    Features & Details

    • Increases Driveshaft Clearance
    • CNC Precision Machined
    • DOM Steel Tubing
    • For use with most lift kits
    • Fits 2012-2018 Jeep Wrangler JK Models

    Simple Solution. Lifting your 2012-2018 JK may leave you in a dangerous position where your exhaust may interfere, or make contact with your front drive shaft at the cross over point. This could end in damages to your JK's OE drive shaft boot which could lead to even more serious driveline problems. Prevent unnecessary damages by adding JKS's Exhaust Extension Kit. A simple and easy solution, this kit lengthens your exhaust to create a safer distance between your stock driveshaft and exhaust tubing. This solution is far more economical than investing in a new driveshaft and installs in mere moments to get you ready for the trail.

    Easy Installation & Removal. Unlike some modifications that require cutting or drilling, this Exhaust Spacer Kit is fully reversible. It installs easily at your exhaust flange with the included hardware and can be just as easily removed, should you decide to alter your lift at a later date.

    Quality Construction. This kit is engineered for durability and reliable performance with no exhaust leaks. It features spacers that are CNC precision machined from DOM steel tubing for an exacted fit in your exhaust flare joints.

    Application. The JKS Exhaust Extension Kit is designed for installation on 2012-2018 Jeep Wrangler JK or JK Unlimited models where lifting requires additional exhaust to driveshaft clearance.

        do i need these if i get a aftermarket driveshaft?

        • Exhaust extensions are not require when you are just changing the driveshaft on your Wrangler. If you are adding a lift kit and changing the driveshaft then you will generally need a new exhaust extension.

        Do all the exhaust extension kits cause smog issues so you do not pass the smog test in California

        • Hello, these should not interfere with the C.A.R.B. laws in California. I would double check with your local municipality if you are looking to order the Rugged Ridge Exhaust Spacer Kit for a 2.5-Inch+ Lift.

            high quality product

            Well designed with quality materials. Was easy to install. Did give extra drive shaft clearance but still rubbed drive shaft boot while on lift. Have not did any extreme off road driving at this time. Hope will provide enough clearance as long as don't go full air born.

            Does the job

            I'm glad I had a neighbor twice my size and strength to help. He was pulling the exhaust pipes apart while I was trying to insert and align the new spacer. Once the pipes are apart, they do not want to naturally line up when the spacer is inserted. The right side was a little easier than the left side. Once we tightened the bolts, they came together, though not perfectly straight, but I do not think I have any gaps.

            Snug fit.

            Well, I wish this was a "One Wrench" install like the videos depict, but not in my case. Actual product is really nice and machined instead of form molded. I have the Magnaflow Catback exhaust and there was no sliding the y-pipe deeper into the socket of the cat unit. The port on the unit is belled to a certain depth so I had to remove my y-pipe to trim off about 2". For the life of me, I could not get both spacers to line up nice and flush. I suspect one of my exhaust headers is slightly tweaked inwards about .25". I tried moving the catback system around to gain clearance and alignment to no avail. I had a bit of clearance issue on the passenger down tube touching the cross brace; but a bit of grinding took care of that. Once installed, it does the job of giving a bit more clearance to the drive shaft with my 3" lift.

            Well made

            I selected this product because it has a more straight through design than some others on the market, thereby causing less turbulence / back-pressure within the exhaust system. The parts are machined impressively well and the bolts are threaded plenty for my installation. One issue of concern is that along with moving the crossover pipe back and out of the way, it also lowers it below the transmission cross-member on the passenger side. This in turn requires that a significant amount of spacers be added for clearance of my engine / transmission skid plate, which bolts to the cross-member and slants upward to the front. Nothing that can't be accommodated, and I'd rather have that than a damaged driveshaft. This would be the case with any manufacturer's extension on my setup. Just a heads up for those with similar components. This product is very well made and does the job perfectly.

            Easy install, and gets the exhaust out of the way of the front driveshaft. Gave me the clearance I needed!

            The Spacers are awesome, the hardware is adequate

            The spacers themselves are beautiful. They are machined steel and fit perfectly. Together they move the exhaust back as described. I knock one star off because the hardware is lackluster. The plain shank bolts aren't fully threaded, and I swear I could've tightened mine up a bit more if the thread was there. Particularly on the passenger side. My time to install was a lot more since my exhaust had some rust on exhaust flanges and no lift. The 15min time might apply to those that installed this on the dealership lot.

            They work

            These things do move the exhaust so that you do not damage the drive shaft. They work great for what they do. They are a bit of a pain to install (might have been easier if I was not on the ground or if I had help), but they move the exhaust out of the way and hopefully keep your drive shaft off the exhaust.
