Lifting a JL Isn't Just About Bolting on Shocks
I've spent the better part of a decade messing with Wrangler platforms, and the JL is no different from the JK in one key way: people buy parts before they figure out what they actually need. You will end up with a budget that blew past your original estimate and a vehicle that handles worse than stock. That's normal. It's also fixable if you approach it with some structure instead of impulse orders. The reason most people bounce around forums and YouTube channels is because the customization space for the JL has exploded since 2018. Every manufacturer from TeraFlex to Rough Country to OME has a product line for it now, and the compatibility matrix is messier than the JK era. Axle types matter more than you'd think. If you have a Rubicon with the Dana 44 front and Dana 60 rear, your suspension, track bar, and steering geometry decisions are completely different from someone running the softer Dana 30 front axle. Buying parts without confirming your axle code first is the single most common mistake I see. It wastes money and it wastes weekends. Here's how I actually work through a JL build now. I start with the end use. Rock crawling, overlanding, daily driving with an ego boost—these three categories demand entirely different setups and your first decision point should be honest about which one you're solving for. A 3-inch lift with a bump steer kit makes sense for high-clearance trail use. It's a nightmare for on-road manners. A half-inch level kit with new shocks is plenty for most people who just want a 33-inch tire and improved approach angles. Understanding that distinction upfront saves you from buying a $3,000 suspension kit you don't need.
Steering Geometry Is Where Builds Go Wrong
The JL's steering box lives in a different position than the JK, and that changes everything about how tie rod geometry behaves when you lift the front end. Stock height, the Pitman arm, the drag link, and the tie rod are roughly in parallel. Lift it 2 inches and suddenly you're introducing arc motion that causes bump steer. Not a little bump steer. Enough that the wheel will twitch in your hands over center bumps at highway speeds. I ran into this on a friend's 2021 JL Sahara with a 2.5-inch lift and no correction components. He couldn't drive it above 55 mph without fighting the wheel. The fix wasn't another shock or a heavier spring. It was a drop pitman arm from Advanced Off Road combined with an adjustable drag link and re-geared rack. Total cost around $600 in parts, about four hours of shop time. Without those pieces, the lift itself was creating more problems than it solved. If you're doing anything over a 2-inch lift, budget for steering correction as a non-negotiable line item. Don't treat it as an add-on you can skip if the budget gets tight. It's not optional at that point. It's the difference between a drivable truck and a hand-cramping paperweight.
Tire Size and What It Actually Costs
Everyone wants 35s. Most people who put 35s on a stock JL regret it within six months. The engine is a 3.6-liter Pentastar with decent power but nowhere near enough torque to spin large tires efficiently without modification. You'll feel the power loss immediately. Throttle response drops. Passing speeds become anxiety-inducing. Fuel economy drops into the low teens if you were getting mid-teens before. Going from 33 to 35 inches on a stock setup requires a spacer lift at minimum, new track bar brackets, and often an extended brake line. It rarely goes any smoother than that. The Rubicon's 3.73 gears eat 35s better than the Sport or Sahara with 3.45s. If you're running the shorter gearing and going to 35s, a re-gear is coming whether you want it or not. That's $800 to $1,200 in parts and labor depending on whether you do it yourself. The practical sweet spot for a street-driven JL with minimal modification is a 33-inch tire. You get the look, you clear the fenders at stock height with maybe a touch of trimming, and you don't destroy your powertrain or your MPG. If you want to go bigger, plan for the cascade of supporting modifications. They always come.

Suspension Choices That Actually Make Sense
Long-arm setups like the TeraFlex 3.0 or King long-arm kits solve real geometry problems. They move the pinion angle and instant center points to reduce squat under acceleration and dive under braking. They also cost $2,500 to $4,000 alone. For most JL owners, a quality coil-over-shock combo from OME or Iron Recovery with a proper track bar correction bracket gets you 80 percent of the performance at 30 percent of the price. I run a set of OME 889s with Bilstein 5100s on my personal 2020 JL Unlimited. Three inches of lift, no long-arm kit, no fancy radius arm adjusters. It clears 35s with minor fender trimming. The ride quality is solid on pavement and it handles moderate trail work without buckling. Was it the most exciting build in the parking lot? No. Did it work? Yes. For 99 percent of people asking about customization, that's the answer they're looking for.
The Downloadable Build Tracker
I put together a practical tracking spreadsheet that covers the entire customization sequence for a JL. It walks you through suspension decisions, tire fitment calculations, steering geometry requirements, and the supporting mods that everyone forgets until they're already halfway through the build and stuck. It includes gear ratio calculators so you can see exactly what math says your transmission and transfer case will live with. You can download it from the guide page linked below. The spreadsheet is free. It's not a sales funnel. It's something I wish I'd had before I spent $4,000 on a suspension kit that didn't account for my axle configuration. Use it. Fill it out before you order a single bolt.
What This Approach Won't Fix
No amount of customization turns a Wrangler into a sports car. The JL has better ride quality than previous generations, but it's still a body-on-frame truck with solid axles and a wheelbase that makes parking lots feel like obstacle courses. If your goal is cornering performance, you're fighting physics no matter what you spend. Suspension upgrades improve capability, not agility. That distinction matters when you're deciding what to spend money on. Similarly, aftermarket exhaust systems on the Pentastar are largely cosmetic. You'll get a slightly louder sound and maybe two horsepower at best. Save your money unless you specifically want the noise. Same thing with underbody lighting. It does nothing for the vehicle except make it louder visually at night. Those are the categories where the aftermarket preys on impulse buyers, and they're easy targets if you're not careful. The guide I put together covers all of this and more. It doesn't push any particular brand or affiliate link. It's just a straightforward breakdown of what works, what doesn't, and what you'll regret skipping until it's too late. If you're starting a JL build, read through it first. Then fill out the tracker. Then order parts.
