TJM Products bull bars will accept only low mount winches. Winches with an integrated solenoid will not fit within the bumper channel.
Most steel bull bars are designed to have a winch fitted directly to the bull bar, and do not require winch frames. The steel bull bars that do require winch frames are called "recessed roller" bars. This type of bull bar is a special design required for airbag compatibility on some vehicles.
All Aluminum bull bars require a steel winch frame to support a winch.
All winch capable bull bars fit up to a 9000 lb low mount Warn or Ramsey electric winch. Some bull bars such as the Ford Super Duty bull bar can accept a larger winch. Call your TJM Distributor to inquire if a larger winch will fit in the desired bull bar.
I ordered a 9.5XP and TJM winch mount kit...as far as I could determine the 9.5XP was the largest winch that would fit (will need to relocate the solenoid into the engine bay) and wouldn't stress the bumper and/or winch mounting plate too much. It is supposed to arrive later this week...but I won't have time to install until next week...I will post up as soon as I know something more about the fitment.
