They are designed to be super strong and encapsulate the shock - no more bent shock screws. This is very important with all the new stronger shocks entering the market. This mount still uses the tried and proven 4-point mounting system that has been so successful with our Phatdaddy and Skinnydaddy mounts.
The TR front HD is compatible with the stock and most aftermarket towers, it is NOT compatible with the RAMTech #9110 (Front suspension set), or any carbon fiber tower with adjusted suspension height. It IS compatible with RAMTech #9104 (standard billet shock tower).
