FAQ:
Why bolt-in?
There is nothing wrong with a race ready, NHRA/JeepSpeed/NASCAR/WRC/F1 approved, sonic tested, x-ray verified, high velocity impact tested, fully welded cage custom designed for your individual race vehicle. Except of course, the unaffordable price, massive vehicle disassembly, user unfriendly nature, and it goes without saying - non DIY install requirements. Those are just a few of the reasons we prefer our bolt-in method. Our RH4x4 bolt-in ready cage eliminates the headaches of a fully welded in cage for the wheeler from all walks of life yet provides an unbelievably strong, proven cage design.

Why not replace the entire vehicle cage?
The answer is simple: crumple zones. The section of OEM cage that runs along the top of your doors from front to back has factory designed and DOT approved crumple zones that are designed to absorb impact during a roll over or collision. Without theses absorption sections your cage would "sheer" and not provide any protection. If we were to replace those with solid steel tubes, removing any absorption during roll over, your safety would be compromised. By retaining those crumple zones we can maximize their attributes and provide a more secure and safe system.

Is any welding required?
No. Our bolt-in method allow for a DIY no-weld, truly bolt-in install.

How does this affect my seat recline feature?
You will have 3-4 clicks back depending on OEM seat cover thickness option.

Do my rear seats still fold down?
Yes.

How far back will my seats slide?
All the way back. No slide is lost.

What finish is available?
Our cage systems ship in a raw, bare metal finish. This prevents potential shipping damage but more importantly allows you the freedom to select your own color locally. Continue a color theme into your cabin for a more unique, your Jeep look!

Where is this mount made?
This product, like all RH4x4 parts, was designed, developed, tested, manufactured, and if applicable, powder coated, and shipped in the USA. And we don't mean the 75% legal standard to be able to say Made in USA. We are 100% Made in the United States of America!

Solid Product
To be fair and honest, I really did not need a harness bar. But a seat project "gone SOUTH"! Kind of led me down that path.As for the product itself... it is as advertised! Very well made & designed. In theory, install is easy... put it in place, mark and drill some bolt holes and bolt it in! In reality & depending on your jeep? This can be a booger to get in place! In my case it was a tight f

Great Safety Product - JKU Front Seat Harness Bar
I purchased the JKU Front Seat Harness Bar to install four point harnesses in my Jeep. The installation was very easy and they look amazing! I can't wait to try them out on the trail.

This product fit perfectly. Welds look great. This is just what I needed for harnesses without the added expense of an entire roll cage.
