To my knowledge only PrimitiveRacing and Eibach make lift springs for our mount. I was hoping Rallitek would do it. Not so far. Off-road performance, body roll and rear sag during load/towing are improved with higher rated springs (IMO).
I don’t know much about Eibach, I hear they are good quality. One thing that made me choose Primitive was that they also included subframe spacers and more importantly STRUT spacers. This allows the beam piston to sit where it needs to initially, so it doesn’t always extend with the lifter. I’ve been told that this will destroy the strumpets quickly as it’s always closer to the end of her strike. I was trying to find my email conversation with Patrick from ADF but couldn’t find it.
Ability: the point goes to the spring lift for the reasons above. Unless your ‘ability’ is defined as the highest clearance from the ground. The lift springs offer 1.25″ and the Eibach is 1.4/1.7″. Most block lifts are 1.5″ or 2″.
The view will be similar. 2″ is more visible than my 1.25″. I run 1″ larger a/t diameter tires which gives me almost 2″ lift anyway.
I hope it helps
