For better steering geometry: Crossover Steering
ORD has assembled a line of complete lift systems for the ’73-’87 ('91) GM straight axle trucks using ORD designed parts like our Swaybar Correction/Disconnect system, Shackle Flip kit, and greasable HD shackles along with Tuff Country springs for a truly complete suspension system.
The often missed details like brakelines and steering correction are even part of the kit, literally everything you need except for installation elves is included.
Extensive testing of the 8-inch system on ORD project vehicles gives you great ride quality and handling on road along with good articulation and durability off road. 35” tires fit without modifying fenders, 37's will fit with some trimming, bigger tires will fit with more trimming, and (a 1” body lift can help too). Several spring and shock combinations are available to fit the range of GM’s from trucks to K5’s and Suburbans.
For 8" of lift we have 3 options. Typically the lower the lift height on the spring the lower the spring rate. This results in a softer ride.
At 8" of lift height and more crossover steering is highly recommended for improved bump steer characteristics and to insure lock to lock turning at all times. For 1/2 and 3/4 ton front axles, we can use a raised steering arm with a drop pitman arm and it works ok. For 1 Ton trucks, there is enough money in making the stock steering line up (~$450) that it really makes sense to go straight to crossover steering:
