Key Differences Between ZBroz And Shock Therapy
In all honesty, both of them are practically the same. So if you’re looking for big differentiating factors, you won’t find them.
If you really want to compare ZBroz and Shock Therapy, you’ll have to look for more subtle differences.
Build and ride quality, durability, longevity, and price are the major differences between ZBroz and Shock Therapy.
Let’s see how these work out in both brands.
- Build And Ride Quality
There isn’t much of a difference in their builds.
ZBroz shocks don’t have the crossover ring dividers for softer initial rates so the ride quality is slightly less smooth.
Shock Therapy has a ring divider so you get a smoother ride.
The crossover ring is the biggest difference in shock build between these two brands.
ZBroz not having the crossover ring means the initial rate is going to be harder.
And when you’re going slow, the full pressure will get on the main spring. This won’t make your ride quality horrendous, but it will definitely make it less smooth.
Shock Therapy got the assignment right. They added the crossover rig divider which makes the rides smoother. But it will also give you some rubbing issues.
So you can’t have it all with Shock Therapy, it is either a smooth ride or no rubbing.

- Durability And Longevity
These are far more important factors in the long run than people give them credit for. ZBroz wears down slower and lasts longer. Shock Therapy wears off faster so it lasts for a shorter time.
ZBroz might have sacrificed extra smoothness by ditching the crossover ring, but it dodged a bullet with the rubbing issue too.
Since it doesn’t have any plastic slider to deal with, it doesn’t wear off too fast. So you can get solid performance for a pretty long time from them.
Shock Therapy went slightly off with this one. The plastic slider wears off the springs pretty fast, and the ring also has a bad case of rubbing on the springs.
Overall, the springs last for much shorter than ZBroz.
- Price
The difference isn’t very big in pricing for ZBroz and Shock Therapy, but it is a difference nonetheless. ZBroz shocks are slightly more expensive than Shock Therapy.
It starts from $599.00 and can go up to $995.00 depending on what kit you’re getting.
Shock Therapy on the other hand is slightly cheaper. The price starts from $599.60 and can go up to $919.60 depending on the kit.
Note that all mentioned prices are excluding shipping and can change depending on the platform.
Which One Should You Go With?
This is where things get tricky. As you know now, both Zbroz and Shock Therapy are really good in terms of quality.
Both have a solid reputation regarding their performance output too.
So they’re practically twins, which makes it hard to compare them.
And this is why picking one of them is harder than you’d think.
But that doesn’t mean you’ll have to be stuck midway through.
You can most definitely choose, the final decision will come down to your personal preference.
But if you want an objective approach, you’ll have to look beyond the surface and focus on factors like longevity.
If you’re looking for something that will last long and don’t mind your ride being slightly less smooth, Zbroz is a good option.
The lack of crossover rings means your ride will be slightly rocky still, but it also means the springs won’t wear off too fast. Plus Zbroz doe not have rubbing issues either.
The only con of Zbroz is the price tag. Both brands have similar prices, but Zbroz is a little more expensive. If you can spare the budget, it is a solid option.
If you’re looking for smooth rides and don’t care about rubbing issues, Shock Therapy springs are very hard to beat. You get smoother rides and it comes at an affordable price. And they’re easily available too.
The biggest con of Shock Therapy is the rubbing. The springs look pretty bad compared to Zbroz even after a short stint of 6 months.
Plus the plastic slider seems to wear them off faster. If you don’t mind that, Shock Therapy is your best bet.
Overall, Shock Therapy is the better option if you want smoother rides. But if you’re looking for more durable options, Zbroz is as good as it gets.
