Don’t risk your fuel system with poor-quality parts. Get a replacement from HHP!

Your Caterpillar 3126 is idling rough, misfiring when trying to accelerate or it’s consuming more fuel than normal. These are all symptoms of a failure in the fuel system. If you shop the competition, these problems could arise weeks, or days, after installation. Why? Our competitors are keen at making parts with a crisp, clean shine. But they aren’t experts at getting the necessary power to last another million miles.

At Highway and Heavy Parts, you'll get a fuel injector that has been manufactured in an ISO 9001:2015 certified facility, ensuring quality and consistency for your 3126. HHP offers only premium aftermarket parts for your 3126 at a much lower price compared to the OE manufacturer to help put money back in your pocket.

Each part is crafted with hard-wearing strength and durability to ensure your 3126 can withstand the rigors you put it through. It is also built to strict specifications for proper fitment and functionality.

As an added benefit, our parts are backed by our ASE-certified technicians on staff who can answer any technical question you have about your Caterpillar 3126.

With technical knowledge, quality products, fast shipping, and unbeatable customer service, HHP is the place to be!
