EQ Systems SL 13 HP Straight-Leg Hydraulic Jack | Part 7842 | 7,500 lbs | 13" Stroke | No Leg Switch

Replace or add an EQ Systems SL 13 HP Straight-Leg Hydraulic Jack (Part 7842) to your EQ Systems lifting or leveling system. 13" stroke, 7,500 lbs capacity, powder-coated for durability, and light for its capacity — well-suited to applications with limited ground clearance. This is the version WITHOUT a leg switch — for systems that report jack position another way or not at all. Available at The RV Surplus.

Fitment critical: Verify configuration before ordering. Call EQ Systems at 800-846-9659.

Making Sure This Is Your Jack

Body length is the fixed outer body measured with the jack retracted. Plate position is measured from the closed end of the body — positive toward the foot, negative past the closed end. Measure both before ordering, because EQ Systems has built the same model in more than one configuration.

Part 7842 appears on more than one row of the identification chart:

• 17⅜" body at 0" plate position (Obsolete — contact EQ Systems if yours matches)
• 16⅜" body at -⅞" plate position (this listing)
