Question:

Hi, Im looking for replacement side rails for the frontrunner slimline ii rack. I see you sell the joiner kit that connects two side rails, but I cant seem to find the side rails themselves. Any help is appreciated.

Hi Kyle; are you looking for side rails like the Side Rail Expedition Kit for 85-1/4" Long Front Runner Slimline II Platform Racks # FR83VV? Assuming that is correct, how long is your platform? I went ahead and attached a link below with all of the available lengths for your reference.

Thanks for response, but what I'm actually looking for is the side pieces to the rack itself. These pieces are sold in the kits when you get a long version of the rack, and I'm looking to buy them separately to extend my short bed rack into a longer ladder rack.

@Kyle we don't have them on the site but I can see about adding them. However, there are various lengths. Do you know what length you're looking for?

@RobinH, that would be great! I would want the longest available (I think 1358mm, or #2 from the product manual).

@Kyle alright, I can work with that. Let me see what I can get from Front Runner and if it is something available for aftermarket sales. Since it is Sunday I'm sure it will take a few days to hear back from them and sort it out.
