They sell just the "struts" good for up to 300 lbs weight.....that should more than do. I have tried several Hyundai Parts sources trying to find the exact specs on our OEMs to NO avail. Could easily do
the necessary measuring of the strut [necessary for order] but I myself would be unable to guesstamate the diameter of the most important ends with the threads.
I did find the OEM replacement struts for $27-28 though. I also emailed Redline....have NOT heard back.
