The 27-year old was set to become a restricted free agent later this year but will now remain an Eagle until the end of the 2023 season.
Cripps was thrilled to commit his future to West Coast.
“Obviously really exciting to hang around here for hopefully the rest of my career, so happy days,” the goalsneak told westcoasteagles.com.au.
“I just love the club, love WA. Stoked to stay in WA and I think the club is going in a good direction.
“Obviously we’ve got the new facilities here (at Mineral Resources Park), Optus (Stadium) and all that sort of thing, so the club is looking good.”
Heading into the 10th season of his carer, 163-gamer hopes to continue his development as a leader for the younger players to follow.
“I suppose the last couple of years my leadership on-field has probably changed a bit being one of the older half-forward players in the team,” Cripps said.
“I’ve got to help out the Jarrod Camerons and the (Jack) Petruccelles and the (Liam) ‘Flyin’ Ryans.
“I do like that role I’ve been playing and I’ll continue doing that over the next couple of years.
“We’ve got some speed, got young fellas coming through and we’ve still got the old heads of ‘JK’ and ‘JD’ as well.
“I think we’ve got a good mix and that’s shown over the last couple of years playing together.”
