Say hello to J-Rated. A visual terrain scale and collection of suspension systems that take the guesswork out of building your Jeep’s chassis. It’s like asking a JKS suspension tech to join you on your next Jeep adventure. They could ride along and evaluate your Jeep’s performance. With that knowledge, that same JKS rep could point you towards the ideal lift kit for the way you drive your Jeep. JKS has done just that its new J-Rated Terrain Scale and complete suspension packages.

The team at JKS has been testing, driving, wheeling and, in general, “adventuring” our Jeeps for years. We’ve been hanging out with you on the same trails, at the same events and riding along with our customers. The JKS testing team has a motto: Driven, never trailered.  They refuse to put their Jeeps on a trailer and drag them to an adventure. From Michigan to Moab or Michigan to the Rubicon Trail, JKS has probably been there, had a blast and driven home.

The sum total of JKS Manufacturing’s on and off-road experience has been translated into a range of suspension systems designed for every style and usage of Jeeper imaginable. The J-Rated terrain scale compares the performance of suspension across a wide variety of terrains. JKS focuses on 4 main categories that challenge your suspension in different ways. The ratings are based on the performance of each category, but also include any compromises that might affect one of the other categories.

The J-Rating Categories

ROAD J-RATING: “How good is your suspension on-road?”  Often overlooked by many enthusiasts, JKS has mastered the art of maintaining on-road manners while improving off road performance. Engineering systems that perform better-than-factory on road while improving benefits off-road is what a complete suspension system is all about! The JKS “Road” rating factors in ease of component maintenance, ride quality on traditional road surfaces and stability at highway speeds. A system with a high road rating is great for a daily driver that gets out on mild trails a few times a year. You and your Jeep can even explore some more difficult terrain from time to time.

TRAIL J-RATING: For such a small word, “Trail” casts a wide net of performance driving scenarios. Trail is what Jeepers spend most of our off-road time on. It’s the space between the obstacles and the backcountry where we overland. Trail driving encounters speeds up to 25mph (and sometimes faster) off road.  It’s the terrain that can make you embrace your suspension choice, or make you regret it. Small rocks, potholes, slight ruts and small ledges can test the “tune” on shocks and springs, and the life and performance of bushings and arms. Its were your buddies cheap, squeaky lift kit is driving him nuts. Systems with high Trail Ratings will also have good Road Ratings based on vehicle speed, however Trail Rated Systems also have more robust strength upgrades and improved wheel travel.

CRAWL J-RATING: JKS does not take the term “Crawl” lightly. This is where your Jeep encounters the big, nasty rocks, ledges and boulders. It’s the hardcore stuff that many of us dream about. This is where skill and experience meet geometry and wheel travel. It’s where we need big flex and the right combination of strong parts to work in unison. To earn a big Crawl J-Rating, a suspension system must make some compromises in other areas. If you and your Jeep play with rocks, those compromises are worthwhile.

BAJA J-RATING: This category might be the most fun type of driving to “test”. The word “Baja” brings thoughts of wide-open throttles and blasts through sand and dirt at speeds exceeding 25mph. The Baja category is for sand dune runners, desert lovers and anyone that likes to go fast in their Jeep. A high Baja J-rating mean that the suspension system includes serious shock absorbers. Valving must soak up movement, but also have the fluid capacity to stay cool and consistent for miles and miles of  action. Suspension geometry is key here. High speeds require careful engineering with respect to angles and handling. You get to focus on the trail and the fun rather than worrying about your suspension system.

When it comes to offroading, Sway Bar Disconnects are a time-honored tradition. They’re like a rite of passage. If you need to disconnect your sway bar end links, then you must be a serious Jeep nerd. While JKS Manufacturing did not invent the quick disconnect sway bar links, we did invent the Quicker Disconnect – A design that easily bolts onto your Jeep and makes off-road performance more obtainable. While often copied, JKS Quicker Disconnects are still the best solid sway bar end links you can buy for your Jeep. We’re proud of that design. At the same time, since we’re always looking for the next big idea.

JKS Manufacturing adds to its lineup of suspension upgrades for the Jeep Wrangler JL and Gladiator JT with new J-Flex front adjustable upper control arms. These front J-Flex uppers join the existing upper and lower control arms options giving you the ability to make significant improvements to the strength and performance over the stock control arms. These arms are constructed from high strength DOM tubing and feature robotically welded ends to ensure precision welds and strength. At the frame mount a forged end is threaded in allowing plenty of adjustability for use with with a wide range of ride heights from stock to 6" of lift. The forged ends allow 15 degrees of articulation in either direction and can be easily serviced at the grease fitting. These arms come fully assembled right out of the box finished in a gloss black powdercoat. Upgrade your JL/JT front upper control arms with JKS Manufacturing.

JKS Manufacturing launches the first of several Jspec lift systems for the new Jeep Gladiator JT, 3-3.5” J-Rated Systems allowing clearance for 35-37” tires. Engineered to maintain on-road comfort and handling while improving offroad capability, these new 3-3.5" J-Rated Systems build on JKS's legacy of innovative solutions building a true dual purpose platform ready to tackle your next off-road adventure or highway commute to and from the office.

Since the initial launch, the JKS Manufacturing’s Flex Connect has been a huge hit allowing Jeep owners to easily tune their vehicle’s handling characteristics for improved on and off-road use. The spring loaded sway bar link design gives Jeep owners the freedom to transform their factory sway bar into a tunable performance sway bar to better control body roll, smooth out rough terrain and improve wheel travel out on the trail all while catering to individual performance needs and driving styles.
