❓ FAQs
Q: Do brand-new RVs need shocks?
A: Yes — factory shocks are low-cost placeholders. KONI FSD makes a new coach drive like it should.
Q: Do you do mobile installs?
A: No. All work is done in our Mesa shop where we can measure, torque, and test properly.
Q: Do these upgrades help with crosswinds and passing trucks?
A: Absolutely. Stage 1 and 2 fix 80 % of those issues immediately.
Q: Will this void my warranty?
A: No — properly installed aftermarket suspension components do not void OEM warranties under the Magnuson-Moss Act.
🔧 Quick Maintenance Tips
1️⃣ Inspect shocks every 50 k miles — leaks = replace.
2️⃣ Check sway-bar bushings annually for cracks or looseness.
3️⃣ Torque wheel and suspension hardware before long trips.
Simple checks keep your RV safe and comfortable for years.
