Are there better lift gate supports an the OEM ones? Tailgate won't remain up. on 1994 Ford Aerostar

I've replaced my lift gate hydrolics twice now, and both times they were not strong enough to deal with the weight of the lift gate. Is there any company out there that makes a stronger version that will accomodate how heavy this gate is?

The aftermarket ones lots of times come in different weight handling ratios. If you are getting the wrong ratio it explains why you are having probs. Best may be from dealer if you have to drive all over trying to find correct ones from aftermarket and burn up fuel in the process.
