Overview

The WeatherTech SillProtector (Part #ST004K1) is a custom-fit, impact-resistant door sill scuff plate engineered specifically for 4-door Jeep Wrangler JL owners who refuse to let daily wear and tear compromise their rig's interior. Precision laser-measured to match the exact shape, size, and contours of your Wrangler's door sills, this 4-piece set delivers full edge-to-edge protection against scratches, scuffs, and the kind of damage that passengers, gear, and trail dogs leave behind. Proudly designed, engineered, and manufactured in the USA, the SillProtector is the best door sill guard for 2018–2026 Jeep Wrangler 4-Door and Wrangler Unlimited models.

Key Features & Benefits

• Laser-Measured Custom Fit — Precision-engineered to exactly match your Wrangler JL's doorsill shape, size, and contours for a seamless, OEM-style appearance that looks factory-installed, not aftermarket.
• Edge-to-Edge Protection — Full-coverage scuff plate design shields the entire door sill surface from scratches, scuffs, claw marks, and boot scrapes caused by passengers, pets, and cargo.
• Impact-Resistant Material — Made from the same high-quality, durable plastic used in WeatherTech's BumperTopper line, built for long-lasting defense in even the hardest-used Jeeps.
• Industrial-Strength High-Bond Adhesive — Attaches directly to your door sill surfaces with very high-bond adhesive strips that hold firmly without damaging paint — and won't interfere with door closing or factory seals.
• Protects & Preserves Resale Value — Guards against costly new damage during ownership while concealing existing minor scuffs and blemishes, so your Wrangler looks its best at trade-in time.
• No-Drill, Tool-Free Installation — Clean, peel, and press install in minutes — no drilling, cutting, or professional labor required.
• Sleek, Low-Profile OEM Look — Slim design integrates flush with the door sill for a factory finish; doors close smoothly and factory seals remain fully intact.
• Made in the USA with Lifetime Limited Warranty — Designed, engineered, and manufactured in America. Backed by WeatherTech's Lifetime Limited Warranty against defects in materials and workmanship for the life of the original purchaser.

Installation

The WeatherTech SillProtector is a no-drill, tool-free installation designed for DIY completion in under 15 minutes. Start by thoroughly cleaning the door sill surface. Next, clean each SillProtector piece using the included alcohol prep pad. Then simply peel the adhesive liner and press each piece firmly into place. Allow 1–2 hours before driving for adequate adhesion, and allow 24 hours for full bond strength. Avoid washing the vehicle for 72 hours post-installation. For best results, install at temperatures of 60°F (16°C) or above — or inside a heated garage in colder climates. No professional installation required.

Frequently Asked Questions

Will the SillProtector interfere with my door closing or factory seals? No. The precision-measured, low-profile design fully accounts for door clearances, allowing doors to close smoothly and securely without interfering with factory seals or weatherstripping.

Is the SillProtector a true custom fit for my specific Wrangler? Yes. Each SillProtector is laser-measured specifically for your vehicle's make, model, and year — it is not a universal fit product. The result is an edge-to-edge fit that looks completely factory-installed.

Is this product CARB compliant or emissions regulated? The SillProtector is an interior protective accessory and is not subject to CARB or emissions regulations. California residents should note the Proposition 65 warning on the product packaging.

Does WeatherTech's Lifetime Limited Warranty cover this product? Yes. WeatherTech warrants this product to be free from defects in materials and workmanship under normal use for the lifetime of the original purchaser on the original vehicle it was installed in. Proof of purchase is required for warranty claims.
