FAQs About Lift Kits, Tires, and Modifications | SWAT Customs
Thinking about lifting your Jeep, truck, or SUV? Upgrading your wheels and tires? Below, we briefly answer the most common questions we get at SWAT Customs, your 4x4 modification experts in Fremont & Galt, CA.
- Will my lift, wheels, and tires affect fuel economy?
Yes! Any modification—especially larger tires, wheels, and a lift kit—can reduce MPG. The exact impact varies, but expect at least some loss in fuel efficiency.
- Will a lift kit or other mods void my warranty?
Probably not! Legally, a dealer must prove that your modification caused the failure in question. That said, replaced parts won’t be covered, and some dealers may push back more than others. In California, the Bureau of Automotive Repair can help if you face warranty disputes.
- Can I fit X tire with Y lift without trimming?
Maybe! Online forums and social media often lack context—a setup that works for one build may not work for another. We have the experience to determine what actually fits without rubbing or cutting.
- Why do people say spacer lift kits are bad?
Spacer kits are a cheap way to lift a vehicle without improving performance. Downsides include:
❌ Increased wear on suspension & steering components
❌ No ride quality or handling improvements (may make both worse)
❌ No adjustability or increased load capacity
❌ Potential safety concerns for off-road use
We recommend performance-oriented, complete lift kits designed for ride quality, durability, and off-road capability. We try to avoid incomplete kits that do not include control arms, track bars, or other required components.
- I found parts online for cheap! Can you install them?
Yes, but there’s a catch. When you buy online, YOU are the warranty. Many online retailers offer minimal support if a part is defective. We install customer-supplied parts (from major brands) but cannot warranty parts we don’t sell. Plus, local shops may price-match, saving you hassle. If you really want to save money and hassle in the long run, work with your local experts!
- Do I need an alignment after lifting my truck or Jeep?
Yes! A suspension lift alters steering geometry, so an alignment is necessary to prevent uneven tire wear and poor handling. We include an alignment with our professional lift kit installations.
- Will my truck ride rough after a lift?
Hopefully not, but it depends! Cheaper spacer lifts can stiffen the ride, while quality suspension kits like those from Bilstein, Fox, Dobinsons, Eibach, and others are designed for comfort and control. These kits may require extra consulting to setup correctly, and we will take the time to work with you on this and make sure you know what to expect.
- What is death wobble and how to I stop it?
If your solid front axle Jeep or truck shakes violently at high speeds, worn steering or suspension components may be to blame. Common culprits include the track bar, ball joints, drag link, and tie rod ends. We can diagnose and fix death wobble by replacing the faulty parts, or head it off at the pass with heavy-duty steering upgrades.
