In a standard coil-over setup, as a spring compresses, it naturally wants to "twist." Without bearings, that twist creates friction against the spring perch, which increases the "stiction" (static friction) in your shocks. The 19502 set allows that energy to be released, ensuring your spring rate stays linear and your shocks can react to even the smallest bumps.
Detailed Technical Specifications
1. Torrington Needle-Roller Technology
-
Ultra-Low Profile: The thin "pancake" design of the Torrington bearing adds negligible height to your spring stack, meaning you don't have to worry about running out of adjustment threads on your shock body.
-
Precision Rollers: Features a cage of hardened steel needle rollers that distribute the massive vertical loads of a racing suspension evenly across the surface.
-
Smooth Rotation: Eliminates the "pop" or "creak" often heard when a bound-up spring finally overcomes friction and snaps into a new position.
2. Hardened Race Washers
-
Protective Interface: This set includes four hardened steel washers (two per bearing). These act as the "races" for the needle rollers, preventing the bearings from digging into or galling your aluminum spring perches.
-
Durability: The washers are heat-treated to withstand the high-impact environment of dirt and asphalt racing without deforming.
3. Performance Handling Benefits
-
Increased Shock Sensitivity: By removing the mechanical bind of the spring, your shocks are free to do their job. This leads to better tire contact and more "feel" for the driver.
-
Consistent Ride Height: When springs are bound up, the car can "hang" at an incorrect ride height. These bearings ensure the car settles back to its exact scale settings every time.
-
Easier Adjustments: Because the spring can spin freely, it is much easier to turn the spring seat for ride-height or corner-weight adjustments while the car is on the ground.
