Solid lifters are usually required for certain camshaft profiles and extremely high reving or boosted engines. (8200 rpm + and 2bar +)
In such engines the original lifter can go soft and therefore prevent consistant contact between the cam follower and cam lobe. If this occured the engine would not benefit fully from the cams profile and in worse cases can cause the follower to dislodge.
Pictured above are both items, the solid lifters are Black and the lash caps Silver.
