2024 Rev9 Coilovers Review – Are They Any Good?
If you have been looking for budget coilovers you may have come across the name Rev9. Rev9 make coilovers which sell for extremely low prices, especially for the list of features. As tempting as it may be to go for them, the question is are they any good?
In this post, I’m going to go over Rev9 in detail as well as their coilovers to answer this question.
About Rev9 the Company
Rev9 Power is part of Fatboy Garage Motorsport, INC. They sell a wide range of performance parts from coilovers to turbos, intercoolers, exhausts and more. They are based in California, but the parts is made in China. They also make the Godspeed brand of coilovers.
Aside from that, there’s not a lot more information to be found on the company. Unfortunately, that’s pretty typical when it comes to budget coilover brands.
Let’s take a look at the coilovers Rev9 sell.
Rev9 Hyper-Street ONE Coilovers
The Hyper-Street ONE are Rev9’s entry level coilovers and have a decent set of features for an entry-level kit that sells for under $600.
They are designed primarily as daily driving coilovers and feature a monotube shock with 16-level adjustable dampening.
The ride height adjustment is done by the shock body, meaning you adjust the ride height independent of spring preload and have full suspension travel at all heights. They give you a lowering range of about 1-3 inches (25-75mm) lower than stock, depending on the vehicle.
They also come with Pillow-Ball top mounts on applicable vehicles, but they are not camber adjustable.
Now, the shock bodies are made of steel, so keep this in mind if you live in an areas with harsh weather, as they are far more likely to rust and seize the adjustment collars.
They have a 1 year limited warranty, however that only applies to customers in the USA, to the original purchaser and if bought directly from Rev9 or from authorized retailers or resellers, and comes with a long list of exclusions (check out the Rev9 website for more details).
Rev9 Hyper-Street II Coilovers
The Hyper-Street II coilovers are meant to be a set up from the Hyper Street ONE’s and feature 32-level dampening adjustment as well as larger monotube shocks which have a larger capacity for gas and oil, in order to improve ride comfort.
The shock bodies on these are made from “Full Steel Alloy” with little other specific details as to what exactly that is.
Otherwise, they have largely the same features as the Hyper-Street ONE’s, including height adjustment done by the shock body and also coming with Pillow-Ball top mounts on applicable vehicles which are not camber adjustable.
Rev9 Hyper-Street 3 Coilovers
The Hyper-Street 3’s are the premium coilover option from Rev9 and feature inverted monotube shocks (still 32-level adjustable) which are meant to enhance overall ride comfort, according to Rev9 (only on the fronts – rears are normal upright shock design).
They also come with camber adjustable pillow-ball top mounts on applicable vehicles (fronts only), and all the other features of the Hyper-Street II’s such as height adjustment by the shock body.
So, Are Rev9 Coilovers Good?
After scouring the internet, the consensus seems to be hit or miss. There are people who have them and like them, but there are numerous accounts of people having issues with these coilovers.
One of the common problems is that the dampers are either too long or too short, resulting in either a very high or very low ride height that couldn’t be solved through adjusting.
Others had issues with the strut mounts not fitting correctly and being unable to adjust the camber as a result, or brake line brackets not being in the correct position etc.
There were also numerous reports of bad packaging for shipment, with the suspension turning up with scuffs and paint chips right out of the box.
The feedback on Rev9’s customer service was also hit or miss, with some reporting them being good to deal with and that they sent out replacement parts to solve the problem (in the cases of the shock height issue). Others reported that it was very hard to get a hold of them and that they weren’t interested in solving the problem.
Another recurring problem seems to be the shocks blowing out after a short period of time (6 months) – this is something that Rev9 didn’t seem to want to cover with the warranty in the examples I found.
In terms of ride quality, many people report a surprisingly comfortable ride, and much improved handling over stock suspension. Once the dampening adjustability and spring-preload settings are set correctly, it seems that these coilovers actually ride pretty good.
Should you Buy Rev9 Coilovers?
Personally, I wouldn’t. I haven’t been very impressed with what I’ve seen so far. From the lack of company information, to the warranty terms that have a long list of exclusions and don’t cover shipping or installation costs, the conflicting information on their own website, and the numerous reports of poor quality, premature failures and design flaws, it just looks like too big of a risk.
Overall it seems that you are rolling the dice on these coilovers, and you may end up with a good set like some people did, but you also may end up having to mess around because they don’t fit like they should or have some other problem. And the chances of the shocks failing soon is also fairly high.
However, if you really want to get some Rev9s, you can get them here for the best price I have found (just don’t say I didn’t warn you):

What I Would Recommend Instead
If you are looking to get coilovers in this price range, I would highly recommend checking out TEIN Flex Z‘s.
These coilovers are only $200-300 more than the Rev9s but have an excellent reputation and are a very high quality kit.
TEIN is a well known coilover company who make high quality products, and in the case of the Flex Z’s, are made at their facility on Yokohama, Japan.
These coilovers give you ride height adjustment by the shock body, ensuring you get full suspension travel at all ride heights, and will lower your car up to 5 inches depending on the model.
As these are designed primarily as a street setup, the feature twin tube dampers which are tuned for street comfort, and give you 16 levels of dampening adjustment. They also feature damper oil which is designed to withstand intensive driving and extreme temperatures, making them suitable for occasional track day use.
The dampers are also designed as replaceable inserts meaning you don’t need to send the coilovers in for a rebuild, you just order the replacement damper inserts and swap them in. TEIN will also custom valve the replacement dampers for you if you need it done.
They come with everything you need for a street setup including camber adjustable strut mounts on applicable models, TEIN’s special no sag springs, TEIN’s patented powder coat and ZT coating for maximum corrosion protection and more.
For only a couple hundred dollars more, you will be getting a significantly better coilover kit that has proven to be a good choice and will perform well both on the street and track. If you ask me, you should definitely go for the TEIN’s.

Some Q&A regarding Rev9 coilovers:
Where Are Rev9 Coilovers Made?
Rev9 coilovers are made in China.
How Do You Adjust Preload on Rev9 Coilovers?
Spring preload on Rev9 coilovers is adjusted by winding the spring perch collars up or down against the spring. The spring preload should be adjusted to the specifications supplied by Rev9.
How Do You Adjust the Height on Rev9 Coilovers?
Ride height on the Rev9 coilovers is adjusted by the shock body, not the spring perch. You raise or lower the height by loosening the collar at the bottom of the shock body and winding the shock body up or down, then tightening the locking collar.

I have a JDM Honda Accord SiR-T chassis code is CF4. Do you know which model accord or prelude as I been told would match my car for coil overs?
Please note my model Accord never made it to the North American Market. You can Google Honda Torneo Euro R to get an idea what mine would like like and specs.
Hey Abdul,
I’m not too familiar with those models of Honda so I don’t want to give you an answer and you end up buying the wrong coilovers because of me. Sorry I can’t help. Probably best to speak to the coilover manufacturer themselves and see which model they think is right.
