Installing JT Strongarm Stabilizer on a 16 Grand Design Reflections 337RLS 5th Wheel w/4 pt Leveling  


I want to install a JT strong arm stabilizer system but there is no documentation on how you install on the rear hydraulic rams. Will this system work with my LCI level up system 2016 Grand Design Reflections 337RLS fifth wheel with 4 point leaving


Expert Reply:

Yes, the JT Strong Arm Stabilizer System # LC191023 will work with your LCI Level Up System.

I checked with Lippert and found that you can use the JT's Strong Arm Jack Stabilizer Kit # LC191023 with the adapter lugs # LC314592. For your LCI level up system will need a quantity of 6 adapter lugs, these are sold as a quantity of 2 on our site. The manufacture also provided me with instructions I will be sending you in a separate email.

I have linked the adapter lugs to this page for your convenience.

Can the JT Strongarm stabilizers be used on a grand design 303 2019? Can you send directions if so? Thanks

As long as you have more than 58" of space between the front landing gear legs on your Grand Design trailer, the JT's Strong Arm Jack Stabilizer # LC191023 will work great. We don't have install instructions specific for your trailer, but the primary manual is attached on the product page.
