careful what you back into with those heavy duty wheelie bars. i have one myself but a little different design and i reversed into a object that wasnt going anywhere...and the screws where the wheelie bar attaches to, ripped out whatever the screws were attached to. in my case, the rear skidplate and the rear bulkheads in my 3905. because its not plastic, so it wont flex or bend.
very nice wheelie bar indeed.
