Gulfstream GII

Jet Brella’s custom-engineered engine inlet cover system for the Gulfstream GII delivers robust protection for aircraft powered by the Rolls-Royce Spey 511 engines. Specifically designed for the GII, this dual-venting cover solution protects idle engines from environmental damage, ramp debris, and FOD (foreign object damage). Compact, lightweight, and built for quick installation, Jet Brella covers extend engine lifespan, reduce maintenance frequency, and support operational readiness during downtime. Available under part number G-300-2V, these covers are a smart investment for preserving the performance and integrity of the GII’s legacy powerplants.

Inlet Covers

Jet Brella’s inlet covers for the Gulfstream GII are shaped precisely to match the dimensions of the Rolls-Royce Spey 511 engine nacelles. Each unit weighs only 5.25 lbs and folds down to 37” high by 5” wide in its stowed position ideal for quick transport and compact storage. The dual venting system allows for passive pressure regulation while preventing intrusion from moisture, dust, birds, and debris. The cover is secured with a simple, efficient attachment system: a hook outboard and a snap inboard. A durable rubber cone with an integrated spinner bearing provides a snug fit that holds firm even in gusty conditions or active ramp environments.
