The direct Lippert replacement weld-on head for hydraulic through frame slide-out systems. Designed to restore proper slide room travel geometry, this angle head with nut mounts to the slide rail frame and provides the wear surface needed for smooth, reliable slide operation.
Lippert's hydraulic through frame slide-out system routes the actuating cylinder through the chassis frame rails, relying on precision-machined head assemblies to transfer force and guide travel. When the weld-on head wears, cracks, or separates, the entire slide room can bind, misalign, or fail to retract fully -- problems that can leave you stranded on the road or unable to close up camp.
Part 159624 is the standard weld-on head with angle and nut, sold individually as a direct service replacement. It matches the OEM geometry for 2x2 hydraulic through frame slide-out assemblies found across a wide range of Lippert-equipped fifth wheels, travel trailers, and motorhomes.
Engineered specifically for Lippert 2x2 hydraulic through frame slide-out assemblies -- no modification required when replacing like-for-like.
Wear tab measures 6.5 in. L x 5.5 in. W x 1.875 in. H, providing a durable sliding contact surface that protects the frame and cylinder.
The mounting angle bracket and retaining nut are included with the head assembly, so you have everything needed for a complete weld-on installation.
One weld-on head assembly per package. Order the quantity that matches the number of slide rooms requiring service.
In a hydraulic through frame slide system, a hydraulic cylinder extends and retracts through openings in the chassis frame rails. The weld-on head assembly anchors to the frame at this opening, guides the cylinder rod, and provides the structural bearing surface that absorbs lateral and vertical loads during slide travel. The angled profile ensures the slide room moves squarely without racking or binding.
The wear tab surface is a sacrificial component -- it is meant to absorb contact wear so the frame itself is not damaged. Replacing a worn or cracked head assembly promptly prevents secondary damage to the cylinder, the frame opening, and the slide room seals.
Lippert hydraulic through frame slide systems are found on many popular fifth wheel and travel trailer brands built from the late 1990s through the present, including units by Forest River, Coachmen, Keystone, Heartland, and others. If your rig has a hydraulic power slide with the cylinder routed through the main frame rail -- rather than an electric motor or exposed exterior ram -- this system likely applies.
