Ever cut a ride short because a surprise downpour soaked you to the bone? Or maybe you’ve felt that biting wind on a cold morning trail and wished you had just a bit more protection. We’ve all been there. Your Polaris RZR is a beast of a machine, but without a full cab, you’re at the mercy of the elements.
That feeling of being blasted by mud, dust, or icy rain can turn an epic adventure into a miserable slog back to the trailer. You invested in your RZR for freedom and fun, not to be uncomfortable.
This is where a high-quality polaris rzr upper door kit completely transforms your experience. Imagine sealing your cab from the elements, extending your riding season into the colder months, and keeping the interior clean and dry. It’s a game-changer for comfort and enjoyment.
In this complete guide, we’ll walk you through everything you need to know. From choosing the right kit to a step-by-step installation, and even how to care for your investment for years of use. Let’s get your RZR buttoned up and ready for anything.
Why Your RZR Needs an Upper Door Kit: The Core Benefits
You might be wondering if this upgrade is truly worth it. As seasoned riders, we can tell you unequivocally: yes. A quality set of upper doors is one of the most practical and comfort-enhancing mods you can make. Here’s a breakdown of the key benefits.
All-Weather Protection
This is the number one reason riders install an upper door kit. It’s your shield against the unpredictable. Rain, snow, sleet, or that freezing wind on a winter ride are no longer a problem.
A sealed cab means you and your passengers stay warm and dry. This single benefit can literally double your riding season, letting you hit the trails in early spring and late fall when others have already packed it in.
Reduced Cabin Noise and Debris
Half doors are great, but they do little to stop the constant barrage of dust, mud, and trail debris from entering the cab. Upper doors create a complete barrier, keeping your interior significantly cleaner.
They also drastically cut down on wind noise at higher speeds. This makes conversations easier, reduces fatigue on long rides, and lets you enjoy the sound of your machine—not the howling wind.
Enhanced Safety and Security
While not a replacement for a full roll cage, upper doors add a perceived layer of security and containment. They help prevent branches and other trail hazards from entering the cab and potentially injuring an occupant.
They also provide a small but welcome sense of security when you park your RZR, keeping prying eyes off any gear you might have inside.
Choosing the Right Polaris RZR Upper Door Kit: A Buyer’s Guide
Not all kits are created equal. Making the right choice upfront will save you headaches down the road. This polaris rzr upper door kit guide will help you navigate the options based on your riding style, climate, and budget.
Soft Uppers vs. Hard Uppers
This is the biggest decision you’ll make. Each has distinct pros and cons.
- Soft Upper Doors: Typically made of marine-grade canvas or vinyl with a clear vinyl window. They are flexible, lightweight, and often more affordable. The biggest advantage is their versatility—you can often roll up the windows or remove the doors entirely with relative ease.
- Hard Upper Doors: Usually constructed from polycarbonate with a metal frame. They offer superior sealing, durability, and scratch resistance. They provide a more “finished,” automotive-like feel but are heavier, more expensive, and less convenient to remove on the trail.
Material Matters: What to Look For
Pay close attention to the materials used. For soft doors, look for rip-stop vinyl or marine-grade polyester for the fabric portion, as it resists tearing. The clear window should be a heavy-gauge, UV-resistant vinyl to prevent yellowing and cracking.
For hard doors, polycarbonate is the gold standard. It’s incredibly impact-resistant. Look for models with a hard coating on both sides to maximize scratch resistance, which is a common complaint with uncoated versions.
Compatibility Check: Match Your Model and Year
This seems obvious, but it’s a critical step. The RZR chassis and factory door designs have changed over the years. Always double-check that the kit you’re buying is specifically designed for your RZR’s model and year (e.g., RZR XP 1000, Pro XP, Trail S).
Also, confirm compatibility with your existing lower doors, whether they are factory or aftermarket. Most kits are designed to mate perfectly with stock lowers, but it’s always wise to verify.
How to Install Your Polaris RZR Upper Door Kit: A Step-by-Step Guide
Alright, you’ve got your kit. Let’s get it installed. This process is well within the reach of a careful DIYer. Grab a friend, as a second set of hands makes alignment much easier. Here’s how to polaris rzr upper door kit installation is done right.
Tools and Prep
Before you start, gather your tools and lay out all the parts from the box. Compare them to the parts list in the instructions to ensure nothing is missing.
You’ll typically need:
- A basic socket set (metric and/or standard)
- Torx bit set (Polaris loves Torx bolts)
- A utility knife
- A drill and bits (sometimes required)
- A clean, well-lit workspace
Thoroughly clean your RZR’s roll cage and lower doors. A clean surface ensures a better seal and prevents scratching during installation.
Step-by-Step Installation Process
Note: These are general steps. Always refer to the specific instructions included with your kit, as designs vary.
- Attach Mounting Hardware: The first step is usually to attach any brackets or mounting points to your RZR’s roll cage. Leave the bolts slightly loose for now to allow for adjustment.
- Prepare the Lower Doors: Some kits require you to drill small holes in your factory lower doors to mount the upper frame. Measure twice, drill once! Use the provided template if one is included.
- Mount the Upper Door Frame: With the help of a friend, carefully align the upper door frame with the mounting brackets on the roll cage and the attachment points on the lower door. Start all the bolts by hand to avoid cross-threading.
- Align for a Perfect Seal: This is the most crucial step. Close the door and check the alignment. You’re looking for an even gap all the way around and good contact with the weatherstripping on the roll cage. Adjust the frame as needed until it sits perfectly.
- Tighten Everything Down: Once you’re happy with the alignment, systematically tighten all the mounting bolts. Don’t overtighten, as this can damage the frame or your RZR’s cage. Work in a crisscross pattern to ensure even pressure.
- Install the Door Skin/Panel: For soft doors, this involves stretching the fabric over the frame and securing it with Velcro or snaps. For hard doors, you’ll bolt the polycarbonate panel into the frame.
- Repeat on the Other Side: Follow the same process for the other door.
Pro-Tips for a Perfect Fit
Here are some polaris rzr upper door kit tips from the field. Installing on a warm day or in a heated garage can help. Soft vinyl materials are more pliable when warm, making them easier to stretch for a tight, wrinkle-free fit.
Don’t fully tighten any bolts until the entire door is mounted and aligned. This gives you the wiggle room needed to get a perfect, draft-free seal.
Common Problems with Polaris RZR Upper Door Kits (And How to Fix Them)
Even the best kits can have minor issues. Knowing how to troubleshoot these common problems with polaris rzr upper door kit installations will keep you happy on the trail.
Leaks and Drafts
A small gap can let in a surprising amount of cold air or water. The fix is usually alignment. Loosen the mounting bolts and readjust the door for a tighter fit. You can also add thin, self-adhesive foam weatherstripping (available at any hardware store) to problem areas for an even better seal.
Zipper Jams and Failures
This is a common issue with soft doors. Zippers get clogged with mud and dust. The key is preventative maintenance. Regularly clean the zipper teeth with a brush and apply a zipper lubricant. If a zipper fails, many upholstery shops can replace it for a reasonable price.
Scratched or Hazy Windows
Vinyl and polycarbonate windows can scratch easily. Never wipe them when they are dry and muddy. Always rinse with plenty of water first, then use a gentle microfiber cloth and a plastic-safe cleaner. Minor scratches can often be polished out with a dedicated plastic polish.
The Ultimate Polaris RZR Upper Door Kit Care Guide
Proper care will dramatically extend the life of your investment. Following these polaris rzr upper door kit best practices will keep your doors looking and functioning like new.
Cleaning Best Practices
For the entire door, start by gently hosing off all loose mud and dirt. Use a mild soap (like a car wash soap) and a soft microfiber mitt. For clear vinyl or polycarbonate windows, use a dedicated plastic cleaner or a simple solution of mild soap and water. Rinse thoroughly and pat dry with a clean microfiber towel to prevent water spots.
Storage Tips for Off-Season
If you remove your soft doors for the summer, store them correctly. Clean them thoroughly first. Lay them flat or roll them loosely with a towel in between the vinyl windows to prevent creasing and scratching. Store them in a cool, dry place away from direct sunlight.
Zipper Lubrication and Maintenance
For soft doors, zipper care is paramount. After every few rides (or after any particularly muddy one), clean the zipper teeth with an old toothbrush. Apply a silicone-based zipper lubricant spray or a wax stick to keep them running smoothly and prevent corrosion.
Thinking Green: The Sustainable Polaris RZR Upper Door Kit Approach
Being an off-roader means respecting the environments we play in. A sustainable polaris rzr upper door kit philosophy is about maximizing lifespan and minimizing waste.
Extending the Lifespan to Reduce Waste
The most eco-friendly product is the one you don’t have to replace. The care tips above are your first line of defense. By cleaning, maintaining, and storing your doors properly, you can get many more years of service, which is better for your wallet and the planet.
Repairing vs. Replacing Components
Don’t throw away a set of soft doors because of a small tear or a broken zipper. A local marine or auto upholstery shop can often patch tears and replace zippers for a fraction of the cost of a new kit. This repair-first mindset is a core part of an eco-friendly polaris rzr upper door kit strategy.
Eco-Friendly Cleaning Solutions
You don’t need harsh chemicals. Biodegradable car wash soaps and simple vinegar-and-water solutions can be effective cleaners. This reduces the chemical runoff when you’re washing your rig after a long day on the trails.
Frequently Asked Questions About Polaris RZR Upper Door Kits
Can I use upper doors with any lower doors?
Generally, no. Most upper door kits are designed specifically to integrate with the stock Polaris lower doors for your RZR model. If you have aftermarket lower doors, you must find an upper door kit made by the same manufacturer or one that explicitly states it’s compatible with your specific lowers.
Will upper doors make my RZR too hot in the summer?
They can trap heat, yes. That’s the beauty of versatile designs. Many soft upper doors have zip-down windows for ventilation. For maximum airflow, you can simply remove the upper doors for the hot summer months, a process that usually takes only a few minutes once they’re initially installed.
How hard is it to remove the upper doors once installed?
It’s typically very easy. Most designs use a few bolts or a quick-release latch system. Once the initial, more involved installation and alignment are done, taking them on and off for the season is usually a 5-10 minute job.
Do soft upper doors flap around at high speeds?
A high-quality, properly installed soft door should not flap excessively. A snug fit is key. If your doors are flapping, check the tension and ensure all Velcro and snaps are securely fastened. A tight, drum-like fit is what you’re aiming for.
A polaris rzr upper door kit is more than just an accessory; it’s an investment in comfort, protection, and more time on the trail. By choosing the right kit and taking care of it, you’ll be ready to tackle any adventure, in any weather. Stay safe, stay comfortable, and we’ll see you out there!
