Gulfstream GIII

Jet Brella Gulfstream GIII Engine Covers

Jet Brella’s engineered engine cover system for the Gulfstream GIII is designed to provide complete protection for aircraft equipped with Rolls-Royce Spey 511 engines. Whether parked for an overnight stop or in long-term hangar storage, these inlet and exhaust covers guard against foreign object damage (FOD), ramp debris, and harsh weather conditions. Built for performance, quick setup, and longevity, Jet Brella’s lightweight, dual-venting covers preserve engine condition, reduce maintenance cycles, and support long-term aircraft readiness. Part Number: G-300-2V.

Inlet Covers

Designed specifically for the Gulfstream GIII, Jet Brella’s inlet covers fit the Spey 511 engine nacelles with precision. Each unit weighs 5.25 lbs and collapses to 37″ high by 5″ wide, making it ideal for compact transport and quick deployment. The dual-venting system prevents internal pressure buildup and reduces condensation during storage, while effectively sealing out birds, grit, moisture, and airborne contaminants. The covers are secured using a simple hook-and-snap hardware configuration (hook outboard, snap inboard). Each rubber cone includes a spinner bearing for added seal stability and flexibility. Carry bags with breathable mesh and vertical storage loops are included with every set.

Exhaust Covers

Jet Brella’s exhaust covers for the GIII complete the full-engine protection suite. Each unit consists of a vinyl-covered foam pillow supported by a rigid fiberglass backing plate, designed to resist nesting wildlife, sand, rain, and snow. Lightweight and secure, these covers are attached using plastic tether hooks and adjustable webbing straps, ensuring they stay firmly in place even under ramp turbulence and strong winds. Their soft structure prevents contact wear while offering maximum rear-engine protection.
