Pelican Sport Kayak Carrier Replacement Foam Blocks

Reference: These EVA foam blocks are compatible with Pelican’s Kayak Transport kit PS0481-3. They are sold separately to replace worn foams rather than purchasing a full kit. The blocks provide flexible shock resistance, better grip, and adhesive properties to stay in place during transport. They also come with anti-slip material for improved stability. Best for Pelican kit owners who want to extend the life of their carrier without replacing the entire system. Limitation: designed for Pelican’s specific kit; compatibility should be confirmed for non-Pelican racks.
WOOWAVE Deluxe Carrier Kit Universal Foam Blocks

Reference: This universal kit includes 2 foam blocks, 2 tie-downs, load straps, S-hooks, and a storage bag. The 12-inch gunnel-style non-skid EVA foam blocks fit round, square, and oval load bars, offering UV resistance and tear strength. Best for budget-minded shoppers needing a complete, ready-to-go setup. It’s better for shorter kayaks or lighter loads due to the fixed block size. Avoid this if you require longer blocks for oversized boats.

It includes 2 foam blocks, multiple tie-downs, load straps, and S-hooks, with UV and tear resistance for durability. It’s a solid choice for seasonal use and mixed weather. Best for users who want reliable, all-season performance and robust straps for highway speeds. Limitation: higher upfront cost relative to basic kits.
Innconee Universal Car Top Canoe Carrier Kit

Reference: Innconee’s kit provides universal foam blocks with two tie-downs, two load straps, S hooks, and a carrying bag. The 6.7-inch foam blocks offer stability for a compact roof setup and reduce scratching. Best for small boats or vehicles with limited roof space. Limitation: smaller blocks may require careful positioning for longer kayaks or wider hulls.
Buying Guide
What should you check first when selecting kayak foam blocks?
- Compatibility: Confirm the blocks fit your carrier system or roof rack type. Some blocks are brand-specific, others are universal.
- Block size and shape: Larger blocks can handle wider or longer kayaks; angled foam supports reduce hull contact points and scratches.
- Material and durability: EVA foam offers lightweight, shock absorption, and water resistance. Look for UV resistance for outdoor use.
- Security: Check for non-slip bottoms and included tie-downs or straps. A complete kit reduces the need for extra gear.
- Ease of use: Quick-install designs save time and reduce move-or-shift risks during travel.
How to install for best results?
- Place foam blocks on the vehicle roof per the manufacturer’s guidance, ensuring even contact with the rack or load bars.
- Use provided or high-quality straps to secure the kayak to the blocks and roof, avoiding over-tightening that could damage the hull or roof.
- Periodic checks during long trips help maintain security and prevent shifting with wind or road vibration.
What scenarios require special considerations?
- High-speed highway driving: Prefer kits with heavy-duty straps or longer load straps to maintain tension and reduce wind noise.
- Long or wide kayaks: Choose longer blocks or angled designs to cradle the hull fully and avoid contact with gutters or roof edges.
- Budget constraints: A complete, lower-cost universal kit can cover most casual needs without compromising basic protection.
