Trucks and SUVs with independent front suspension (IFS) need limit straps whenever they're lifted. Full suspension droop on an IFS truck overextends CV axles, tears brake lines, and damages upper control arms. A $50–$150 set of limit straps prevents $400–$1,000+ in drivetrain damage. Every vehicle below has different geometry — pick your truck and get the right spec.
