Gulfstream GIIB

Jet Brella Gulfstream GIIB Engine Covers

Jet Brella’s precision-engineered engine cover system for the Gulfstream GIIB is designed to provide full-spectrum protection for the aircraft’s Rolls-Royce Spey 511 engines. Ideal for ramp operations, overnight parking, or long-term storage, these dual-venting inlet covers prevent environmental damage, foreign object debris (FOD), and mechanical wear. Tailored exclusively for the GIIB, this system ensures lightweight handling, tool-free installation, and long-term durability—delivering dependable coverage with every deployment. The complete cover solution is available under Part Number G-300-2V.

Inlet Covers

Jet Brella’s inlet covers for the GIIB are purpose-built to match the contours of the Rolls-Royce Spey 511 engine nacelles. Each unit weighs just 5.25 lbs, with stowed dimensions of 37” tall by 5” wide. The dual venting design allows internal air pressure to equalize post-shutdown while preventing harmful debris, moisture, and wildlife intrusion. Installation is fast and solo-friendly, utilizing a hook (outboard) and snap (inboard) system that requires no tools or modifications. The rubber cone includes a built-in spinner bearing for added fit and durability. Each cover comes with a breathable mesh carry bag for easy stowage.
