Select Series
Superlift turned their engineers loose with one goal: build the best riding, most durable lift system possible for the Super Duty. Here's how they did it . . .A higher leaf count spring allows the use of thinner leaf material. The Select Series springs are 10-leaf units. Using more leafs yields a progressive leaf stack, which produces a much smoother spring rate curve throughout the suspension cycle. The even, linear compression rate curve of the Select springs is the primary key to good ride quality. Additionally, as overall spring pack thickness increases, the amount of arch that is needed to attain a given lift height decreases. Reduced arch translates into less inter-leaf friction and less shackle movement, all of which improves ride quality.  And, it is not a "one spring rate for all" mentality; there are different designs for trucks equipped with a V-8 gas engine or the heavier diesel and V-10. Other design features include anti-friction pads inserted between the leafs for a smoother ride and quiet operation, full military-wrapped spring eyes for superior durability and functional urethane compression travel stops.

Features:
Track bar relocation bracket 
Dropped pitman arm - 6", 8", 10" only (not needed for 4" lift)
Replacement front anti-sway bar links
Drop brackets for front compression travel stops
Superlift or Bilstein shocks with yellow boots

All 2" leaf spring lifts for Super Duty trucks are the  Superide tapered leaf springs, not the Select Series.

Kits use rear blocks and/or add-a-leafs. Systems use rear leaf springs.

Upgrade kit to convert 8" lift into 10" lift.
Front kit includes 2" lift spring hanger/shackle system; front brake hoses; adjustable track bar 
Rear kit includes 3" lift block kit & u-bolts; rear shock bracket; heavy duty rear compression travel control and load assist system.

Super Duty 10" Lift System Features:  In an effort to keep spring arch to a minimum - remember that reduced arch improves ride quality - we use our superb riding 8" lift Select Series front springs with our 2" lift spring hanger / shackle system.  7" replacement rear springs and 2" lift blocks raise the rear. The same areas that we address in our 8" system (steering and track bar geometry, shock length, etc.) are addressed in the 10" lift system, and then some.  The 10" system also includes longer Bulletproof front brake hoses, our adjustable track-bar for precise bar "phasing", and rear dual shock brackets (the extra pair of rear shocks are ordered separately).  The 10" lift includes 4 shocks. An optional dual front shock system is available.    

Another noteworthy component of the 10" system is Superlift's new heavy-duty rear compression travel control and load assist system.  Offered only by Superlift, the system utilizes specially designed hollow rubber cushions that greatly improve rear suspension ride quality and load control.  Having effective compression travel control allows the use of Superide replacement rear leaf springs that offer a great ride, due primarily to their relatively light spring rate.  The cushions assist only when operating conditions call for extra spring rate - such as bad roads, hauling or towing.

If you have a Super Duty and either work hard or play hard -- if you want a little lift or a lot -- Skyjacker has designed a smooth performance system with your needs in mind. The 4" & 6" lifts include Softride springs, rear blocks or leaf springs, front sway bar links& massive track bar drop brackets. A pitman arm is required & sold separately. 

The 8" standard lift include all of the above plus a power steering pitman arm, both front and rear sway bar links, front & rear stainless steel braided brake lines and a carrier bearing lowering kit.

The Softride springs manufactured by Skyjacker use tapered leaves to yield a lower spring rate and better travel, Teflon wear pads to help reduce interleaf friction, a "bolt" style clip to reduce leaf friction and shotpeening to compress the steel and increase its tensile strength. 

99-04 Adjustable track bar w/ 4-8" lift 

Skyjacker lift kits available in black only.

Kits use rear blocks. Systems use rear leaf springs.

Skyjacker also offers a 6" & 8" Z-Link Coilover conversion for the Super Duty. This system allows you to remove the factory equipped front leaf springs and convert to a coil-over front suspension. This allows for greater suspension travel and improved ride quality. This is an easy, bolt-o0n installation only requiring you to drill 4 holes per side to convert to the ultimate setup.

Features:

• Bolt-on Coil-Over Conversion

• Greater Wheel Travel

• Multi-valved Coil-Over front shock

• Massive 2" piston bore

• Huge 22mm piston shaft

• Off-road Race inspired adjustable wafer valving

• Heavy-gauged 3.175mm steel body wall]

• Preset Softride front coils

• 6" clears 36's. 8" clears 38's
