Jeep® Wrangler JL Product Lineup From Holley Family of Brands Continues to Expand

10 min read

Holley’s family of brands has all the right products to beef up your ’18-’19 Jeep JL for the trail. High performance air-intakes, axle-back and cat-back exhaust systems, tuners, auxiliary lighting, stronger differential covers, and more are available at the click of a button. Read on to learn how to get your JL ready for the trails this season!


Five Hooker BlackHeart exhaust systems are available – four axle-back systems and one cat-back. The axle-back exhausts come in four different versions: high-clearance with a muffler, high-clearance without a muffler, high-tuck with a muffler, and high-tuck without a muffler. They're up to 20 percent lighter than OE systems and all five (including the cat-back design) offer gains of up to 4 horsepower and 7 foot-pounds of torque and feature mandrel-bent 2.5-inch tubing, stainless steel construction, and factory mounting points for a hassle-free installation.


B&M produces four unique products for JLs – a transfer-case handle, a SportShifter, and differential covers for both the front and the rear. The black-anodized billet aluminum transfer-case features an extended handle that allows for easy reach without having to awkwardly reach down for it and provides extra leverage that makes it easy to shift. The SportShifter is perfect for 6-speed manual transmissions and made of stainless steel with an anodized aluminum pivot that reduces the throw by 18 percent for a shorter, more positive feel when shifting gears. Built just for new Dana 44 AdvanTek differentials, the nodular-iron differential covers resist the rocks and ruts that can ruin lesser covers and come with durable black powder-coated clear-gloss finish and rugged reinforcing ribs for extra strength and durability.


Flowmaster Delta Force performance air intakes feature a custom-molded black XLPE high-flow intake tube, black-anodized fittings, reinforced silicone couplers, and stainless steel hardware. A large-diameter conical dry-synthetic air-filter element, custom-fit black-powder-coated air dam and soft bumpers that prevent any metal-to-metal contact complete the package. To extend their life, they can be shaken and lightly blown out with air.


Flowmaster produces numerous exhaust products just for JLs, including American Thunder cat-back systems, Outlaw axle-back systems, Force II axle-back systems. The American Thunder series delivers a moderate to aggressive exterior and mild interior exhaust tone features all mandrel-bent stainless tubing and is designed for an easy-fit hassle-free installation. The Outlaw and Force II series provides all the benefits of the American Thunder line with polished stainless tips and also feature stainless steel construction and all the hardware for a simple at-home installation.


iNTECH Cold Air Intakes deliver almost 25 additional horsepower and 22 foot-pounds of extra torque at the rear wheels across a broad power band. They feature a special Slip-Seal housing/filter-tube interface for a seamless installation that eliminates the need for hose clamps and adapters. The washable, reusable high-flow four-layer dry-air filter means you don't need filter oils that can set off check-engine lights and damage MAF sensors. A silicone Bellows-style coupler at the throttle-body connection allows the use of nitrous plates or throttle-body spacers without requiring you to modify the tube, and the conical filter is mounted vertically to guard against the dust, dirt, and mud that can accumulate during off-road use. Factory mounting locations and emission controls make for a hassle-free installation, and the housing design is styled to match the rest of the engine compartment for a stealthy appearance.


Superchip's DiabloSport makes the seemingly difficult task of tuning a Jeep® JL a breeze. The tuner is packed with exactly the features you want most, such as tire-size adjustment, TPMS options, idle RPM and start/stop-disable. Options include DiabloSport's industry-exclusive PKIT lineup, which includes an unlocked computer, and the popular Trinity 2 and inTune i3 tuners. Lower-cost options are inTune the i3 and Trinity 2 PCM Swap kits, which provide a seamless route to get your Jeep® tuned with absolutely no downtime whatsoever. The all-new TrailCal also offers monitoring, calibration, and control features without the hassle of modifying your vehicle. It allows you to calibrate for larger aftermarket tires and different gear ratio and previously was only available in the handheld Flashcal device. TrailDash2 features a slim new case design, a large five-color display, a higher-resolution screen, and one HDMI-style plug for power and linking EAS accessories.


Bright Earth light bars and cube lights illuminate any off-road experience. Universal in design but perfect for Jeep® Wrangler JLs, the light bars come in both straight and curved versions in sizes ranging from just 7-1/2 inches to as much as 54 inches wide and feature an extruded aluminum housing with LED spotlights in the middle and floodlights at each end. They include double-row LEDs and a waterproof housing, sealed wiring connector and universal mounting brackets. The cube lights provide 1,440 Lumens of light from six LEDs and are available individually or in sets of two. They come in both an 8-degree spotlight and 90-degree-floodlight beam pattern and feature a waterproof, dustproof housing and stainless mounting brackets and hardware.
