JK Mods to Avoid

Having your car customized is one of the most effective ways to increase its performance. Modifications to the Jeep Wrangler JK can increase its performance in a variety of ways, particularly when used for off-roading.

Jeep Wrangler fans in general appreciate how modifiable the vehicles are because of how simple it is to make changes. You can personalise your Jeep Wrangler JK in a variety of ways by installing various upgrades and additions.

Many Jeep JK owners have made modifications to their vehicles that end up being ineffective or even dangerous. However, if you are not careful, certain alterations can endanger you, other motorists, and pedestrians.

If you are inexperienced or new to Jeep World, you may not know what to avoid, making the situation much more risky. The alterations that many JK owners have put into their vehicles are either inappropriate or unnecessary.

If you are new to vehicle modification and unaware of which mods to avoid for your Jeep, then this article will help you understand which JK mods you should avoid altogether.

1. Dupli-Color Vinyl for Painting

Many Jeep Wrangler owners are unhappy with the colours their vehicle came in and opt to repaint the exterior (doors, hood, dashboard, etc.) with duplicolor vinyl.

However, refinishing a car entails more than just covering up the old paint. It is a time-consuming process to remove the old paint by sanding and scuffing the body before applying the new colour. Failure to do so may result in the fresh paint not adhering well and requiring constant touch-ups.

Do not attempt to paint your own JK if you are inexperienced with auto detailing and painting. Take it to the local auto paint shop and have a pro do it instead.

2. Poor Quality Shocks

For any vehicle that will be driven off-road, high-quality shocks are a necessity. When you drive on an uneven surface, they experience a great deal of stress.

If you choose cheap shocks for your Jeep, they will quickly wear out and your driving will not be as smooth as you would like.

Invest in high-quality shocks when you modify your JK if you don’t want any trouble when driving. Even if you must pay more, they are worthwhile.

Avoid investing in cheap shocks that may stop working after a short time.

3. Cheap Bad Quality Aftermarket Exhaust

While a high-quality aftermarket exhaust is one of the best upgrades you can make to a Jeep JK, a low-quality exhaust will be the worst.

Aftermarket exhaust systems are acceptable if they make the Jeep’s rear end look more imposing or increase the vehicle’s volume.

Still, you should invest in a high-quality model. In other words, it might make your Jeep look tacky.

The majority of aftermarket exhaust systems are aesthetically pleasing, but they do little to improve the visual attractiveness of a 6-cylinder Jeep.

In any case, if you’re set on having an aftermarket exhaust put in your JK, go with a reputable brand rather than the cheapest option.

4. Mud Terrain Tires

For various road conditions, various tyre types are useful. Off-road is where mud terrain tyres really shine. They provide enhanced traction and are less likely to skid in sandy or muddy conditions.

This adjustment is entirely case-dependent. Your primary driving location should determine whether or not you need this.

If you plan on using your Jeep JK for off-roading and trail driving, then mud terrain tyres are a must-have accessory. Most tour drivers spend their time on paved roads, so they don’t need mud terrain tyres unless they specifically want them. Definitely not worth the price tag.

You should change to all-terrain tyres instead. They perform admirably on the street and can be driven off-road with only moderate difficulty.

5. Upgrade Wheels From 15 Inch To 16-17 Inch

Larger wheels boost your vehicle’s ground clearance. This can affect off-roading on rough terrain. Even a couple of inches can shield your vehicle’s underbelly from pebbles and bumps.

Many drivers receive new tyres. JK Jeeps have 15-inch tyres. Most drivers get 16- or 17-inch wheels.

Bigger tyres only help on rough terrain with jutting rocks. In most circumstances, 15-inch Jeep tyres will provide appropriate ground clearance. On sand or mud, size doesn’t matter much.

To fit bigger wheels, you’ll need bigger tyres. This is pricey and not recommended unless you’re hiking rugged, hilly paths.

6. Tuffy Overhead Console

Most people cross-country tour in jeeps. Since you’ll be travelling, purchase a Tuffy overhead console for storage, security and communications.

This mod is bolt-on only. To put the overhead unit on your JK, drill holes. Most drivers like greater storage until they realise the price. Installation costs $270 to $500. DIY is cheaper, but you may make mistakes, so hire a pro.

The change isn’t horrible, though. It’s lovely and functional once attached. Cost-effective? Nope. If you want more storage in your JK, modify the trunk.
