So, you’ve just taken delivery of your brand new Jeep® JT Gladiator. Spotless paint gleaming in the sunlight, you ponder mods and upgrades.
One of the JT Gladiator’s greatest strengths is its massive aftermarket presence. However, this sizable catalog sparks some questions, like which products best suit your Gladiator and which modifications come first.
Fortunately, RealTruck’s team of experts has done the hard work for you. This guide outlines the top mods and upgrades for the Jeep JT Gladiator, bolstering aesthetics, off-road performance, ride quality, and more. Read on for a comprehensive blueprint to take your JT from a bone-stock pickup to a well-rounded rig.
First, let’s cover one of the most popular modifications for any four-wheel-drive Jeep platform—suspension modifications, like lifts and leveling kits. Modified suspension systems offer countless benefits over your JT’s factory equipment, including enhanced aesthetics, improved ground clearance, additional articulation, and enhanced performance in off-road conditions.
Lift kits and leveling kits come in several different configurations. For instance, leveling kits may consist of a mere spacer—a composite, aluminum, or fabricated steel spacer installed above the factory coil/strut assembly—or a complete replacement front coil/coilover. Lift kits are no different, offered in coilover, long arm, and standard configurations. Each offers different aesthetics and performance levels—which is right for you?
To help ease your decision, check out the Best Lift Kits for the Jeep Gladiator on RealSource.
Regarding lift kits and leveling kits, a modest standard lift kit is arguably the best bang-for-your-buck suspension system for the Jeep Gladiator. The Superlift 4” Standard Lift Kit is one such product, offering a taller ride height, improved off-road performance, and enhanced ground and fender clearances.
Superlift is a reputable, US-based suspension manufacturer renowned for its reliable construction, exceptional quality, and affordable price points. It’s also a RealTruck brand, meaning any Superlift product comes backed by RealTruck’s industry-leading customer service and unbeatable warranties.
Features:
Complete front and rear lift kit

After installing a lift kit on your JT, we recommend filling out the fenders with fresh wheels and tires. Wheels, also called rims, can make or break a vehicle. They’re the finishing touch that makes a build unique, ensuring your JT stands out from every other Jeeper on the road. However, the benefits aren’t limited to aesthetics.
Aftermarket wheels can also impact performance, as they're offered in various configurations outside factory specifications. These include different sizing (diameter, width, offset), materials, and finishes. Different sizes can help dial in your Gladiator’s fitment, promoting rub-free clearance for oversized tires. Furthermore, alternative materials and finishes can help to impact a wheel’s overall weight, durability, and more.
Accompanying aftermarket wheels are aftermarket tires, which significantly impact looks and performance. Not only do oversized off-road tires provide an aggressive appearance, but they also enhance performance. Whether your Jeep is a daily-driven rig, weekend wheeler, or avid off-roader, RealTruck’s assortment of all-terrain, hybrid-terrain, and mud-terrain tires ensure unmatched performance in any terrain.
Check out the Best Jeep Gladiator Wheels and Tires for additional information on sizing, tire types, and our experts’ top-recommended products.

With a lift kit and oversized tires installed, you’ll likely notice the massive increase in ride height—especially while attempting to climb into the cab. Rather than twisting an ankle or throwing out your back doing athletic leaps and dismounts, consider outfitting your Gladiator with premium side steps from RealTruck.
Side steps, including nerf bars and running boards, lower you and your passengers’ access point into the cab. These accessories also provide a wide, stable, non-slip foothold, ensuring safe entry in all conditions.
Side steps come in countless configurations, ranging from mounting style to material and finish. Check out our comprehensive Jeep Gladiator Side Step Guide for a thorough breakdown.

The addition of low-offset wheels and oversized tires often results in a lack of tire coverage. This condition poses several downsides, like exposing your Gladiator to rock chips and tire sling. Insufficient tire coverage is also a punishable offense in most states, warranting a citation.

Mud flaps and splash guards have just as much variance, ranging from oversized hitch-mounted flaps and universal rubber flaps to sleek, vehicle-specific splash guards.

At its core, the Jeep Gladiator is a pickup truck. And like any good pickup, it deserves a well-equipped bed, complete with a durable bed liner, cargo-bolstering rack system, and more.

Lastly, let’s talk about performance. While the Gladiator’s 3.6L Pentastar V6 isn’t a slouch, it won’t throw you back in your seat—and that's on stock suspension and tires. Once you’ve added beefy steel bumpers, sliders, bed racks, and oversized tires, the once-sufficient powertrain falls on its face. Fortunately, RealTruck carries a wide selection of performance products to boost power and efficiency.
If airflow is a concern, check out our selection of high-flow air intakes. Just as important as an engine’s fresh air intake is its exhaling of exhaust gasses, and performance exhaust systems promote just that. Top these mods off with a premium tuner or programmer to optimize results, recouping some lost power.
