Bilstein's 6112 shocks are the go-fast go-big upgrade over the 5100 series. With a much thicker body and 60mm piston, the damping ability of the 6112 exceeds normal 2 inch shocks. More damping surface from the 60mm piston provides more consistency in similar terrains vs the 5100, Less work required with the 2.6" 6112 results in less harshness and more comfort. Another big advantage of the 6112 shock are the various height choices to account for different weight loads or tire clearance requirements. With Bilstein's build quality and reliability, these shocks do not need to be serviced as soon as similar 2.5" shock offerings.
This kit uses the 6112 front shocks and springs as the baseline, with interchangeable rear shocks according to lengths required. Rear lift options at 2" or greater will require an extended length rear shock to accommodate.
Bilstein Front 6112 - 47-294301
Bilstein Rear 5100 - 24-294225
Bilstein Rear 5160 - 25-294316
- Uses new included coil springs for the 6112 shocks, lift height is achieved through the numerous circlip rings on the shock; adjusted prior to install.
- 60mm piston means more damping surface volume, and having to do less work than a smaller (2in) shock or 46mm piston, one word - consistent.
- For more aggressive offroad use compared to the 5100 series
Upper Control Arm Options
All available arms allow for more suspension articulation compared to stock arms on a lifted vehicle, and easier alignment, which is important when lifting the vehicle 3-3.5".

Rear Lift Options
There are many options to lift the rear of your Ranger, with their own pros and cons. Traditionally we recommend a progressive add-a-leaf setup that both improves handling and height requirements with additional weight, without negatively affecting ride quality too much. Old Man Emu leaf packs come with the required Greasable Shackle Kit (OMEGS20), Greasable Pin Kit (OMEGP10), Rear spring Bushing Kit (OMESB117), Rear Spring Bushing Kit (SB118), Leaf Spring Ubolts (OMEU81/82/83).

Rear Shock Options
Bilstein 5100 are great for an all around upgrade over factory shocks, and can handle moderate offroad terrain on top of improved road handling manners. The 5160 series are for heavier offroad use where maximizing shock travel and shock fade are a concern.

Bilstein 6112/5160 Combo
Been great working with Shock Surplus! Fast, friendly service! Product arrived as described and on time!
Good service, poor quality control
Parts arrived quickly and tracking numbers were sent right away. FedEx delivered half of my purchase and did not require a signature. UPS delivered the second half and did require a signature. Small detail but was a concern for me at my apartment complex. My major complaint was that I paid Shock Surplus to assemble my struts/coils and I discovered that they sent me two driver side assemblies. I discovered this only after I tried to install several times. I had to rent my own coil compressor which was dangerous and I was hoping to avoid. The whole reason I paid for assembly was to avoid using a small shock compressor on a large shock. My truck ended up sitting on jack stands for way longer than anticipated and I was left without a way to drive for several days due to this small mistake. Parts arrived quickly, but I wish they would have taken more time to assemble them correctly to begin with.
