## Questions & Answers

**Q: Are there counterfeit or knockoff versions of RoadActive Suspension kits?**
A: Beware of imitation kits sold online. Only genuine RoadActive Suspension products have been engineered, tested, and warrantied in North Carolina since 1998. Listings with RAS in the title are genuine RoadActive Suspension products.

**Q: How much does RAS increase payload capacity?**
A: While RAS  can strengthen the rear suspension by up to 50% in a progressive manner and can improve the way your truck handles loads; it and no other suspension upgrade can increase the manufacturer weight ratings.

**Q: Will RAS fit my lifted truck?**
A: From a fitment standpoint, RAS often fits lifted trucks without an issue.  Before ordering for your lifted truck, be sure to check your suspension for possible obstructions. If there appears to be an issue please contact RAS directly for assistance.

**Q: Will RAS help reduce my rear squat?**
A: Yes! While RAS is geared towards improving overall load handling, stability, and performance without hassle; RAS will also help reduce rear squat by up to 2-3 inches.

**Q: How is RAS different from other suspension helpers such as air bags?**
A: RAS offers a  more complete solution,  where enhancing stability, reducing rear squat, dampening excessive rebound, improving performance, and providing same-as or better-than-stock ride is just as important as reducing rear squat.
