Vehicle Tech Guides
Fitment and build guides for the Jeeps and trucks we work on every week. Each guide is built from factory specs, real owner builds from the forums and our own hands-on experience with these parts. Pick your vehicle below to get started.
Quick Answer
Find your make below and open your vehicle's page. Every vehicle page has a quick spec box (bolt pattern, center bore, lug thread and factory wheel and tire sizes) plus seven guides: lift kits, wheel fitment, tire size, bumpers & armor, lighting, winch & recovery and performance. If your vehicle isn't listed, or you just want someone to check a part before you order, call us at 419-670-3141.

2. What Every Guide Covers
Every vehicle page links to the same seven guides, so once you know your way around one vehicle you know them all.
| Guide | What it covers | Shop |
|---|---|---|
| Lift Kits | Leveling kits vs full lifts, how much lift each tire size usually takes, and the supporting parts (track bars, control arms, bump stops) that come with more height | Lift Kits |
| Wheel Fitment | Bolt pattern, center bore, lug thread and torque, plus the width and offset combinations owners run without rubbing | Wheels |
| Tire Size | Factory sizes by trim, the biggest tire for each lift height, load range and speedometer calibration | Tires |
| Bumpers & Armor | Winch bumpers, rock sliders and skid plates, and the sensors, cameras and fog lights that have to carry over | Bumpers |
| Lighting | LED headlights, fogs, tail lights, light bars and rock lights, wiring through a fuse and relay, and headlight aiming | Lighting |
| Winch & Recovery | Winch sizing from your vehicle's GVWR, mounting options and the recovery gear worth carrying | Winches & Recovery |
| Performance | Tuners, intakes, exhaust, brakes and gearing, split by engine so you only see what fits yours | Performance |
3. How We Build These Guides
- Factory specs first. Bolt patterns, engine ratings, factory tire sizes and weights come from manufacturer spec sheets and owner's manual data, or established spec references. If we can't confirm a number, we leave it out and tell you to check your door placard or owner's manual.
- Owner forums for real-world fitment. What actually fits on a lifted truck comes from owners' builds. We report those as what owners report, not as guarantees, because flex, wheel offset and tire brand all change the result.
- Never competitor sources. We don't copy fitment charts from other parts retailers. Each guide lists its own sources at the bottom.
4. Frequently Asked Questions
How do I find my vehicle's bolt pattern?
Open your vehicle's guide page: the bolt pattern is in the quick spec box at the top. To check it yourself on a 5-lug wheel, measure from the center of one stud to the outer edge of the stud farthest from it; that distance is the bolt circle (for example 5 in on a 5x5 pattern). On 6- and 8-lug wheels, measure center to center between two opposite studs.
Does lift height guarantee what tire size will fit?
No. Lift height is only part of it. Wheel width and offset, tire width, the actual measured diameter of the tire and how far the suspension flexes all decide whether a tire rubs. Our tire size guides show what owners commonly run at each lift height, but treat that as a starting point and call us to check your exact setup.
What's the difference between wheel offset and backspacing?
Offset is the distance in millimeters from the wheel's centerline to its mounting face. Backspacing is the distance in inches from the mounting face to the inner lip. They describe the same thing in different ways, but backspacing changes with wheel width, so an offset only means something when you know the width. As a rule of thumb, backspacing equals half the wheel width plus 0.5 in plus the offset converted to inches.
Why does my tire rub after a wheel change?
There are two kinds of rubbing. Inner rubbing happens at full steering lock, where the tire hits control arms, the frame or sway bar; less backspacing moves the tire away from those parts. Fender and liner rubbing happens when the suspension compresses; less backspacing pushes the tire farther out and can make it worse, so more lift, bump stops or trimming fix that kind.
Can you help me pick parts that fit?
Yes. Call 419-670-3141 or email sales@offroadsource.info with your year, model, trim and any lift, and we'll check fitment before you order.
