Crucial Supporting Parts for Lifted JKs
Don't overlook the secondary components affected by a suspension lift. Installing these supporting parts during your initial build saves you a second teardown later:
- Exhaust Spacer Kits: Vital for 2012–2018 JKs to safely reroute the exhaust plumbing away from the front driveshaft at full droop.

- Factory Restorations: High-quality OEM-spec replacement steering links to refresh worn-out commuter rigs.
Jeep JK Axles, Lockers & Re-Gearing Packages
Proper differential gearing is critical to restoring power lost to larger tires. Rubicon models feature Dana 44 axles front and rear, while Sport and Sahara trims utilize a Dana 30 front axle paired with a Dana 44 rear axle. We stock specific gear sets and reinforcement kits for both configurations.
| Axle Type | Available Upgrades | Best For |
|---|---|---|
| Dana 30 (Front) | Low-pinion Sierra Gear ring & pinions (4.10 to 5.13), upgraded 3.73+ carriers, aftermarket lockers, and chromoly axle shafts. | Sport & Sahara builds running up to 35" tires. |
| Dana 44 (Front/Rear) | Heavy-duty axle trusses, upgraded differential covers, high-angle CV joint kits, and premium master install kits. | Rubicon models or heavily abused setups running 35"+ tires. |
- Axle Maintenance: Heavy-duty ball joints, rugged inner axle seals, and replacement U-joints to eliminate front-end play and keep gear oil sealed tight.
- Professional Installation: Re-gearing and locker installations require precise tolerances. Our Red Seal technicians handle all differential builds in-house.
Exterior Protection & Trail-Ready Armour
- High-Clearance Fenders: Rugged MetalCloak front and rear metal fenders to maximize tire clearance during deep suspension articulation.
- Body Armor: Heavy-duty rock rails with integrated flip-steps to guard your rocker panels while providing clean cabin access.
- Track Width: Spidertrax wheel spacers to prevent tire scrub on internal frame components at full lock.
- Highway Compliance: Quick-release removable mud flaps that pull out with a single pin for the trail and slide right back on for the highway.
Overlanding, Electronics & Camp Upgrades
- Speedometer Calibration: Advanced programmers and modules to recalibrate your computer for tire sizes up to 42" and gear ratios up to 5.38.
- Power Management: Programmable switch control systems to cleanly route power to auxiliary trail lighting, winches, and communication gear.
- Onboard Air Infrastructure: Custom single and twin air compressor mounting brackets paired with universal radio antenna mounts.

FAQs - We've Got Answers
What is the difference between a Jeep JK and a JKU?
The Jeep JK is the standard 2-door model, while the Jeep JKU (Wrangler Unlimited) is the 4-door variant. Both configurations were manufactured between 2007 and 2018. While most suspension, steering, and axle parts fit both variants, interior accessories, rock sliders, and soft tops are specific to either the 2-door or 4-door body style.
Do Jeep Wrangler JL parts fit a Jeep JK?
No, the vast majority of Jeep JL parts do not fit a Jeep JK. The newer JL platform uses an entirely different frame geometry, suspension layout, and electrical network. Aside from a few adaptable universal components like select bump stops or steering stabilizer cylinders, suspension and steering components are platform-specific. Always buy JK-designated parts for a 2007–2018 build.
Does a Jeep JK need re-gearing for bigger tires?
Yes. Installing larger tires increases rolling resistance and throws off your factory torque curves, leaving your Wrangler feeling sluggish on the highway and inefficient on gas. Re-gearing your differentials to a deeper ratio (such as 4.88 or 5.13) restores original factory acceleration, improves crawl ratios, and protects your transmission from overheating.
Does a Jeep JK need a speedometer recalibration after lifting or adding larger tires?
Yes. If you do not recalibrate the computer after changing your tire size or gear ratios, the automatic transmission will shift incorrectly and force the vehicle into an electronic "limp mode." Utilizing a digital programmer allows you to update the engine control module, correcting your speedometer readings and restoring proper factory transmission shift points.
Why do Jeep JK door hinges need replacement liners?
The factory metal door hinge bushings on the JK and JKU are notorious for corroding, oxidizing, and freezing over time, making it incredibly difficult to remove your doors for summer driving. Replacing them with high-quality aftermarket Delrin or premium composite liners ensures your doors slide off smoothly every single time.
