Description
Product Overview
The iFJF Lower Door Insert Panels are designed to close the gap on Polaris RZR half doors — keeping mud, rocks, sticks, and trail debris out of the cabin. If you've ever taken your RZR through a mud hole only to have the floorboards fill with crud, you know exactly why these exist. These panels fill the lower opening on factory half doors, dramatically improving cabin cleanliness and passenger comfort without the cost or complexity of full door kits. Compatible with 2014-2020 Polaris RZR XP 1000 4-door and Turbo 4-door models.
Key Features
-
Keeps the Cabin Clean: Blocks mud, gravel, sticks, and water spray from entering through the lower door opening — your passengers stay clean and your interior stays dry.
-
Clip-On Installation: No drilling, no cutting, no permanent modification. Panels attach to the factory half door frame using the included spring clips and mounting hardware. Installation takes 15-20 minutes per side.
-
Heavy-Duty UV-Stabilized Poly: Made from thick, impact-resistant polymer that won't crack in sub-zero temperatures or warp in desert heat. Textured black finish matches factory interior plastics.
-
4-Door Set: This kit includes all four lower door inserts — front left, front right, rear left, rear right — for complete coverage on 4-door RZR models.
-
OEM-Look Integration: Designed to blend with the factory door shape and interior styling — looks like it came from the Polaris factory, not a backyard garage mod.

Why You Need Lower Door Inserts
Polaris RZR half doors provide rollover protection and a secure armrest — but their open lower section is a major design compromise. Every trail ride becomes a cleanup session: mud on the seats, gravel in the cupholders, and water soaking the floor mats. Lower door inserts solve this problem at a fraction of the cost of full doors while maintaining the open-air feel that makes a RZR fun to drive. Unlike fabric door lowers that flap, sag, and tear, these rigid polymer panels stay put and last for years.
Installation Guide
- Clean the inner door frame surface where the panel will attach.
- Position the lower insert against the door frame opening — align the mounting points.
- Attach spring clips to the panel edge tabs.
- Press the panel firmly onto the door frame — clips snap into place with an audible click.
- Secure any additional screw points through the provided pre-drilled holes.
- Repeat for the remaining three doors. Check that all panels are flush and secure before riding.
Frequently Asked Questions
Q: Will these fit a 2-door RZR?
A: No. This kit is specifically for the 4-door (crew) RZR models. The 2-door lower door opening dimensions are different.
Q: Are these compatible with aftermarket doors?
A: These are designed for factory Polaris half doors. Aftermarket doors from companies like Pro Armor, Assault Industries, or DragonFire have different frame geometries — verify fitment before ordering.
Q: Can I still use my factory door nets with these installed?
A: Yes. The inserts mount to the lower door frame and do not interfere with the upper door net or latch mechanism.
Q: Will these warp in high heat?
A: The UV-stabilized polymer is rated for continuous exposure up to 180°F. Arizona summers and desert riding won't cause warping or deformation.
Q: Can these be painted or wrapped?
A: The textured surface accepts adhesion promoter and plastic-rated paint. For wraps, a light scuff with 400-grit sandpaper improves vinyl adhesion. Test a small area first.
