💡 What determines the correct lifting capacity for a heavy tailgate or tonneau cover assembly?
Picking the right gas spring keeps your panel from dropping unexpectedly while making swaps handy during daily hauling. Here is how to size yours without a headache:
- Measure your load weight first since two hundred to two hundred seventy five pounds falls neatly inside a three hundred pound class tube
- Check the pivot point distance because longer throws demand higher piston force to balance the torque curve
- Look for sealed bearing designs that handle outdoor exposure without leaking nitrogen pressure
- Verify bolt hole spacing stays compatible with your existing bracket layout to avoid custom drilling work
