Tuners for Jeep JK – Guide For Owners!

Tuners for Jeep JK – Guide For Owners!

The 3rd generation Jeep Wrangler is the JK model that was introduced to the market in 2006. The JK was an evolutionary step in the Jeep design, and this design includes all the standards such as a separate body and frame, front and rear rigid live axles, a fold-flat windshield, and can be driven doorless. The Wrangler JK also gives you the part-time four-wheel drive systems, with high and low gearing choice.

There is also a four-door model, which comes with an extended wheelbase of 20” instead of 10”, at first it was laughed at, but the market turned on its head, and the four-door became a market success.

JK Aftermarket

Jeep decided to cater to the aftermarket taste and created the JK with the least expensive parts so that the enthusiastic owners would not be afraid to replace parts, and even support parts replacement. After all, what’s better? An expensive jeep where you think twice before changing something, or an inexpensive model that lets you go all LEGO over it?

The New JK Difference

Let’s start off with some facts; the new V6 delivers more power at a slightly higher rpm than the old 4.0L inline. This means that on the road your engine will turn at around 700 rpm faster than the inline. In 2012 Jeep introduced the 3.6 Penstar that delivers an extra 85 HP, better MPG, and higher torque than the JK predecessors.

The later Rubicon models come with a push-button sway-bar disconnect this give you better suspension articulation and a smoother off-road ride. Add to this the Front and rear lockers, and you and the new rocker guards are cruising with extreme comfort.

The 2 doors JK does come with an advantage over it’s larger 4 door brother, the lighter weight and short wheelbase makes it perfect for off-road performance, which it delivers much better than the 4 doors. The 2 doors also don’t tax the engine as much, and the SWB (short wheelbase) gives you a lower turn radius with a better break over angle. As such, the 2 doors JK will roll over tougher and rougher terrain better than the 4 doors.

On the flip side, the 4 door Unlimited is a much better road trip vehicle since it comes with longer wheel size, and while the 2 door can climb better, the 4 door has less chance of flipping over due to the longer wheelbase. Also, the Unlimited can tow much better.

So, what does this show us? It shows us that you need two jeeps! One for each application. Just kidding,

Pros and Cons of the Models

The JK Unlimited (JKU) has a longer wheelbase (LWB), so it has 4 doors and can tow 1,500 lbs more than the standard 2 doors. The Unlimited has a wider turning radius, so the advantage is for the JK with its SWB design making it much nimbler. The JKU is heavier, so it strains the same engine base as the JK with more need for power and torque.

JK Wrangler Rubicon

The Rubicon is the top JK model, what makes them special? Well, the come with Mopar accessories, off-road suspension, and a lot of nonstandard stock mods. The Rubicon is also 2.5” higher than the standard JK and JKU, and this is due to off-road accessories which include the springs, shocks, sway bars, links, wheels, tires, and armor.

What can be tuned?

Jeep tuners will let you calibrate every engine part and all electronic components for performance and comfort, just as any other tuner on the market. This includes Camshafts, Cold air intakes, Cylinder heads, Fuel injectors, Full exhaust systems and headers, Intake manifolds, Nitrous systems, Rear gear changes, Superchargers/Turbochargers, and Throttle bodies. As well windows, locks, alarms, etc.,

Custom, Canned and Dyno

There are three types of tunes available, these are:

  1. Canned: A generic preset tune that comes with the device.
  2. Custom: A specially written tune, either prepared by a company or made by a professional.
  3. Dyno: A shop prepared tune, where the tuner dials it in in real time.

Just to be sure, never buy a tune from an unknown source, and never tune by yourself. Custom tuning is for professionals that understand the nature of the entire operation; one change can destroy your performance, let alone an entire range of changes.

Tuning Variants

There are two variants for tuning; one is the use of chips, which come with preset tunes that you can employ at the flick of a switch. These are closed circuits, which means you cannot make custom adjustments. The second variant is Tuners, which come with open circuits that allow you to make custom changes to specific options.

Now let’s take a look at the five best tuners for Jeep JK models.
