B12 (Special) - Coil Spring Set (36-281824)

Bilstein is the only rear lift spring option on the market that is closest to oem spring rate. These gave me around a 2 lift in the rear with full tank and one ome spacer (.4) on the drivers rear to compensate for lean. I have these matched up with kings coilovers in front and shocks in rear with compression adjusters. I previously had wheelers t13s that only gave a little over 1 of lift after they settled. If your at stock weight or with sliders these are an excellent choice to match a 2-3 front lift depending if you want level or factory rake.

I've got 5100s all around, set 1.75 up front. Wanted a slight forward rake so I took out the stock springs with 1 Cornfed spacer I had in there, and installed these. It lifted the booty a little more, exactly like I was hoping.

Ideally, springs only keep the vehicle at the desired height. Anything else is best handled by the shocks and the sway bars. These springs are made to work with Bilstein 8100 rear shocks and they make for the best combo available on the market: one full step above Fox and King offerings as the 8100 are external bypass shocks with a 2.65 body. Only Icon offers a comparable rear shock. BP51 is a much smaller piston as is the Fox TRD Pro shock: excellent for most uses but not top of the foodchain.So, with an 8100, these springs are perfect for they keep the factory spring rate and you can stiffen as needed from the shocks. The springs can also be used with well-tuned Fox or King or Icon shocks or with adjustable shocks from these brands. Even so, these springs are best used for vehicles that move faster or go in bigger rocks rather than for OZ-style expedition vehicles that always carry lots of weight. Such rigs would benefit from simpler setups with cheaper shocks and heavier duty springs.Light-duty applications on a lightly loaded vehicle would benefit from these springs with 5100s in order to keep comfort as good as it can be on a cheap shock but can also consider the Eibach 1 spring or the 1.5 Wheelers/Eibach T13 if they carry rear seat pax and/or more weight in the back.In sum, know your needs. This is a fantastic spring and the only one at this low spring rate. So the question is to choose the correct spring (and it is more important to choose the correct shock, springs are easy to replace anyway). For a stock-like rate lifted spring, this one is the only game in town.
