kit when the original boot or jounce bumper is cracked, torn, or missing. The bellows help keep contaminants away from the strut shaft, while the bumper adds impact protection during suspension travel. For select Toyota Prius and Prius V applications, the fitment notes specify not to use the boot in the kit and to use Monroe part number 909931 or reuse the OE insulator.

What It Helps Solve

• Damaged or missing front strut boot
• Cracked jounce bumper on the strut assembly
• Exposure of the strut rod to road debris
• Premature wear from moisture and contamination
• Reduced protection after front suspension service
