Customer Reviews

Jeep Speed Shop has had the great pleasure of working with clients from around the world – here are a few snippets of what they have to say.

Michael Egli
2 years ago Absolutely amazing. If you look back at older reviews you'll see they went through a slump. Some bad staff left a few customers unhappy, but all of that has changed after management went through the business and wiped the slate clean. Now, they are once again the best engine swap experts for Jeeps HANDS DOWN. In my case...

Positive: Professionalism, Quality, Value Hats off to Todd what a fantastic job he did on my 07 Jeep JKU! I went with the 5.7 VVT Hemi truck engine with 8 speed transmission and it was one of the best decisions I ever made. I just got my rig back last week the sound of the V8, the smoothness of the 8 speed with manual sifter and all the powers I'm gained makes my Jeep become one of the bests around. It's also 100% Carb legal, which is a big deal for me since I'm from Cali...

Positive: Professionalism
Excellent service and communication – highly recommended if you want to put a Hemi V8 in your Wrangler. Todd and his crew were able to fix issues from another shop that did my original Hemi conversion which failed emission testing in CO. For over a year the original shop was not able to get my Jeep to pass emissions. Todd is the expert on CARB certified and emission compliant Hemi engine conversions. I now have a completely legal and beautiful Hemi JK. If you are going to put a Hemi engine in your Jeep, you should do it with Jeep Speed Shop as it will be done right and will be legal and pass emission testing the first time. It was well worth the drive from CO to CA. Thank you, Todd!

Hats off to Todd what a fantastic job he did on my 07 Jeep JKU! I went with the 5.7 VVT Hemi truck engine with 8 speed transmission and it was one of the best decisions I ever made. I just got my rig back last week the sound of the V8, the smoothness of the 8 speed with manual sifter and all the powers I’m gained makes my Jeep become one of the bests around. It’s also 100% Carb legal, which is a big deal for me since I’m from Cali. The customer service was outstanding and the communication was great! Todd’s been sending me the WIP pictures during the entire process. He even posted a video on YouTube and IG to show off my 8 speed. All in all, I’m beyond happy and so glad that I went with JSS for this project! Again, thank you Todd and Liz for everything you’ve done and I just hope your shop is closer to me! :)

Absolutely amazing. If you look back at older reviews you’ll see they went through a slump. Some bad staff left a few customers unhappy, but all of that has changed after management went through the business and wiped the slate clean. Now, they are once again the best engine swap experts for Jeeps HANDS DOWN.
In my case, the most recent project was a 2008 Jeep Wrangler Rubicon (not much left of the Rubicon though). 6.4 SRT Hemi Swap, Auto, Atlas 4 Speed. They not only tackled that with beautiful precision and an absolutely factory look, but they also took care of a half dozen other issues such as cleaning up some wiring from the previous owner, fixing ebrake issues, and much more.
Their communication has been stellar. Their professionalism amazing. And the quality of work is beyond words. If you are looking for an engine swap, do not pass Go, do not collect $200, call these guys ASAP and do whatever you can to let Todd do this for you.
