At Jeep Speed Shop, we understand some customers want to perform their own Jeep V8 Hemi swap to save money and earn bragging rights. So, we offer a DIY version of our 50-state smog legal conversion for 2007-2011 Wrangler JK models.

The kit is a great way to have fun getting your hands dirty – and it’s the best way to stuff a Hemi in your Jeep.

Jeep Speed Shop V8 Hemi conversion – the only logical choice

Although there are many Jeep Hemi swap kits on the market, there’s only one to consider if you live in California: the conversion from Jeep Speed Shop. Why? Because our kit is certified by the California Air Resource Board (CARB), making it 100% smog legal in all 50 states.

Our conversion offers many other perks as well. For instance, we’ve engineered each part to perfection, so the kit is ultra-easy to install. Many of the components, which are all brand-new, are made in house and can only be ordered from Jeep Speed Shop.

In other words – we’ve devoted countless hours to make this kit the best, so your Jeep Hemi swap is quick and easy to perform. Our blood, sweat and tears have also gone towards making this conversion the most durable and long-lasting on the market.

If you’ve come this far, chances are, you’re genuinely interested in adding V8 power to your Jeep. And you’ve probably got questions; for which, we’ve got answers.

What does the Jeep Wrangler Hemi conversion kit cost?

Indeed, the saying ‘you get what you pay for’ holds true when it comes to Jeep engine swaps. You could get one of those cheap, basic kits and end up frustrated without everything you need – or you could start with the best: a kit from Jeep Speed Shop.

Even though a high-quality conversion, such as ours, costs a fair amount, you’ll know it was worth every penny as soon as your Hemi-powered Jeep rumbles to life.  

With our kit, everything required for a painless conversion, including a remapped PCM, is included in the $8,450 price. When you break down the list of components individually, it becomes clear the bundle is a cost-effective way to get V8 power.

And what about shipping? Depending on your location and the add-ons you select, expect to pay between $180 and $400 for delivery. Actual costs may vary. Altogether, the kit weighs 170 lbs. and fits into a box measuring 60 x 18 x 24 inches.

What are the requirements to keep the kit 50-state smog legal?

To keep your Jeep JK swap 50-state smog legal, a specific engine and transmission must be used in the conversion. The CARB has approved the 5.7L Hemi with variable valve timing (VVT) and 545RFE automatic for use with our kit. If any other powertrain combination is used, our conversion is legal for off-road use only.
