JSC-24 dimensions and mounting points

Pair or individual replacement?

JSC-24 is the factory package of two jacks and one JCH-1 manual crank. JSC-24-IND is a single replacement jack without a crank. Their jack design is the same family, but the package quantity is different. A pair is useful for matching a front or rear set, while the individual jack is appropriate when only one unit requires replacement.

Jack shoes versus loose support blocks

The JBP-SJSC.2 product is a pair of moulded EPDM rubber shoes that stay attached to bowtie scissor-jack bases. The manufacturer says they protect the metal foot, provide additional ground contact and use supplied adapters to accommodate different bowtie lengths. These shoes do not change the jack's stabilizing capacity or replace a structurally sound mounting plate.

Installing and using a scissor stabilizer safely

Before drilling, check the proposed mounting position for frame wiring, LP-gas piping, water lines and other underbody equipment. The manufacturer calls for checking the closed-jack clearance and drive-socket access before permanent installation. Use the bolts or approved weld procedures specified for the RV frame. The JSC-24's 5,000 lb rating is a supporting/stabilizing capacity; scissor stabilizers should not be used to raise trailer tires clear of the ground or support an RV during underbody service.

For a longer 30-inch Stromberg jack, use the manufacturer JSC-30 mounting and parts drawings; it has a different hole pattern and a higher current supporting-capacity specification. Browse RV jacks and stabilizers or the Lippert PSX1 power stabilizer guide for a different electric stabilizer system.
