Reilly MotorSorts is the undisputed leader in performance Mopar suspension solutions. The AlterKtion front suspension is the focal point of performance for my 71 Challenger. Not only will you immediately experience modern sports car performance with your Mopar but you can hit the track hard on weekends with confidence. Mine has been tested with rigor on Brainerd, Laguna Secca and Sonoma. The performance of the RMS technology has far exceeded my expectations and without any difficulty or issues of any kind. Track performance limitations are no longer mechanical, but instead dependent on my ability to become a better driver. Bill Reilly is a professional and extremely helpful partner in Mopar performance. God bless him!

I have had my Alterktion on my 72 Challenger for many years now, love it! The Challenger is a Street/Land Speed car, handles everything I give it, adjustability is easy for all the conditions. Very satisfied. Great piece.

I have been running Reilly Motorsports AlterKtion and Street-Lynx suspension for almost 8 years. The suspension redefined my car and made it incredibly fun to drive. It handle so well that it opened doors for me to start auto crossing and running road courses. The build quality and customer service I have received from Reilly Motorsports is the best in the industry. Normally when you call in you are talking directly with the owner Bill. This was the best choice I made on my build and look forward to many more years ripping up the backroads and racetracks.

Excellent service on a terrific product, In a world that has lost integrity Bill still has that and more. I have been a happy customer for over 10 years no issues and great support. The quality and craftsmanship that goes into his products is second to none. If your in the market for Mopar suspension parts or one of his complete systems you won’t be disappointed. I have put 40,000 miles on his front suspension, it’s been driven hard from auto crossing and drag racing never an issue. My car rides better and corners better than the stock system.Scott

Bill was awesome to work with and he never hesitated to answer any of my questions nor did he ever try persuade me into buying his product. He explained the products features and a simple search for real-world results will speak for themselves. I have put nearly 1,000 miles on the Alterktion front suspension setup of my 70 Dodge Charger in a short period of time, and the handling and stability are nothing short of remarkable. The build quality is amazing and the installation was simple as long as the installer has some mechanical knowledge. I would not hesitate to purchase more products in the future.

I run a RMS front suspension in my 8 second drag car. I wouldnt trust no other aftermarket suspension on the market. Unlike the others Bill has engineered every piece. The kit is super easy to install. The instructions are very well written and easy to follow.

Fantastic product support! They offer the best in performance for your Mopar. Highly recommend! Our RMS front end fits perfect in our Plymouth! Thank you!

Used RMS suspension on many cars. Easy to install. Great handling. Don’t screw around, time to modernize. You’ll love it

If youre looking for a deluxe product and friendly and superb support, youre right at Reilly Motorsports.The team supported me and all my questions, after I purchased the complete set for front and rear axles and brake system.My 68 Coronet is a complete different car now. It was worth it!You wont find a better suspension or a better shop for your Mopar.Thanks to Bill and his crew!

Fantastic workmanship. Quality parts and great customer service before and after purchases. Very knowledge staff

I got an alterkation front and! rear suspension for my 68 cuda. It works great. A couple of friends got them front suspensions as well. Everyone is happy with it.Greetings from Germany

I utilize their front and rear suspension on my 65 barracuda. Quality and figment of parts are PERFECT. I wouldn’t go anywhere else for my mopar suspension needs! RMS customer service is excellent and answers within moments; for any questions you may have . Made in USA 10/10

Best Aftermarket Mopar Suspension system you can buy. Great quality, fit like a glove and a service after the sale. Best of all Bill is a real Mopar Guy...

I have been running his front and rear suspension for about ten years now and it has been great.

Reilly Motorsports second to none the customer service is way out of this league you speak to Bill personally he helps you out with anything that you need I recommend him to everyone who has a Mopar.

This is one of the best coilover alternations on the mopar market! Also how great and responsive they are to any questions! Customer service is 100%! I bought mine for a 72 resto challenger.

I have on my 1971 Road Runner an AlterKtion Suspension on front and a StreetLynx 4-Link rear, everything from Reilly Motorsport. Best suspension ever four your old Mopar! Handling and Steering is awesome! Bill Reilly is very helpful if you have questions. If you want the best handling and a lot of space for your big engine and headers, you need DEFINITELY the AlterKtion Suspension from Reilly Motorsport!

Weve used two of Reillys front suspensions in our latest rebuilds and finally bit the bullet on the street lynx rear for our 71 challenger. We were hesitant at first because the install seemed complicated and more than we could do in our garage without a lift. After getting the kit and installing it, I can proudly say that Bill and company make the make the absolute best suspension kits for your old Mopar. The fit and finish is unreal, and weve done them both in jackstands in the driveway. We have joked over the years about how many plug and play kits show up without plugs but this is the ideal kit because its all encompassing and it feels like it was made specifically for my car.The tech support is superior to almost any other part weve purchased because half the time we call the shop we can speak directly to Bill! Hes never not answered a question or not taken a minute to help.Overall Reilly motorsports is the absolute best in class. From start to finish youd be hard pressed to find a better company, better guy, and better product.

I have been a customer of Reilly MotorSports for many, many years, and their products are literally, second to none. The design, craftsmanship, and last, but, not least, their customer service is Grade AOne of the first Alterktion front ends that I purchased, was for a 1968 Barracuda, that I built for N/A 10.5 tire Heads Up racing, using an all aluminum, 1000+ Horsepower B1 Motor. I can personally attest to the quality of the Alterktion, as I felt like I could literally take my hands off of the steering wheel at 160+ mph, going down track. I later installed a 1300+ Pro Stock Hemi 99 motor, making the front end a bit heavier, however, there was zero change in the front end. 60 foot times in the low 1.20s, wheels up launches, and low 8 second passes, while always feeling as if the car was on a rail.Thank you, Reilly MotorSports!

Great place and great people, Bill always helped us with tech advise and of course parts!!! :-)
