The front is a full mid-arm setup, the rear is a 3 link long arm conversion, and the combination is what Rock Krawler calls the best blend of on-road manners and off-road ability for this chassis. Pro Elite means billet 7075 aluminum lower control arms, CNC machined and service free, at the front and rear. The No Limits sway bar setup replaces the standard front sway bar disconnect kit.\u003c\/p\u003e\u003ch3\u003eWhat's in the kit\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e(2) front billet 7075 aluminum adjustable lower control arms, (2) front adjustable upper control arms and (2) rear billet 7075 aluminum lower long arms\u003c\/li\u003e\n\u003cli\u003e(2) rear lower control arms and a rear upper control arm\u003c\/li\u003e\n\u003cli\u003eRear long arm mount kit, rear upper frame mount, rear track bar mount, rear axle truss and (2) rear shock mounts\u003c\/li\u003e\n\u003cli\u003eFront and rear adjustable track bars\u003c\/li\u003e\n\u003cli\u003e\"No Limits\" front sway bar kit and (2) rear extended sway bar links\u003c\/li\u003e\n\u003cli\u003e(4) triple-rate coil springs and (4) spring correction seats (Comp coilover packages ship the rear pair only)\u003c\/li\u003e\n\u003cli\u003eRear brake line mount kit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhy this system\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFull mid-arm front end paired with a 3 link long arm rear conversion.\u003c\/li\u003e\n\u003cli\u003eBillet 7075 aluminum control arms, two up front and two long arms out back, CNC machined and service free.\u003c\/li\u003e\n\u003cli\u003eThe 3 link rear with a track bar removes the natural binding of the stock rear suspension, so the rear moves smoothly without jacking.\u003c\/li\u003e\n\u003cli\u003eX2 rear geometry gains 4.5 inches of ground clearance under the rear axle without giving up any rear shock travel, and the rear roll center is raised to help handling and cut down on side to side axle shifting off-road.\u003c\/li\u003e\n\u003cli\u003eAll of the control arms use Adventure Series joints, so they are maintenance free.\u003c\/li\u003e\n\u003cli\u003eTriple-rate coils that work together for a ride Rock Krawler says beats the OEM linear rate springs, with free length set for off-road articulation.

The front is a 2.625 inch RRD racing coilover with a remote reservoir (13 inches of shock travel, 14.4 inches of front axle travel) and the rear gets matching 2.625 inch RRD racing shocks with remote reservoirs. A good fit if you want coilover adjustability up front but still carry small loads or tow a small trailer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComp Coilover System - Stage 2:\u003c\/strong\u003e The Comp layout with Fast CD (compression damping) adjusters added to the front coilovers and the rear shocks, for even more tuning.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrail Runner Coilover System - Stage 1:\u003c\/strong\u003e 2.625 inch RRD racing coilovers with remote reservoirs at all four corners. It maximizes off-road ability and comes tuned for the street, but Rock Krawler cautions that rear coilovers do not handle changing loads well, so regular towing or heavy weight in the bed is not ideal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrail Runner Coilover System - Stage 2:\u003c\/strong\u003e The Trail Runner layout with Fast CD adjusters on the coilovers for the most tuning.

With full OEM fenders they recommend 37 or 38 inch tall tires, with trimmed or high lined fenders 40 inch tall tires, both with a 3 inch bump stop height, and backspacing of 4.5 inches for 37 inch tires or 3.5 inches for 40 inch tires.\u003c\/li\u003e\n\u003cli\u003eRock Krawler suggests dropping 1 inch of rear coil lift height if you are building with a spare delete, and going up 1 inch for an overland or heavily loaded rear.\u003c\/li\u003e\n\u003cli\u003eInstall: requires welding the rear long arm mounts, removing the OEM frame side upper and lower rear control arm mounts and the OEM axle side rear lower control arm and track bar mounts, and modifying the OEM rear shock mounts to weld on the raised rear upper shock mounts.\u003c\/li\u003e\n\u003cli\u003eRock Krawler recommends a new front C.V. driveshaft for any front shock with a maximum extended length over 29 inches, and limiting straps to avoid over-extending suspension components.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eRock Krawler lists lifetime warranty coverage on this system.\u003c\/p\u003e","brand":"Rock Krawler","offers":[{"title":"Base System - No Shocks","offer_id":45517395886146,"sku":"JL45TX2NLP-2","price":5598.99,"currency_code":"USD","in_stock":true},{"title":"Bilstein 5100 Shocks","offer_id":45517395918914,"sku":"JL45TX2NLP-2B51","price":6240.99,"currency_code":"USD","in_stock":true},{"title":"Stage 1 - RRD 2.25 IFP Shocks","offer_id":45517395951682,"sku":"JL45TX2NLP-2S1","price":6852.99,"currency_code":"USD","in_stock":true},{"title":"Comp Coilover System - Stage 1","offer_id":45517395984450,"sku":"JL45TX2NLP-2CS","price":10254.99,"currency_code":"USD","in_stock":true},{"title":"Comp Coilover System - Stage 2","offer_id":45517396017218,"sku":"JL45TX2NLP-2CS2","price":11114.99,"currency_code":"USD","in_stock":true},{"title":"Trail Runner Coilover System - Stage 1","offer_id":45517396049986,"sku":"JL45TX2NLP-2TR","price":11109.99,"currency_code":"USD","in_stock":true},{"title":"Trail Runner Coilover System - Stage 2","offer_id":45517396082754,"sku":"JL45TX2NLP-2TR2","price":11874.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1476\/5984\/files\/JL45TX2NLP-S1.THUMB__87294.1750100256.webp?v=1791653330","url":"https:\/\/www.skinnypedalracing.com\/products\/rock-krawler-4-5-inch-t-rex-pro-elite-no-limits-hybrid-jeep-wrangler-jl-2-door","provider":"Skinny Pedal Racing","version":"1.0","type":"link"}
