The springs in the primary basket dampen load changes between the crankshaft drive, clutch and gearbox. Softer spring settings are usually sufficient for close-to-production engines. With heavily tuned smallframe engines from around 30 hp, however, significantly higher forces act on the primary drive. Here, hard primary springs can help to make the suspension in the basket more resilient and allow the drive to work in a more controlled manner under high loads.
The spring kit is intended for engines where a standard primary basket no longer matches the load. Typical areas of application are high-torque cylinders, high resonance exhaust systems, sporty transmission setups and setups that are regularly subjected to high loads in everyday use or on the road. The springs do not replace a test of the entire primary drive: basket, repkit, pads, clutch, sprocket and bearings must match the performance level.
Only consider primary basket, repkit, rivets, screws or other mounting accessories to be included if they are listed separately in the specific item scope of delivery.

The hard EGIG PERFORMANCE primary springs are designed for Smallframe and Ape 50 engines with a significantly higher power level. For setups from around 30 hp, they ensure a firmer tuning of the primary basket and are therefore suitable for engines in which torque, load changes and load in the drive are significantly above the standard level.
