Returns & Warranty
What is your return policy?
Returns must be requested within 30 days of delivery. Items must be unused, uninstalled, in original condition, and in the original packaging. All returns require approval before being sent back, so contact us for a Return Authorization (RA) before shipping anything. Customers are responsible for return shipping unless the return is due to our error or a confirmed defective product. Original shipping charges are non-refundable, and approved refunds are issued to the original payment method within 5 to 7 business days after inspection.
What if I receive the wrong part?
If your order arrives incorrect, contact us within 48 hours of delivery at info@treklinemotorsports.com with your order number and photos of the item and packaging. We'll review the issue and assist with the next steps. Return shipping is not the customer's responsibility when the return is due to an error on our part.
What if my part arrives damaged?
Contact us within 48 hours of delivery at info@treklinemotorsports.com with photos of the damaged item and packaging, plus your order number. Keep all original packaging until the claim is resolved so we can assist with the carrier or product issue promptly.
Do your products come with a warranty?
Trekline Motorsports provides a limited lifetime warranty to the original vehicle owner against defects in materials and workmanship. Our obligation is limited to repair or replacement of the defective product. Removal, installation, freight costs, and incidental or consequential damages are not covered. Normal wear items, cosmetic finishes, improper installation, and failure to follow installation instructions are not covered. For a full rundown of how aftermarket parts interact with your factory vehicle warranty, see our does a lift kit void your warranty? guide.
Fitment & Compatibility
How do I know if a part fits my truck?
Every product listing includes the specific year range, make, model, and drive type (2WD or 4WD) it fits. Check that your truck matches all of those specifications before ordering. If you're not sure, email us at info@treklinemotorsports.com with your year, make, model, cab style, and drive type and we'll confirm fitment for you.
What's the difference between 2WD and 4WD parts?
2WD and 4WD trucks often use different front suspension and drivetrain layouts, so many parts are not interchangeable. Many 2WD/RWD trucks can use spindle-based lift or drop parts because the front wheels are not driven. Many 4WD IFS trucks must also account for a front differential, CV axles, steering geometry, and alignment range. Always order by year, make, model, drivetrain, suspension type, and product notes. For a deeper dive, read our 2WD vs. 4WD lift kit guide.
I have a 2WD truck — can I still lift it?
Absolutely. We carry a full range of lift options for 2WD trucks including lift spindles, strut spacers, lift blocks, and lift shackles. In fact, 2WD trucks are generally easier and cheaper to lift because there's no front differential or CV axles to worry about. Lift spindles are one of the most popular 2WD lift methods because they raise the truck without changing suspension travel.
Do I need to specify my rotor thickness when ordering spindles?
Yes — this is one of the most common fitment mistakes. Many GM trucks came with either 1-inch or 1.25-inch thick rotors, and the spindles are different for each. Check your rotor thickness before ordering. If you're not sure, measure the rotor at its thickest point (the hat area doesn't count) or email us with your VIN and we can help you verify.
Will your lift kit work with my existing wheels and tires?
It depends on the truck, kit, wheel width, offset/backspacing, tire size, brake clearance, and trimming. Many stock wheel and tire setups still fit after a lift or leveling kit, but you should check the product listing and contact us if you need help confirming clearance before ordering.
Lift Kits & Leveling Kits
What's the difference between a lift kit and a leveling kit?
A leveling kit usually raises the front of the truck 1 to 3 inches to reduce the factory nose-down rake. A lift kit raises the truck overall and usually includes front and rear components. Lift kits can improve frame/body clearance and make room for larger tires, while axle or differential clearance usually increases from larger tire diameter. For a detailed comparison, read Lift Kit vs. Leveling Kit: What's the Difference?
How much does it cost to lift a truck?
It depends on the type of kit and how high you want to go. A basic leveling kit starts at $35 for parts. A 3- to 4-inch suspension lift runs $250 to $650 for parts. A full 6-inch kit can cost $800 to $2,000+ for parts alone. Add $100 to $1,500 for professional installation depending on complexity. We break down every cost in our guide: How Much Does It Cost to Lift a Truck?
Do I need an alignment after installing a lift or leveling kit?
Yes. Any change to ride height can change alignment, so a professional alignment is strongly recommended after installation. Skipping the alignment can cause uneven tire wear, pulling, or poor steering feel. Budget roughly $100 to $200 for a four-wheel alignment depending on your area and vehicle.
Will a lift or leveling kit void my truck's warranty?
Not automatically. A lift or leveling kit does not erase an entire warranty, but a related claim can be denied if the modification, installation, wheel/tire setup, or related change caused or contributed to the failure. Trekline can help with fitment and product questions, but we cannot approve, deny, or guarantee any vehicle warranty claim. Keep receipts, installation records, and alignment paperwork. Read our full breakdown: Does a Lift Kit Void Your Warranty?
Can I install a lift kit myself?
Some smaller bolt-on kits can be installed by experienced DIYers with the correct tools. Torsion bar systems are under load and require the proper unloading tool. Spindle lifts and mid-range suspension kits require more skill because steering, brakes, ball joints, and alignment are involved. Larger lifts should be installed by an experienced shop.
What tools do I need to install a lift kit?
At minimum, you'll need a floor jack, jack stands, a socket set (metric and standard), a torque wrench, and penetrating oil. Some kits also require a spring compressor, ball joint separator, or brake line wrenches. The specific tools depend on the kit — check the product listing or included instructions for the full list. If your build involves leaf springs, our U-bolt torque specs guide is worth saving.
Do I need new upper control arms after a lift?
It depends on the truck, lift height, and alignment results. On many independent-front-suspension trucks, aftermarket upper control arms are recommended around 2.5 to 3 inches of front lift because they can improve ball joint angle, caster/camber range, and tire clearance. Mild leveling kits may work with stock arms if the truck aligns correctly. For specifics, see Upper Control Arms After a Lift.
Lowering Kits
How do I lower my truck?
There are several methods depending on how much drop you want. Drop shackles lower the rear 1 to 2 inches. Drop coils lower the front 1 to 3 inches. Drop spindles lower the front 2 to 3 inches without losing suspension travel. Flip kits lower the rear 5 to 6 inches. Most builds combine a front and rear method — like 3-inch drop spindles with a 5-inch flip kit. See our full guide: Complete Truck Lowering Guide, and our step-by-step drop spindle installation walk-through.
Do I need a C-notch to lower my truck?
It depends on the rear drop amount and the truck. Deep rear drops and flip-kit setups often require or strongly benefit from a C-notch to create clearance between the frame rail and rear axle. Always check actual frame-to-axle clearance, bump stop position, and suspension travel before driving.
Will lowering my truck make the ride harsh?
It depends on the method and how low the truck goes. Drop spindles usually preserve ride quality well because they do not shorten the spring. Drop coils, aggressive drops, poor shock choice, or limited bump stop clearance can make the ride firmer. Matched shocks and proper clearance checks make a big difference.
