Housing Cap
Our housing cap is carefully crafted with CNC billeted aluminum for longer-lasting durability and reliability.Your standard plastic cap would be easily cracked when over tightened or long term used,and it is difficult to use a wrench to install/remove.You can simply remove your old cap and screw your new cap on its place using a 1" socket wrench.
