Our 6 leaf progressive add a pack rear springs are a proprietary design built for us by Deaver Spring MFG. The lower overload leaf is removed and is replaced with 6 thinner gauge leaves. The O.E.M. load capacity is maintained while improved ride is achieved.
These packs are designed to eliminate the incredibly harsh rebound of the factory overload spring they replace helping to tame the medium to large bumps when paired with a Carli Suspension System.
