FAQ
1. How do I confirm a part fits my vehicle before ordering?
Match the product's fitment notes against your exact year, make, model, drivetrain, trim and suspension setup, not just the vehicle name. Kits with the same advertised lift height or the same bolt pattern can use different components, and many listings exclude specific trims or factory systems such as air-ride, MagneRide, ARC, Raptor, TRX, Rebel, Trail Boss or AT4. Review the exclusions on the exact listing you are considering before you order.
2. Why can the lift height or spacer thickness differ from the number in the title?
Suspension geometry can make the resulting lift greater than the physical spacer thickness; one listed kit uses a 3/4-inch spacer to produce an advertised 1.5-inch front lift. Rear blocks work the other way: if a new block replaces an existing factory block, the added height is only the difference between them. Use the product's stated lift height and application notes rather than choosing by thickness alone.
3. Do I need an alignment or professional installation after changing ride height?
Plan to have the alignment checked after any ride-height change, and follow the installation instructions for your specific kit. Several listings recommend professional installation, and the final check should cover suspension, steering, wheel and tire clearance through full steering and suspension travel before normal use.
4. How do I choose wheel spacers or adapters, and which specifications must match?
Confirm bolt pattern, hub bore, stud thread size (diameter and pitch) and thickness; a matching bolt pattern alone does not establish fitment. Note that 6x5.5 and 6x139.7 are the same six-lug pattern, and 5x4.5 and 5x114.3 are the same five-lug pattern. Each spacer moves its wheel outward by its thickness, so check fender, liner, brake and suspension clearance and confirm stud length or included hardware before driving. Spacers keep the same bolt pattern, while adapters change the wheel-side pattern, so an adapter conversion needs both sides verified.
5. How do I choose the right lug nuts, and how many do I need?
Match the stud thread size and the seat shape your wheels require; two nuts can share a thread size but use different seats, lengths or shanks, so thread size alone is not enough. Count the studs on every wheel you plan to service: four five-, six- and eight-lug wheels require 20, 24 and 32 nuts. Check pack size and whether a key is included, use hand tools where the listing advises against impact wrenches, and verify final torque with a torque wrench.
6. What is included with the product, and are instructions supplied?
Package contents vary by listing. Some kits include hardware, bushings, keys or adapters and others do not, and pack quantities differ between similar-looking products. Review the included-parts list for the exact item you are ordering, and confirm whether instructions, adapters or additional components are needed for your installation.
7. Will these parts add power, improve fuel economy or increase towing capacity?
No universal gain can be promised. Results depend on the application, the selected component and the condition of the rest of the system, and a stated result for one vehicle is not a guarantee for another. A hitch or carrier does not raise your equipment's rated towing capacity. Fitment also does not establish emissions compliance or road legality, so check the requirements that apply to your vehicle and the specific product before purchase or installation.
8. Can you help me check fitment before I order?
Email support@dynofitauto.com with the product link and your vehicle's year, make, model, engine, drivetrain and trim, plus any modifications such as a lift, engine swap or aftermarket wheels. Photos of the mounting area or the original component help us answer faster. A fitment confirmation covers compatibility only and is separate from any road-use or emissions approval.
