How does the fiberglass top of a K5 hold up in a roll?

    Just wondering how well the fiberglass top on the rear of a non-full-convertable K5 holds up in a roll. I didn't know if it was reinforced or if it would just crush.

    from what i have heard, in a rollover the fiberglass tops tend to stay in one piece, the only downer is, that they ushally seperate from the rest of the vehicle. this really makes the rear seatbelts dangerous if they are strapped to the top

    Yeah. So do the bolts shear off or do they just rip the caged nuts out of the bed rails?

    They don't hold up well at all, here is a picture of my friends truck. The top didn't stay on or stay in 1 piece.

    It looks like it just ripped off the bolted down portions.

    They are crispy and crunchy. I made mine stronger with an interior layer of paper machea and an external layer of spray paint. This made it much stronger. And quieter. I'm not even scared of rolling..... Seriously, they don't do much from what i've seen. Somebody show that roll with the two guys on potato salad hill. Watch what happens to that blazer and then realize how lucky those guys are to have their skulls intact.

    It would make sense that it could hold if it rolled on something that spread the force out, like sand or soil. However, if it hits a rock or something that creates a pressure point, it will surely crack and then it's a sure thrashing.

    guess it depends on how many times you roll. I rolled my 78 3 1/2 time down a hill at TDS this year and it held up fine. and only one of the glass side broke out the other stayed in tact.

    Wow! I can't believe that it didn't do more damage to the top. It looks like the front of the truck took the majority of the roll but I still can't believe it didn't smash it to bits. Makes me feel a little bit better about not have a cage.

    yeah mine did not have a cage either. It was all factory. The main hoop even held up just fine.

    Yes, but it was discovered that those guys driving that truck did not have all of the bolts bolted down. With all of the bolts in, a flexy truck runs that chance of cracking the top at full flex (due to frame flex). I think it was discovered that the truck that rolled on potato salad hill only had 4 of the bolts in. :eek1:

    BTW- The fiberglass tops are reinforced with steel at the points that take the brunt of the impact in a roll. There are a ton of factors that will determine if the stock hardtop holds up to a roll. If it is a slow roll, then it should hold up pretty well. If it is a violent, multiple roll, then it might not be pretty. Hell, many interior cages need to be re-done after hard rolls.
