This kit fits the superchargers listed in the description, as well as the units shown in our photos.

If you’re unsure, simply send us a photo of your supercharger, its serial number, or your car’s make and model, and we’ll confirm whether this kit is the right one for you.

If it turns out you need a different setup, no stress — we specialise in most Eaton supercharger models, and we’ll guide you to the correct kit or the best available alternative.

Your confidence and smooth rebuild experience are our top priorities.

At Boosttech Superchargers, we’ve been dedicated to keeping Eaton superchargers running at their best since 2014. What started as a small specialist workshop has grown into a trusted global supplier whose rebuild kits have been used on thousands of superchargers worldwide.

Over the years, we’ve earned a reputation for reliability, expertise, and genuine passion for the craft. Our customers choose us because we understand superchargers inside out and we’re always here to offer guidance, compatibility checks, and honest technical advice.

Our mission is simple:

Deliver exceptional quality at competitive prices, backed by friendly, knowledgeable support you can rely on. Every kit we supply uses carefully selected components, including premium INA bearings and Genuine GM 5W-30 supercharger oil, ensuring your rebuild is smooth, durable, and done to the highest standard.

Whether you’re an enthusiast, a professional rebuilder, or simply maintaining your own vehicle, we’re here to make the process easy, clear, and worry-free. Your supercharger is in good hands with us.
