I think the ones I have off the shelf from Advance Auto work very well.

Can't confirm if they will hold up a loaded bike rack, but worth considering.� Price was
very reasonable too.

Subject: Rear hatch struts  - heavy duty
 
Hi All,
Bus Depot offers a set of heavy duty rear struts. They supposedly can hold open the hatch even with a bike rack and bikes.
Unfortunately they are on back order for 2-3 months.
Anyone know a alternate vendor?

Cheers,
Harry
