Wehrs Machine WM404RC 5 Inch Bolt-In Raised Spring Cup with OD Alignment

The Wehrs Machine WM404RC is a bolt-in raised spring cup designed for 5-inch diameter coil springs used in dirt late model and modified race car suspension systems. This raised cup moves the spring table up 1 inch from the standard WM404SC cup, providing additional clearance for shock mounting and trailing arm configurations.

Key Features:

• OD grab design centers the spring on the outside diameter to keep the spring in line better than a standard cup
• Bolt-in installation for easy removal and maintenance
• Raised design provides 1 inch of additional spring height
• Precision-machined steel construction for durability
• Works well with WM165BO 5-inch Torrington bearing to help reduce spring twist friction

The outer diameter alignment system ensures proper spring tracking throughout suspension travel, reducing binding and improving consistency. The bearing is only recommended if you stay in tension through travel. This spring cup is ideal for racers looking to optimize rear suspension geometry and improve shock clearance on dirt track applications.
