Kei Truck Lift Kit: Tools, Tips, and Mistakes to Avoid

Kei trucks—Japan’s tough, compact workhorses—are becoming increasingly popular around the world for their versatility, affordability, and off-road potential. Whether you're using one for farm work, construction, or turning it into a weekend trail toy, lifting your Kei truck is one of the best modifications you can make. But before you jack up your mini truck and start turning wrenches, you need to know what you’re doing. Suspension work is no joke. Doing it right means a safer, more capable truck. Doing it wrong? It could mean poor handling, premature part wear, or even dangerous driving conditions. In this guide, we’ll walk you through the essential tools, pro installation tips, and common mistakes to avoid when installing a lift kit on your Kei truck.
🧰 Tools You’ll Need for the Job Before you get started, make sure you have all the tools you'll need. Missing one halfway through can quickly turn your DIY dream into a headache. Basic Tools: Jack and Jack Stands: Use a hydraulic floor jack rated for at least 2 tons, and always support your vehicle with high-quality jack stands. Socket Set (Metric): Kei trucks use metric hardware—ensure you have a full set. Wrenches (Metric): Combination wrenches can be essential for tight spots. Torque Wrench: Never guess bolt tightness—over-tightening can strip threads; under-tightening can cause failure. Breaker Bar or Impact Wrench: To remove stubborn or rusted bolts. Spring Compressor: If your lift kit replaces coil springs, you’ll need one. Never attempt to remove coil springs without one. Pry Bar: Helpful for lining up suspension parts during reassembly. Penetrating Oil (e.g., WD-40): Use liberally on rusted bolts before you begin. Measuring Tape: To measure before/after ride height and wheel alignment. Optional but Useful: Rubber Mallet: For gentle persuasion without damaging parts. Anti-Seize Compound: Helps prevent bolts from locking up in the future. Work Light or Headlamp: Proper lighting makes everything easier.
✅ Smart Installation Tips Once your tools are ready and your lift kit has arrived, it’s time to begin. Here are some essential tips that can save time, prevent mistakes, and make your installation smoother: 1. Read the Instructions (Seriously) Even if you’re a seasoned wrench-turner, read the instructions that came with your lift kit. Some kits include specific torque specs, component order, or manufacturer warnings. 2. Soak Bolts with Penetrating Oil in Advance Spray all suspension bolts—especially lower control arms, shocks, and leaf spring mounts—the night before you plan to start. This makes removal much easier and reduces your chances of snapping a bolt. 3. Work on Level Ground Safety first. A flat, stable surface prevents your truck from shifting unexpectedly when lifted. Don’t work on a slope or soft ground. 4. Lift the Entire Axle if Possible When lifting one corner of a solid-axle Kei truck, the opposite side can bind and make removal difficult. Lift both sides of the front or rear at the same time for easier suspension access. 5. Take Before & After Measurements Measure the distance from the center of the wheel to the bottom of the fender before and after the lift. This confirms the kit is functioning properly and evenly. 6. Loosen Suspension Components in the Correct Order Start by loosening sway bar links, then shocks, then the control arms or leaf spring bolts. This keeps components from binding during removal. 7. Use a Torque Wrench When Reassembling Tighten all bolts to the manufacturer’s specified torque. Guessing can lead to broken bolts, stripped threads, or parts coming loose while driving. 8. Double-Check Brake Lines and ABS Wires After lifting, make sure brake lines, ABS wires, and other connections aren’t stretched too tight. Some kits include extensions—use them if needed. 9. Get a Professional Wheel Alignment Lifting a vehicle affects camber, toe, and caster. Driving without an alignment leads to uneven tire wear and poor handling. Don’t skip this step.
⚠️ Common Mistakes to Avoid Even experienced DIYers can make these mistakes. Avoid them to save yourself time, money, and safety risks. ❌ Skipping Safety Precautions Never crawl under a truck supported only by a jack. Use jack stands rated for your vehicle’s weight and test for stability before getting underneath. ❌ Forgetting to Retorque After Driving After driving 50–100 miles post-installation, recheck all suspension bolts. Parts can settle, and bolts may loosen. Failing to retorque is a common cause of clunking or unsafe handling. ❌ Choosing the Wrong Lift Height A 2"–3" lift is usually safe. Going higher may require modifications to steering geometry, driveline angles, and brake lines—especially on older Kei trucks. ❌ Ignoring Suspension Travel Limits Installing longer shocks or stiffer springs without checking suspension travel can cause topping out or bottoming out—damaging components and ruining ride quality. ❌ Overloading the Truck Post-Lift Just because your truck is taller doesn’t mean it can carry more weight. Check the load rating of your springs and shocks before hauling extra gear or cargo.
🛞 What to Do After Installation Once the lift kit is installed, you're not quite finished yet. Here’s your post-installation checklist: ✅ Recheck all bolts and fasteners ✅ Reconnect any wiring or sensors you moved ✅ Measure height on all four corners ✅ Test drive slowly—listen for clunks or rubbing ✅ Get a professional alignment within 48 hours ✅ Retorque after 100 miles
🧭 Final Thoughts Installing a lift kit on your Kei truck is a fantastic way to boost its capability, whether you're heading off-road or just want a more aggressive stance. With the right tools, some mechanical know-how, and a careful approach, it’s a rewarding DIY project that can totally transform your truck. Just remember: safety, patience, and attention to detail are key. Take your time, avoid shortcuts, and your mini truck will be ready for bigger trails and tougher tasks in no time.
