Extender Side Arms let the Hydraulic Assist Cover Lifter span the Summit XL’s extra-long cover. The Summit XL’s footprint is longer than the standard lifter arms are built for — these extended arms make up the difference so the lifter pivots the bigger cover cleanly.
Required for: any Hydraulic Assist Cover Lifter installed on a Summit XL. Not needed for other models — the standard arms handle the rest of the lineup.
