The JT Strong Arm Stabilizer System is a locking bracket system designed to reduce chassis movement in travel trailers and fifth wheels. This system utilizes a triangulation method, attaching to the coach’s landing gear or jacks. The documentation details installation procedures, operational notes, and required resources. It is crucial to unlock the Strong Arms before retracting the jacks when used with an automatic leveling system. The system is available in different lengths to accommodate varying distances between front jacks.
System Overview and Components
The JT Strong Arm Stabilizer System aims to provide stability to recreational vehicles. The system employs a bracket-based approach to minimize chassis movement during use. The documentation lists parts, including Jack Stabilizers for fifth wheels, available in lengths designed for spacing of 58 inches or less between front jacks (P/N 191023) and greater than 58 inches (P/N 191024).
Installation Procedure
The installation process requires specific preparation and a series of steps. Prior to beginning, it is essential to park the trailer on solid, level ground and clear any debris from the jack landing locations. The following steps are outlined in the provided documentation:
- Measure the inside distance between the front electric leveling jacks, just below the frame of the chassis.
- Mark the bottom of the cross-member centered between the front electric jacks, 1/4” from the front edge of the compartment. Mark the center of one of the pads.
- Remove a tap or bolt and secure the spacer mount. A 3/8” washer and a 3/8” - 16 x 1” self-tapping bolt should be used, ensuring grease is applied to the washer placed on the outside of the clevis, over the swing bolt.
- Secure a stiffening pad to the bottom of the main rail.
- Tap the 5/16” holes with either a 3/8” - 16 tap or a 3/8” - flange using a 3/8” - 16 x 1 1/4” swing bolt, a 3/8” washer, and a 3/8” - 16 x 1” bolt.
- Reassemble stabilizer tubes with the inner tube sticking out past the end of the outer tube by 5”. Tighten the nut until the stabilizer tubes swing with resistance.
- Insert a 3/8” - 16 x 1 1/4” swing bolt with the tab pointing to the rear of the chassis. Secure with a 3/8” washer and 3/8” - 16 x 1” bolt.
- Prepare spacer mounts as described in step 8.
- Rotate stabilizer tubes toward the center of the chassis and upward.
Operational Guidelines
Proper operation of the JT Strong Arm system is critical for its effectiveness and longevity. The documentation provides the following operational notes:
- Level the trailer side-to-side before proceeding.
- Lower the front of the trailer 3/4” lower than the rear.
- Lower and set the rear jacks evenly.
- Tighten the T-Bolts on the two rear Strong Arm Jack Stabilizers.
A critical safety note is included: when used with an automatic leveling system, the Strong Arms must be unlocked before retracting the jacks. Failure to do so may result in damage to the system or the vehicle.
Required Resources
Successful installation requires specific tools and materials. The documentation lists the following resources as required for preparation:
- Tape measure
- Felt-tip black marker
