We weren't the first JL kit to be released, but we feel we have the best. Where others rushed their prototypes to market with little to no testing, we invested the time and effort to thoroughly test everything. The result is what we feel is the best kit in the industry, and there's no need to accept anything less.\u003cbr\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eIn late 2017 we started on coil spring and shock designs as we got small bits of information. In late January 2018, we received our first Rubicon and a Sport, this is when we got ready to get to work. With the Jeep JL being totally redesigned from the departing JK Wrangler, everything was different. Ride quality, handling, and suspension travel were greatly increased on the new JL Wrangler, but it also meant that nothing that was learned from the JK applied to the JL. It was our job to design a coil spring that would ride as good if not better, not lose any of the outstanding road handling manners, increase the lift height for larger tires and add more suspension travel. We knew the challenge ahead of us wasn’t going to be quick, nor was it going to be easy. We also spent countless man hours on the computer designing with 3-D modeling. Now with over a year in design and real-world testing, we feel we have designed and engineered one of our best kits yet.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eWe developed a dual rate progressive front and rear coil spring. These springs were started from scratch and are a totally different design and spring rate from the departing JK. This extensive development takes time and is costly to design and build. Beware of many manufacturers and their one-size-fits-all mentality by using springs that are designed for other applications. It's certainly cheaper to borrow designs from previous platforms, and it gets you to market more quickly, but that doesn't make it right. Rusty’s JL coils springs were developed corner-specific, meaning that every spring is different on each corner of the vehicle, just as built from the factory. Corner-specific springs mean you can be assured the ride height of the vehicle will be correct, with no cheesy offset spacers needed to keep the vehicle level or reduce spring bowing. The Rusty’s 3.75\" kit will give you the clearance on a Rubicon JL to fully flex it with 37-inch tires off road and not have any fender rub, no inner fender rub. You can also easily run a 40-inch tire but bump stops are recommended for vehicles going off road.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eKIT INCLUDES:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eFront Progressive Rate Coil Springs\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eRear Progressive Rate Coil Springs\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eAdjustable Front Upper Control Arms with Forged Flex Ends\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eYour choice of Adjustable Front Lower Control Arms with Forged Flex Ends or Forged Rubber Ends\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eYour choice of Adjustable Rear Upper Control Arms with Forged Flex Ends or Forged Rubber Ends\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eYour choice of Adjustable Rear Lower Control Arms with Forged Flex Ends or Forged Rubber Ends\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eAdjustable Front Track Bar\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eAdjustable Rear Track Bar\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eFront Track Bar Frame Mount Brace\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eFront and Rear Extended Sway Bar Links\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eFront Brake Line Extension Brackets\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eFront Upper and Lower Coil Spring Isolators\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eKEY FEATURES:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eProgressive Dual-Rate Coil Springs Front and Rear\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eCoils specifically developed from the JL, not borrowed from previous platform designs\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eMaintains factory ride quality while making room for a larger tire and wheel package\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eAdjustable upper and lower control arms with Forged Flex Joints front and rear for the ultimate in adjustability and flex\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eExtended front and rear sway bar links maintain factory sway bar functionality\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eAvailable shock absorbers are tuned to work with spring rate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan\u003e* There is much talk about a driveshaft being needed for this lift, we have ran many JL's with stock shafts and have had no wear problems, a lot of this depends on how you use the vehicle. Just as it would stock, if you wheel a lot and use the vehicle in harder off road trails and situations, it will wear the driveshaft faster and then you will need to replace and we suggest a aftermarket HD shaft. But is it necessary for you to replace the driveshafts to install this kit, no not at all. Rusty's also offers a complete line of aftermarket HD driveshafts when that time comes.  \u003c\/span\u003e\u003c\/p\u003e\n\u003cbr\u003e\u003cbr\u003e\n\u003ctable border=\"0\" width=\"200\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd align=\"center\"\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0107\/0402\/7744\/files\/RK-375A-JL_1af797e4-cc5c-45b1-bda2-0a202cb3818a.pdf?v=1687980911\" target=\"_blank\"\u003e \u003cimg border=\"0\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0107\/0402\/7744\/files\/icon-instructions.png?v=1650314080\" hspace=\"10\"\u003e \u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cdiv class=\"cz-embed-gallery cozy-gallery-lazy-load\" id=\"cz-embed-gallery49673\"\u003e\u003c!-- ALWAYS KEEP THIS EMPTY --\u003e\u003c\/div\u003e","brand":"Rusty's Off Road Products","offers":[{"title":"Adjustable Control Arms with Forged Rubber Ends (SKU: RC-CA211HC-JLJT \/ RC-CA421-JLJT \/ RC-CA212-JKJL \/ RC-CA222-JKJL) \/ No Shocks Supplied \/ 2018 -
