Keep your KZ-built RV slide-out operating smoothly with the correct OEM-spec replacement head assembly. The Lippert 151474 is the tall-profile adjustable head assembly designed specifically for 1-3/8 in. V-Tech slide-out mechanisms found in KZ-manufactured coaches. When your slide room binds, seals unevenly, or won't seat properly, the head assembly is often the culprit -- and using the exact Lippert-sourced part ensures proper fit, correct travel geometry, and reliable long-term operation.
Lippert Components supplies the slide-out hardware for a large percentage of towable and motorized RVs on the road today, including units built by KZ Recreational Vehicles. The V-Tech slide system uses a rack-and-pinion or cable-driven mechanism depending on model year, and the adjustable head assembly is the interface point between the slide room structure and the drive mechanism. Getting the correct profile -- in this case, the tall variant -- is critical. Installing a standard-height head in an application that requires the tall configuration will result in misalignment, accelerated seal wear, and potential slide-room damage.
Part number 151474 is the Lippert-designated assembly for KZ applications requiring the 1-3/8 in. V-Tech head in tall profile. Match this part number against your coach's Lippert parts tag (usually found inside a cabinet near the slide-out mechanism) before ordering.
Tall-profile design matches the OEM geometry of KZ coach slide rooms that require added vertical clearance in the head assembly -- prevents binding and uneven travel.
Sized for the 1-3/8 in. V-Tech slide-out drive system. Using the wrong diameter head assembly risks damage to the rack or drive tube.
Built-in adjustability allows fine-tuning of slide room engagement and seating, compensating for minor frame flex or wear over time without replacing the full mechanism.
Sourced directly from Lippert Components -- the same manufacturer that supplied the original hardware. No fitment guesswork with aftermarket substitutes.
In Lippert's V-Tech slide-out system, the head assembly is the end-cap fitting that mounts to the slide tube and engages the slide room during extension and retraction. The adjustable version allows the installer or technician to set the engagement depth and angle, which is especially useful during initial installation or after the slide room has been re-sealed or re-skinned. The tall variant provides additional vertical engagement surface compared to the standard-height part -- this is a factory-specified dimension, not a universal upgrade.
Replacement of the V-Tech head assembly is a moderate DIY repair for owners comfortable working with slide-out mechanisms. The slide room must be fully extended and the drive system de-energized before removal. Refer to the slide tube diameter and existing head orientation before installing the new assembly to confirm the tall profile is correct for your specific room configuration.
