2005-2011 Ford F250/F350 Super Duty Progressive Rate Coil Springs!
Top Gun Customz is proud to offer our line of progressive rate coil springs for the Ford F250/F350 Super Duty 4x4's!! We have these available in the following lift heights...2.5", 4.0 and 6.0". The ride and performance of these is incredible. Combined with a quality shock, you will not find a better ride in a coil sprung Super Duty. Nobody else is offering the variety of heights in a progressive rate coil.
Unlike stock coil springs, these springs have multiple, or progressive, rates. The initial rate of these coils (driving around town) is softer than stock. As the spring compresses more, the rate increases (heavy cornering, off road, etc. With progressive rate coils the first few coil wraps are more closely spaced than the remaining coils. These springs are really the best of both worlds....super soft on the street, and a higher level of performance and control off road.
These are shot peened and pre set. They are powdercoated black for a long lasting finish. We recommend pairing these with a quality shock to take the most advantage of these incredible coils.
