Jeep Wrangler Lift Kit & Modification Guide
Lifting your Jeep Wrangler is the fastest way to add capability and aggressive styling. But doing it wrong will ruin your daily drive and void your warranty. Learn how to choose the right Mopar lift kit, maintain suspension geometry, and build a Jeep that handles perfectly on Tennessee highways and backwoods trails.
The best overall modification for a daily-driven Jeep Wrangler is a 2-inch Jeep Performance Parts (JPP) lift kit combined with 35-inch tires. This specific Mopar setup provides significant ground clearance for trail riding while retaining the factory steering geometry, protecting your warranty, and maintaining a comfortable ride for everyday commuting around Middle Tennessee.
Mopar vs. Aftermarket: Protecting Your Investment
The internet is full of cheap aftermarket spacer lifts that promise a big stance for very little money. What those listings do not tell you is how those kits affect your driveline angles, shock travel, and track bar alignment. A poorly engineered lift results in "death wobble," rapid tire wear, and a harsh ride.
When you select a Jeep Performance Parts (JPP) lift kit through Gallatin CDJR, you are getting components engineered by the exact people who built your Wrangler. More importantly, when installed by our certified technicians, a Mopar lift preserves your factory powertrain warranty.
The JPP 2-Inch Lift Kit
This is the gold standard for most drivers. It includes specially tuned longer front control arms, Fox shocks (or specifically tuned Bilstein shocks on newer models), and coil springs designed to accommodate the extra weight of steel bumpers and larger tires. It allows clearance for 35-inch tires on Sport and Sahara models, and 37-inch tires on Rubicon models.
Going Above 2 Inches
If you want to push past a 2-inch lift, the vehicle's geometry changes drastically. You will need to start addressing custom driveshafts, track bar relocation brackets, and re-gearing the axles so the transmission continues to shift correctly. We only recommend this for dedicated rock-crawlers.
This Is Where Jeep Modifiers Go Wrong
They buy massive tires without re-gearing.
Bolting 37-inch tires onto a base Wrangler with standard axle gears will make the Jeep sluggish, destroy your fuel economy, and cause the automatic transmission to constantly hunt for the right gear on the highway.
They use cheap budget boosts.
Puck-style spacer lifts raise the body but do nothing for wheel travel or shock dampening. When you hit a pothole on a cheap lift, the whole cabin shudders. Real suspension lifts change the coils and shocks to handle the new center of gravity.
If you do this, expect this: if you buy a random aftermarket kit online and install it in your driveway, expect warranty denials on suspension components and a bouncy ride. If you consult Gallatin CDJR parts specialists and install Mopar JPP components, expect aggressive looks with reliable factory-grade driving dynamics.
If This Sounds Like You, Do This Next
You just want a tougher look for daily driving.
Avoid extreme lifts entirely. Order a factory 2-inch Mopar lift and pair it with high-quality 33-inch or 35-inch all-terrain tires. You will get the stance you want without sacrificing highway handling.

Do not buy a base model and immediately dump $10,000 into aftermarket parts. Shop for a Wrangler Rubicon or Willys first. Those trims come from the factory with upgraded axles, better clearance, and gearing built to handle larger tires straight off the lot.

Building a Jeep in Gallatin means you need versatility. It has to handle highway speeds toward Nashville during the week and navigate uneven, muddy trails on the weekend. The soil and terrain around Middle Tennessee differ from open desert crawling out west, which means suspension travel and proper mud-terrain or all-terrain tire selection are critical.
Our parts team understands the local environment. We do not just sell parts out of a catalog; we consult with you to build a rig that survives exactly where you plan to drive it.

Jeep Lift Kit FAQ
Will lifting my Jeep Wrangler void the warranty?
Installing a genuine Mopar Jeep Performance Parts (JPP) lift kit at an authorized CDJR dealership ensures your factory powertrain warranty remains intact. Modifying suspension with cheap aftermarket components can lead to warranty claim denials if the aftermarket part causes another component to fail.
What size tires can I fit with a 2-inch Mopar lift?
A 2-inch JPP lift will comfortably clear 35-inch tires on Sport and Sahara trims. If you have a Rubicon, the high-clearance factory fenders paired with a 2-inch lift allow you to run up to 37-inch tires, though re-gearing may be highly recommended at that size.
Do I need to re-gear my axles when I lift my Jeep?
It depends on the tire size you choose. If you jump straight from a 31-inch stock tire to a heavy 35-inch or 37-inch tire without changing axle ratios, the Jeep will feel sluggish and your transmission will shift poorly. Consult with our team before purchasing massive tires.
Is a spacer lift the same as a suspension lift?
No. A spacer lift merely inserts pucks above the factory springs to raise the body for larger tires. A proper suspension lift (like the JPP 2-inch) replaces coils, shocks, and control arms to provide real suspension articulation and a better ride quality.
