4" LIFT FOR 6" SYSTEMS - INCLUDES THUREN SHACKLES
Our Long Travel leaf springs are designed to give the most suspension travel possible, while still being able to hold up to extreme off-road abuse. These leafs are very soft, and give the best street ride you can get.
Details:
- Heat treated, shot peened, and manufactured from the highest quality materials available.
- Can supply true, clean, 18" of active suspension travel.
- Extended design uses shackle length and motion ratio to amplify wheel travel.
- Very soft spring rate and ride feel, more like a 1/2 ton truck.
- Designed to mount using the factory OEM u-bolts.
- High quality PTMEG Polyurethane bushings.
- Moves rear axle back slightly to help 37" tires clear the fender better.
- Almost completely eliminates axle drive chatter in soft terrain/sand.
SHACKLE NOTE: These leaf springs are extended length, MANDATING Thuren Shackles are used, and the longest length position on our shackle MUST be utilized. The factory OEM shackles will not work and leaf spring damage will occur if the shackle is not installed properly!
