The Lippert 113535 is a direct-replacement front cylinder bracket engineered for 2x2 and 2.5x2.5 hydraulic slide-out systems. A worn or damaged front cylinder bracket is a common cause of sloppy, uneven slide movement -- this bracket restores the proper anchor point so your cylinder stays aligned and your room travels true. Compact and lightweight at just 0.5 lbs., it installs without fabrication on compatible Lippert hydraulic slide-out setups.
The front cylinder bracket is the structural link that locates and holds the hydraulic cylinder at the forward end of the slide-out assembly. Over time -- especially in rigs that see full-time use or frequent extension cycles -- the bracket can crack, deform, or loosen at its mounting points, causing the cylinder to shift and the room to rack or bind during travel.
Lippert part 113535 is the correct OEM-style replacement for both the 2x2 (2-inch square tube) and 2.5x2.5 (2.5-inch square tube) hydraulic slide-out configurations commonly found on Keystone and other Lippert-equipped trailers and fifth wheels. It is sold individually, so order two if both the front and rear positions need service at the same time.
Fits both 2x2 and 2.5x2.5 hydraulic slide-out cylinder tube sizes -- one part covers the two most common Lippert hydraulic configurations.
At 4.46" L x 1.5" W x 2.5" H and only 0.5 lbs., this bracket tucks into tight slide-out framing without interference or shimming.
Listed as Keystone RV part number 321107 -- makes dealer-sourced verification straightforward when confirming fitment on Keystone-built units.
Designed as a drop-in replacement with no cutting, welding, or custom fabrication needed on systems originally built with this bracket style.
Lippert hydraulic slide-out systems use a double-acting hydraulic cylinder to push and retract the room. The front cylinder bracket mounts at the leading end of the slide-out box and provides the fixed pivot or anchor point for the rod-end of the cylinder. When this bracket fails, the cylinder loses its reference point -- leading to uneven room travel, side-to-side racking, and excessive wear on the slide seals and wiper seals.
Replacing the bracket early, at the first sign of movement or visible cracking, prevents more expensive downstream damage to the cylinder itself, the slide-out floor framing, and the room seals.
This bracket is specific to hydraulic slide-out systems -- not electric motor-driven or cable-over-hydraulic systems. Lippert hydraulic slide-outs are identified by the presence of a hydraulic pump unit (typically mounted in a basement compartment), hydraulic lines running to each slide room, and double-acting cylinders visible along the slide-out framing rails.
