X4XZ Heavy-Duty Hood Latch Kit for Peterbilt, Kenworth & Mack - LH/RH 315-5502/315-5503, Corrosion-Resistant Pair

Heavy-duty replacement hood latch kit (left and right) designed to restore secure, quiet hood closure on select Peterbilt, Kenworth, Mack and Blue Bird models.

This X4XZ hood latch kit includes two heavy-duty latches (LH and RH) made as direct-fit replacements for OE# 315-5502 and 315-5503. Built from reinforced plastic and rubber with a corrosion-resistant shell, the pair installs without special tools and comes with a 12-month warranty. It’s intended for truck and bus service applications where worn or broken latches can cause hood rattle, accidental opening, or prevent proper sealing.

• Direct-fit design: no modification to hood or frame expected.
• Typical tools: basic socket set and screwdrivers.
• Quick installation reduces downtime compared with custom repairs.

What materials and durability features does this kit offer?

X4XZ engineered these latches using high-grade plastic and rubber components with a corrosion-resistant outer shell to improve resilience against vibration and weather exposure. The materials allow for wide-angle pulling and resist cracking under normal service conditions.

• Durable plastic and rubber construction for flexibility and toughness.
• Corrosion-resistant coating to extend service life in harsh environments.
• Designed to withstand repeated opening and closing without deformation.

Will replacing worn latches improve safety and noise?

A fresh set of latches helps ensure the hood stays securely closed at highway speeds and reduces rattling caused by loose or damaged catches. While it does not change other structural conditions, restoring latch function improves both cabin quietness and roadside safety by preventing unexpected hood movement.

• Reduces hood vibration and wind noise when driving.
• Prevents accidental hood opening that could obstruct view or cause damage.
• Pair included (LH and RH) for balanced performance on both sides.

Who this product is for: technicians, fleet maintenance managers, owner-operators and DIY truck owners who need a reliable, direct-fit hood latch replacement for Peterbilt, Kenworth, Mack or Blue Bird vehicles. It’s especially useful when original latches have worn, broken, or allow hood movement and noise; the kit restores proper function and is backed by a 12-month warranty for added confidence.
