The bottom line is simple: this is a no-frills, robust aluminum cap set for owners who need a direct replacement that resists leaks and simplifies maintenance. The reviewer found the caps straightforward to install, well built from die-cast aluminum, and a sensible choice when an OEM-style non-locking cap is required for trucks from the mid 1990s through 2016.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits a wide span of Peterbilt models from 1995 to 2016, ensuring a correct fit for common heavy-duty trucks without modification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Replacement:\u003c\/strong\u003e Replaces common OEM part numbers such as 11-04859-100 and 11-04859-200 so mechanics can swap caps without adapting the filler neck.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAluminum Construction:\u003c\/strong\u003e Die-cast aluminum alloy body offers durable corrosion resistance and a solid seal that helps prevent fuel leakage under normal service conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Release:\u003c\/strong\u003e Built-in pressure release makes replacing the cap and relieving tank pressure easier and reduces the chance of spills during maintenance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Kit:\u003c\/strong\u003e Each set includes two 4 in caps, rubber sealing rings and a 13 in safety chain so installation is usually completed without extra parts.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe ideal buyer is a Peterbilt owner or fleet maintainer looking for an affordable, OEM-style non-locking replacement cap for models from 1995 to 2016, including 330, 379, 389, 579 and 587.
