How to Build a Truck Bed Slide? | Plywood To Pull-Out

Squatting and climbing into the bed every time you need cargo is the least-loved part of owning a pickup. A truck bed slide fixes it — a flat platform that rolls out past the tailgate — and learning how to build a truck bed slide with plywood, 2x4s, and heavy-duty drawer slides keeps the cost in the low hundreds. Both the DIY build and the bolt-in kit path are covered below.

What Does A Truck Bed Slide Actually Need?

Every truck bed slide, store-bought or homemade, is the same three components working together: a flat deck, a sliding mechanism, and a frame anchored to the bed. Nail those three and the rest is material choice.

• The deck. Most DIY builds use 3/4-inch plywood cut to fit between the wheel wells. Measure before you buy anything; bed width varies by inches between manufacturers and even cab styles.
• The slides. Heavy-duty full-extension drawer slides rated for several hundred pounds are the budget standard. For heavier loads, 8020 aluminum extrusion with roller bearings is stronger and smoother.
• The frame. 2x4s are the cheap, proven option; aluminum costs more and saves weight. Either way, the frame bolts through the bed floor.

Those are informal figures, not verified market prices, but they set a realistic budget — a fraction of what commercial slides cost.

Can You Build The Slide Yourself?

Yes. To build a plywood bed slide, cut a deck to fit your bed, mount drawer slides to a 2×4 frame on each side, and bolt the frame through the bed floor. The whole job is a weekend with basic tools, though a circular saw and a drill make it far easier.

1. Measure the bed. Record the width between the wheel wells and the length from the bulkhead to the tailgate opening, then subtract a couple of inches of clearance.
2. Cut the deck from 3/4-inch plywood, sand the edges, and seal them so moisture never softens the board.
3. Build the frame. Run 2x4s along each side so the deck sits above the slide rails, with a crosspiece near the bulkhead to keep it square.
4. Mount the slides to the frame rails, spaced to match the deck width, using the highest weight rating that fits and locking down the included stops so the deck can’t come off the rails.
5. Fit the deck. Screw the plywood to the frame and test the travel before bolting anything to the truck.

Lower the tailgate and pull. When it’s right, the deck glides out smoothly with one hand and stops before it overhangs too far. The classic failure is undersized slides that bind under load — skip drawer slides made for kitchen cabinets.

Installing A Bed Slide Kit Instead

A bolt-in bed slide kit installs in an afternoon with hand tools, and it adds a manufacturer-rated load capacity and warranty support a DIY build can’t promise. CargoEase’s installation steps follow a consistent order:

1. Protect the bed. Lay down cardboard before lifting the slide in so you don’t scratch the paint or liner.
2. Position the slide. Lift it in with the handle facing the tailgate, against the bulkhead.
3. Check the hardware. Some GM and Ford trucks need a lift kit so the slide clears the bed’s contours — confirm yours before drilling.
4. Align and drill. Line the frame up with the bulkhead marks, then drill 5/8-inch holes for the J-bolts.
5. Tighten and test. Run the J-bolts through the bed, check rear clearances and trim fit, and test the slide fully extended before loading it.
