Skyjacker 172DR 2in Dual Rate Coil Springs for 66-79 Ford F100/F150/Bronco 4WD

Vehicle Fitment

• 1966-1976 Ford F-100, 4WD
• 1976-1979 Ford F-150, 4WD
• 1978-1979 Ford Bronco, 4WD

Fitment Notes

• Front coil springs only, sold as a pair
• Straight bolt-on, direct-fit installation - simple remove and replace of the factory front coils
• Distinct from Skyjacker's standard single-rate "172" Softride spring - this is the Dual Rate (DR) long-travel version, engineered specifically for increased articulation
• 2-inch lift height

Features

• 2-stage dual rate long-travel design, with spring rate progressing from a first "Flex Rate" to a second "Ride Rate" as the suspension compresses
• Maintains the coil seated in the spring bucket even at full droop, maximizing articulation while keeping tires in contact with the terrain over uneven trail surfaces
• Delivers a comfortable ride along with the flex needed for increased articulation - allowing full articulation as the suspension cycles
• Engineered to maintain proper OEM suspension geometry, avoiding the alignment and handling issues that can come with poorly matched aftermarket springs
• Precision-engineered progressive variable rate provides vigorous off-road handling without sacrificing smooth street ride characteristics

Product Description

The Skyjacker 172DR is a 2-inch front coil spring pair engineered specifically for 1966-1976 Ford F-100, 1976-1979 Ford F-150, and 1978-1979 Ford Bronco 4WD trucks running off-road. Rather than a standard single-rate spring, Skyjacker built this as a true 2-stage dual rate long-travel coil, with spring rate progressing from an initial Flex Rate through to a firmer Ride Rate as suspension travel increases.

That dual-rate design serves a specific purpose: the coil stays properly seated in its bucket even at full droop, maximizing suspension articulation and helping keep tires planted on the terrain across uneven trail obstacles. At the same time, the progressive rate delivers a genuinely comfortable ride on pavement rather than the harsh, bouncy feel that can come with a purely off-road-tuned spring.

Engineered to maintain proper OEM suspension geometry, this spring installs as a straightforward bolt-on, direct-fit replacement for the factory front coils - no additional geometry correction parts required for the base 2-inch lift application. This is the front coil spring pair only.
