KZL Fabrication Yoder YS640 BBQ Sliding Shelf Accessory Kit Review

What We Think

Ergonomic Game-Changer for the Yoder YS640

The Yoder YS640 and YS640s are widely celebrated for their heavy 10-gauge steel construction, outstanding smoke generation, and rock-solid thermal mass. However, reaching into the deep chamber of a 275-degree pit to baste, spritz, or probe a 18-pound packer brisket located near the back wall can test any pitmaster’s patience and forearms. The KZL Fabrication Yoder YS640 BBQ Sliding Shelf Accessory Kit w/ Drop-In was engineered specifically to solve this operational headache by converting static grates into smooth, full-extension sliding surfaces.

Build Quality & Engineering

KZL Fabrication did not skimp on materials when developing this kit. Built from thick, laser-cut steel or expanded metal and heavy-duty sliding mechanisms, the rack system matches the industrial tank-like aesthetic of the Yoder itself. The frame drops seamlessly onto the existing interior support rails of the YS640 without requiring permanent modification or drilling into your cook chamber. The slide tracks are engineered to handle intense heat and heavy grease exposure while supporting significant weight when fully extended out of the smoker shell.

Hands-On Testing & Performance

We put this sliding shelf kit through pit testing on a Yoder YS640s. We loaded the main rack with two 16-pound prime beef briskets and a full rack of St. Louis ribs. Extending the loaded rack completely outside the heat envelope proved rock-steady; the steel glides displayed zero structural flex or tipping hazard even under 35+ pounds of meat. The ability to pull the entire cooking surface out allows for fast, efficient spritzing, wrapping, and temp checks. Because you spend less time hovering over an open cook chamber with your arms inside the pit, lid-open heat loss is drastically reduced, helping the Yoder maintain rock-solid ambient temps.

Maintenance and Cleanability

The standout feature of this specific model is the integrated drop-in design. Cleaning static or bolted-in sliding shelf kits can be a nightmare, but KZL Fabrication engineered this system so the grate inserts can be lifted straight out of the sliding cradle for easy soak-and-scrub cleaning. The slide tracks themselves only require an occasional wipe down and a light dab of food-grade high-temp lubricant to keep the bearings sliding effortlessly through long, smoky cooks.

Final Verdict

If you already own a Yoder YS640 or YS640s, adding the KZL Fabrication Sliding Shelf Accessory Kit is one of the single best quality-of-life upgrades available. It turns a great pellet grill into an effortless cooking workstation, saving your sleeves from grease and your forearms from radiant heat burns.
