Full aluminum belly pan (bellypan) coverage for the Rockzilla 4-link Jeep Wrangler JL, engineered as the Next Venture 7000-Series Belly Skid System.
JL 7000-Series Aluminum Belly Skids – Rockzilla 4-Link Version (Rock Krawler Suspension)
Built for JL owners stepping up to a true triangulated 4-link and rear-mounted fuel cell, this version of our 7000-Series belly skids is designed specifically to work with the Rockzilla 4-Link System from Rock Krawler Suspension. You keep all the strength and glide you expect from 7075 + UHMW, while clearing the Rockzilla crossmember and ditching the factory fuel tank.
From the engine to the transfer case (and the leading edge of the fuel tank skid), this kit is identical to our standard JL 7000-Series skid system. Behind that point, it swaps the full-length fuel tank skid for a dedicated plate and crossmember section designed to tie into a Rock Krawler Rockzilla-style triangulated 4-link with no center-mounted fuel cell.
If you’re going all-in on hardcore rock crawling with a Rock Krawler Rockzilla setup and a rear-mounted fuel cell, this is the JL belly system that lets you keep the “race-proven” 7000-Series architecture under the middle of the Jeep.
Full Kit or Conversion Kit
We offer this in two configurations:
-
Full 7000-Series Rockzilla Belly Kit
Complete engine, transmission, transfer case, and forward fuel-tank section—plus the Rockzilla-specific rear belly plate/crossmember section designed around the Rock Krawler Rockzilla 4-Link System.
-
Conversion Kit for Existing JL 7000-Series Skids
Already running our standard JL 7000-Series belly skids and switching to a Rock Krawler Rockzilla triangulated 4-link with a rear-mounted fuel cell?
You can keep the bulk of your existing system. The conversion option replaces only the fuel-tank portion with the Rockzilla-compatible section, reusing your original 7000-Series brackets and skid components from the transfer case forward.
Construction & Materials
-
Skids: 3/16" 7075-T6 aluminum alloy
-
Wear layer: 1/4" UHMW on all primary belly panels for a smooth, hang-up-free glide
-
Bracketry & structure: Zinc-plated steel brackets and reinforcements, shared with our standard JL 7000-Series systems
-
Design: Recessed hardware, interlocking panels, and a continuous skid surface to keep the belly high, smooth, and protected
The layout is designed to keep the “big, beefy” crossmember and skid structure in the center of the Jeep, allowing the 7075 to flex and return without compromising strength—exactly what you want when you start pushing a JL into Rockzilla-level terrain.

Fuel Cell & Suspension Compatibility
-
Intended for:
Rock Krawler Suspension’s Rockzilla triangulated 4-link style rear suspensions with a rear-mounted fuel cell.
-
Not supported:
Mid-mount / center-mount fuel cells. We have no plans to offer a version for center-mounted fuel cells; this system is specifically laid out around a rear-mount cell so we can retain maximum structure and crossmember strength in the middle of the Jeep.
If your build deletes the factory fuel tank in favor of a rear-mounted fuel cell with a Rockzilla-style 4-link, this kit keeps the JL belly tied together with our 7000-Series layout while clearing your new suspension and fuel system.
Common Question: Can I Upgrade Later?
Q: I already have your JL 7000-Series skid system. If I later switch to a Rock Krawler Rockzilla triangulated 4-link and rear-mounted fuel cell, do I have to buy the whole kit again?
A: No. Order the conversion kit configuration and you’ll reuse all of your existing 7000-Series brackets and skid panels from the transfer case forward. You’re only swapping out the fuel-tank section for the Rockzilla-compatible rear belly section.
