LeerJack Truck Bed Jacking System | LEER
The LeerJack is our professional-grade lift-assist platform designed specifically for truck cap installation and bed-level work. Whether you're installing a new LEER cap, performing maintenance, or loading cargo, this system transforms your truck bed into a stable elevated workspace.
We engineered the LeerJack with a 500-pound load capacity and adjustable height settings from 6 to 18 inches, giving you safe access to work at optimal ergonomic positions. The wide stance base prevents tipping while the rubberized contact points protect your truck bed finish. Installation takes under five minutes with no tools required, and the compact folding design stores in your garage or behind the seat when not in use.

- Wide 24-inch stance base prevents platform tipping during use
- Rubberized bed contact pads protect truck finish from scratches
- Tool-free setup in under 5 minutes from storage to ready position
Platform Construction & Materials
We built the LeerJack around an aircraft-grade aluminum frame that delivers professional strength at a fraction of the weight of steel alternatives. The 18-pound total weight means one person can easily move the system from storage to your truck bed without assistance.
Each of the four corner pads features dual-density rubber that grips your bed liner while protecting the surface from pressure marks or scratches. The telescoping legs use a spring-loaded pin system that locks securely at each 2-inch height increment—no screws to adjust or lose. When folded, the entire platform compresses to a 4-inch profile that slides behind your truck seat or hangs on a garage wall hook.
Installation & Setup Process
Setting up your LeerJack requires no tools and takes less time than unboxing most equipment. Simply unfold the platform, extend the four legs to your desired working height, and lock the spring pins into the nearest adjustment holes. Place the assembled platform in your truck bed with the rubberized pads making full contact with the bed floor.
The 24-inch stance between legs provides exceptional stability even when you’re leaning over the platform edge to work on cap mounting hardware. We recommend positioning the LeerJack toward the cab end of your bed when installing caps, giving you optimal access to front mounting points while keeping your weight centered over the platform. For removal and storage, simply pull the four spring pins, collapse the legs, and fold the platform flat in one smooth motion.
Working Height Range & Ergonomics
The adjustable height system gives you seven distinct working positions from 6 inches up to 18 inches above your bed floor. Most installers find the 12 to 14-inch settings ideal for truck cap installation work, putting mounting hardware and seal channels at comfortable arm height without excessive reaching or bending.
For loading cargo or accessing roof rack mounting points on taller caps, the full 18-inch extension brings you closer to overhead work areas while maintaining the 500-pound capacity rating. The platform surface measures 20 by 24 inches, providing enough room to kneel comfortably or position equipment without crowding. Each height setting locks positively with audible clicks from the spring-pin mechanism, so you always know when the platform is secured at your selected position.

Common Questions About the LeerJack System
The LeerJack is compatible with all standard pickup truck beds from 5.5 feet to 8 feet in length. The 24-inch platform width fits comfortably between the wheel wells on full-size trucks, and the adjustable legs accommodate bed floor variations across different makes and models.
For compact trucks with narrower beds, check that your wheel well spacing allows at least 26 inches of clearance for stable platform positioning. The rubber contact pads adjust to minor bed floor angles automatically, so you don't need a perfectly level surface to achieve solid footing.
We rate the LeerJack at 500 pounds distributed load capacity, which covers the combined weight of most users plus tools and equipment. This rating applies across the full height range from 6 to 18 inches.
For reference, the average installer weighs between 150 and 220 pounds, leaving plenty of margin for drills, fastener boxes, and other installation gear. The wide stance design and aircraft-grade aluminum frame maintain stability even when you shift your weight to reach different areas of your truck cap during installation.
While the LeerJack can remain in your bed for short periods, we recommend collapsing and storing it when not actively in use. Road vibration and weather exposure can gradually loosen the spring pins from their locked positions, and leaving any platform in your bed reduces usable cargo space.
The folding process takes less than 30 seconds, and the collapsed unit stores easily behind your seat or in a garage. This approach protects your investment from unnecessary wear while keeping the platform ready for your next installation or maintenance project.
Yes, the LeerJack works with all common bed protection systems including drop-in plastic liners, spray-in bedliner coatings, and rubber mats. The dual-density rubber pads grip textured spray-in surfaces effectively while protecting smooth drop-in liners from pressure marks.
If you use a thick rubber mat over your bed floor, you may need to select one height setting higher than you would on a bare bed to achieve the same working elevation. The spring-pin adjustment system accommodates the extra material thickness without affecting the platform's stability or weight capacity.
Most users complete the full setup in three to five minutes during their first use, with that time dropping to under two minutes once you're familiar with the process. The sequence is straightforward: unfold the platform, extend the four legs to your chosen height, lock the spring pins, and place it in your truck bed.
There are no tools required and no adjustment screws to tighten. The spring-loaded pins click audibly when they engage each height setting, giving you immediate confirmation that the platform is locked and secure. Breakdown for storage reverses the same steps in about the same timeframe.
The 500-pound capacity technically allows two average adults on the platform simultaneously, but the 20-by-24-inch surface area makes this impractical for actual work. We designed the LeerJack for solo use, giving one person a stable elevated workspace with room to kneel, shift position, and place tools within reach.
For truck cap installation projects that require two people, we recommend one person working from the LeerJack while the other assists from ground level or the opposite side of the truck. This arrangement provides better access to mounting points around the cap perimeter than trying to crowd two installers onto a single platform.
For most truck cap installation work, the 12 to 14-inch settings position you at optimal ergonomic height to reach front mounting hardware and align seal channels without excessive bending. Start at 12 inches and adjust up if you find yourself reaching uncomfortably high, or down if you're bending too much.
When loading cargo or accessing roof-mounted equipment, the full 18-inch extension brings you closer to overhead work areas. The lower 6 to 10-inch settings work well for tasks that require you to crouch or kneel while working on bed-level components. The spring-pin system lets you change heights in seconds, so you can adjust positions mid-project as your task changes.
