This system uses replacement Select series front springs. Different weight-rated front springs are offered for both gas V-8 and heavier diesel and V-10 engine equipped trucks. Heavier springs are needed for the larger power plants increased weight, while the lighter-rated gas versions considerably improve the less weighty truck's ride quality. These lifts utilize new Urethane compression travel stops for the front; the factory rear stops are relocated. The system uses a dropped pitman arm for steering correction, and the track bar is lowered to keep it in phase with the drag link.
Keeping the track bar and drag link in phase is critical. Even a slight amount of bar misalignment, caused by ride height fluctuations from extra loading (winch, aux. fuel tank, etc.), can generate steering wheel "kick". Superlift offers an optional adjustable track bar if additional phase alignment is needed.
Front and rear anti-sway bar geometry is addressed by either lowering the bar body or using longer drop links. Two front and two rear Superide shocks are included with each lift suspension system. Boots are optional.
Rear lift options vary depending on the desired height and the factory suspension's configuration, but in most cases you have the option of blocks, add-a-leafs or replacement springs.

Bilstein Shock Absorber performance features:
- The shock body dissipates heat more efficiently.
- Its unique piston/valve assembly provides completely independent valving between compression and rebound cycles which allows it to react faster to changing terrain regardless of vehicle speed.
- Virtually eliminates the possibility of oil foaming with the patented "floating" piston that divides the high-pressure nitrogen gas and shock oil.
- Superior construction for strength and durability.
101-Rear u-bolts fit vehicles with and without a top-mounted overload leaf. Those without overloads will have about 2" of excess U-bolt length that can be trimmed off.
104-Rear lift based on 2.5" factory blocks. Factory block is retained with new block stacked. Vehicles equipped with a 3.5" factory block may not use the new block.
106-Part number 9641 front bumper spacer can be used on Super Duty pickups to allow for increased tire clearance.
