The right lift kit is a decisive factor between having a successful ride or messing up your vehicle while driving off-road.

If you want to avoid unnecessary damage, two of the brands you should consider are Rock Krawler and TeraFlex.

Both of those brands provide high-quality suspension systems that improve the car’s efficiency on and off the road.

That’s why today we’re discussing Rock Krawler vs. TeraFlex, and this article will give you the information needed to make the decision on which one to buy.

First, let’s review some of the top products from each brand. Then, in the following section, we’ll mention the main differences between the two. Let’s begin!

Rock Krawler vs Teraflex

Truthfully, both TeraFlex and Rock Krawler provide high-quality lifts for you to consider.

Of course, depending on your purposes, you may go for one or the other. Rock Krawler, for instance, has better high misalignment joints on control arms, while TeraFlex uses Clevite bushing like stock.

For 35’s and factory fenders, you’d do well going for the 3” Teraflex Kit. So, as you can see, it depends on the type of vehicle and your expectations.

How to Decide?

It’s a long debate. Rock Krawler often has better prices, sway bar links, and brake lines.

However, TeraFlex also has its benefits, such as better front track bar, optimal geometry correction, informative instructions, and incredible customer service if needed.

So, as you can see, each brand has its advantages and disadvantages.
Either way, everyone can agree TeraFlex, as well as Rock Krawler, are incredible brands.

Their products are top-notch, meaning you won’t go wrong with either one.

Rock Krawler provides well-designed suspension components that use every one of their features effectively.

From the triple-zone design to the durable parts, drivers can expect reliable performance from these products.

Ultimate Suspension

Rock Krawler rear coil springs allow drivers to experience driving as they want to. The triple-rate lift operation guarantees proper dampening power, which leads to better maneuverability overall.

No Unseating

Since preventing unseating at full droop is essential, the coil springs have three zones that tackle that issue. The light rate zone, the firm zone, and the soft zone, all of which combine well for better handling on and off-road.

High Compatibility

Due to their design, the suspension systems fit a variety of vehicles, whether they’re old or new.
