The RealTruck BAK Revolver X4 TS is the best-selling do-it-all hard roll-up bed cover now rack-ready. It takes everything that made the Revolver X4s the most secure hard roll-up in its class and adds integrated T-slot rails, so you can mount truck racks, cargo holders, rooftop tents, and cross bars right to the bed rails while still keeping your gear locked, dry, and hidden underneath. Roll it up for 100% bed access, roll it closed to lock cargo down under patented slash-resistant aluminum slats, and carry gear on top all in a sleek, stealthy matte black.

It's the ideal cover for the overlander, adventurer, or working pro who refuses to choose between a secure covered bed and the ability to haul gear above it bikes, kayaks, tents, ladders, cargo baskets. You get the X4s's signature Level-3 slash-resistant security, a 400 lb cover load rating, the lowest profile of any hard roll-up, and TriShield leakproof sealing, plus the versatility of a bed-rack platform and a 5-year warranty. If you want maximum security *and* over-bed cargo capability in one cover, this is it.

Key Features

• Integrated T-slot rack rails – Built-in T-slot channels in the bed rails let you mount truck racks, cargo holders, tents, and cross bars for a full over-bed upfit while keeping full use of the covered bed below
• Most secure hard roll-up – Patented rotational locking rails and automatic slam latches resist prying, slicing, and forced entry, especially paired with a locking tailgate
• Slash-resistant aluminum slats, 400 lb capacity – Patented interlocking aluminum slats deliver slash protection and support up to 400 lbs of evenly distributed weight on the cover itself
• TriShield leakproof engineering – One-piece aluminum-reinforced TriShield 70-grade vinyl with a full-perimeter sealing system (bulkhead, flush side seals, redesigned corner caps) for one of the most leakproof covers on the market

Retractable-Level Security, Rack-Ready Versatility
The headline upgrade is rack readiness. BAK built T-slot channels directly into the bed rails, so you can attach a rack system, cargo carrier, rooftop tent, or cross bars right to the cover's rails no separate bed rack towering over everything. And because the cover still rolls fully forward with PrecisionRoll technology, you get 100% bed access *and* your over-bed rack at the same time. It's the flexibility of a bed rack combined with a secure, weatherproof cover in one system.

Underneath the versatility, it's a full-strength Revolver. Patented rotational locking rails and automatic slam latches lock the cover down and resist prying and forced entry, while the patented interlocking aluminum slats are slash-resistant a knife won't cut through them like a soft cover's fabric. BAK rates this its highest Level-3 security, and there's no canister eating into your bed the way a retractable cover has. The 400 lb evenly distributed capacity applies to the cover surface itself.

Material and sealing are top-tier. The surface is a one-piece, aluminum-reinforced TriShield 70-grade vinyl in matte black, with no seams to leak, paired with a full-perimeter sealing system a heavy-duty bulkhead seal, flush side seals, and redesigned rear corner caps to keep your bed dry. As the lowest-profile hard roll-up, it sits nearly flush with the bed rails for an integrated look, and its 360° matte black finish carries across the slats, clamps, and hardware for a fully stealthy appearance in any position. It's also compatible with most 5th-wheel hitches. Fitment is vehicle-specific, so ordering the correct "RK" part number for your truck is essential.

*A note on rack loads:* the T-slot rails are designed to accept rack and cargo systems (sold separately), but the load you can carry on top depends on the specific rack you install and its rating always follow your rack manufacturer's weight limits. The 400 lb figure is the cover's evenly-distributed surface capacity, not a roof-rack rating.

Installation

• Difficulty: Level 1 Simple Installation.
• Time estimate: Under 1 hour on most applications.
• Tools required: Conventional hand tools; each order includes vehicle-specific hardware and instructions.
• Drilling/modifications: None. The clamp-on system requires no drilling.
• Rack setup: The T-slot rails are integrated into the cover's rails, so mounting a compatible rack is a matter of sliding hardware into the channels no separate rail kit needed on this version. (Racks and carriers sold separately.)
•  Important first-week step: Check all clamps and retention mechanisms for tightness after about a week of driving, and periodically thereafter good practice and a warranty condition.

What's Included

• (1) BAK Revolver X4 TS hard roll-up tonneau cover (aluminum slats with TriShield 70-grade matte vinyl, matte black)
• Integrated T-slot bed rails, clamps, and vehicle-specific hardware kit (matte black)
• Integrated safety straps and full-perimeter seals (bulkhead, side, corner caps)

Care & Maintenance

• Cleaning: Clean with mild automotive soap and water only. The matte vinyl is dust- and stain-resistant; avoid harsh chemicals or abrasives.
• Secure when driving: The cover must be secured at all points when the vehicle is in motion closed and latched, or rolled and secured with the safety straps.
• Clear before rolling: Remove snow, ice, and debris before rolling the cover up.
• Check the clamps and rack hardware: Confirm all clamps and retention mechanisms are tight after a week of driving following installation, and periodically after that; also check any installed rack hardware in the T-slots.
• Seal care: Keep the bulkhead, side seals, and corner caps clean and free of grit so they seal properly.

Warranty
The Revolver X4 TS is backed by a 5-Year Limited Warranty from BAK Industries.

• Covered: The cover is warranted to be structurally free from defects in materials and workmanship for 5 years from the original date of purchase.
• Not covered / voids warranty: Damage from accidents, misuse, neglect, improper installation/service/removal, modifications, acts of God, and normal wear and tear. Failure to follow the care and use instructions above will also void the warranty.
• Original purchaser only: Coverage applies to the initial purchaser and is not transferable. Keep your proof of purchase registration documentation and/or original purchase verification may be required to make a claim.

Terms to Know

• T-slot rail / T-slot channel: A slotted track (T-shaped in cross-section) built into the cover's bed rails. Rack feet and accessory hardware slide in and lock down, letting the cover carry racks and cargo systems without drilling.
• Hard roll-up tonneau cover: A bed cover of rigid slats (rather than fabric) that rolls up toward the cab combining hard-cover security and slash resistance with roll-up convenience.
• Slash-resistant / Level-3 security: BAK's highest security rating; the aluminum slats resist being cut through, unlike a soft vinyl cover.
• Rotational locking rails: Patented side rails that lock the cover down as it closes, resisting prying and forced entry.
• Automatic slam latches: Latches that engage on their own as the cover closes you simply close it to lock; the release cable unlatches them.
• TriShield 70-grade vinyl: BAK's aluminum-reinforced, multi-layer vinyl surface; "70-grade" indicates a heavier, more durable material.
• PrecisionRoll: BAK's technology for a smooth, controlled roll-up action.
• Full-perimeter sealing: A sealing system around the entire cover bulkhead, sides, and rear corners for maximum weather resistance.
• Evenly-distributed load: A weight rating (400 lbs here, on the cover surface) that assumes the load is spread across the cover, not concentrated in one spot.
