Windshield Defense Kit — INEOS® Grenadier®
Industrial-strength windshield protection, laser-cut for the Grenadier. Think of it as a screen protector for your windshield — take a rock strike, peel the layer, keep driving.
Industrial-Strength Protection from Rock Strikes
Gravel roads, trail drives, highway flying debris — the Grenadier windshield takes hits. Windshield Defense is a three-layer polyester film that absorbs the impact before it reaches your glass. When a layer gets chipped or pitted, peel it off and you have a fresh layer underneath. No shop visit, no replacement glass, no insurance claim.
Originally developed for IndyCar® racing — where windshield protection isn't optional — now available for your Grenadier. Same technology, same protection, same peel-and-go convenience.
Fits: INEOS® Grenadier® — Model 1924, Station Wagon, and Quartermaster™ (2022–present). Laser-cut to OEM windshield dimensions for a perfect fit.

Three Layers of Protection in One Installation
Install once, get three lives. Each of the three laminated layers is a full, independent shield over your windshield glass. When the first layer takes damage:
- Peel the top layer from the corner
- A fresh, undamaged layer is revealed
- Repeat when needed — up to three total replacements before reinstalling
Each layer provides 6+ months of protection under normal driving conditions. Heavy off-road use may vary.

Clear, UV-Protected Views
Crafted with optical-grade materials — no haze, no tint, no distortion. Just clear visibility with 99% UV protection built in.
|
Race-Tested, Adventure-Approved
Initially built for the high-speed demands of IndyCar® racing, now trusted by Grenadier owners who take their rigs off-road. When it's good enough for professional racing, it's good enough for the trail.

FAQ
|
Will this actually protect against rock chips and cracks?
Yes — Windshield Defense absorbs rock strikes and debris impacts that would normally chip or crack your glass. The film takes the hit instead of your windshield.
|
How long does each layer last?
Approximately 6 months per layer under normal use. Heavy off-road or highway driving may reduce that. When a layer is noticeably damaged, peel it off and the next layer is ready.
|
|
Does it fit the Station Wagon and Quartermaster?
Yes — fits all INEOS® Grenadier® variants: Model 1924, Station Wagon, and Quartermaster™ (2022–present).
|
Does it work on Gorilla® Glass?
Yes, and it's recommended. Gorilla Glass can still chip from rock strikes — Windshield Defense adds an extra layer of protection on top.
|
|
Can I install it on a damaged windshield?
We recommend installing only on undamaged, OEM windshields. Prior chips or cracks may become more visible under the film.
|
What's the professional install rebate?
If you choose to have Windshield Defense professionally installed, you can submit for a $25 Visa gift card rebate after installation. DIY installation is perfectly fine — the rebate is just a bonus for those who prefer a pro install.
