Yarlung Set of 10 Boat Trailer Bunk Slide Pads and Glide Bunk Enders
The Yarlung kit includes eight bunk slide pads and two glide bunk enders, measuring 10.25 inches long by 3.1 inches wide. It is designed to fit most bunks on trailer systems, with compatible bunk sizes of 2, 4, and 6 inches. This set aims to simplify the loading and unloading process by reducing resistance between the hull and bunk surfaces. It is suitable for fiberglass boats up to 1500 lbs and metal boats up to 4000 lbs. Users should ensure the boat is fully unhooked before water exit to avoid slide-offs on steep ramps.
Caliber Bunk Wrap Kit 23050-BK
This kit provides a permanent replacement for carpet on boats, pontoons, PWC, lifts, and trailers. It includes a 16-foot roll of 2×4-in bunk wrap in black, along with endcaps and hardware. The wrap is designed to significantly reduce loading force, potentially reducing wear and tear on the boat, trailer, and winch. The kit aims to deliver durable protection under repetitive loading and hauling tasks, helping extend bunk life and hull protection.
(2) 6′ Black PermaBunk Boards
Two 6-foot carpeted PermaBunk boards made from recycled HDPE provide durable bunk runners that resist rot, moisture, and wear. The boards measure 2×4 inches in cross-section by 72 inches in length. They are designed to be long-lasting, with a focus on hard-wearing, mold and mildew resistance. They offer a low-maintenance alternative to traditional carpeted bunks and are suitable for various trailer setups requiring sturdy, water-resistant bunk surfaces.
(2) 8′ Black PermaBunk Boards
This listing also features two 8-foot boards in a black 2×4 HDPE design. The extended length increases bunk coverage and load distribution, helping to prevent hull contact hotspots. Like the 6-foot version, these boards resist rot, moisture, and staining while maintaining structural integrity under repeated loading cycles. They are suitable for a wide range of bunk trailer configurations and boat types, including heavier loads and painted or unpainted hull surfaces.
Surfix Trailer Bunk Glides 4″ x 72″ Kit of 2
The Surfix bunk glides are designed for fiberglass and aluminum boats, PWC, and pontoons. The kit includes two solid high-density polyethylene glides, each 1/2 inch thick, offering full bunk support with a low-profile design. Their construction emphasizes a rugged understructure to minimize hull contact points and prevent wear on hull finishes. The kit employs metal fasteners with slotted pockets to accommodate temperature changes and reduce loosening over time.
Caliber Bunk Wrap Kit 23054-BK, 24-ft Roll
A longer 24-foot roll of bunk wrap with endcaps, black in color, designed for permanent carpet replacement across boats, pontoons, and PWC setups. The kit includes end caps and hardware, delivering a substantial loading force reduction for trailers and wenches. This option is suitable for larger bunk configurations and higher-use trailers, providing a durable, low-maintenance alternative to traditional carpeted bunks.
Buying Guide
Key considerations when choosing plastic boat trailer bunks include material durability, weight capacity, compatibility with your bunk trailer, and hull protection. HDPE and composite plastics offer excellent moisture resistance, rot resistance, and long-term wear performance. Consider the hull material and weight class of your boat to select bunks that provide even load distribution and minimize hull abrasion. If you frequently load heavy boats, higher load ratings and longer bunks can improve stability during launches and recoveries. For painted bottoms, ensure your choice minimizes abrasion risk, or opt for glides designed to reduce friction on entry and exit ramps. Maintenance preferences also matter: carpet-free wraps or HDPE boards require less upkeep than traditional carpeted bunks. Finally, verify that end caps and hardware are included or readily compatible with your existing trailer system to avoid extra shopping trips.
Product perspective: For quick upgrades, the Yarlung kit offers ready-to-install slide pads and enders that can significantly ease loading. Caliber bunk wraps focus on hull protection and durability, suitable for long-term use across multiple trailer setups. PermaBunk boards provide rot-free, long-lasting bunk surfaces that excel in damp or coastal environments. Surfix glides emphasize optimized hull glide during entry and exit, reducing hull contact. NOVINO bunk slides and enders cover a broad range of bunk trailer configurations, combining ease of use with universal compatibility. Assess your trailer dimensions, bunk spacing, and boat weight to determine the best combination for reliable, safe launches and retrieves.
