CR811 High Response Spring; Long Black - 2.6 lb/in (pr)

The Core RC SCH-CR811 High Response long black springs (2.6 lb/in) are designed for off-road buggies running big bore shocks. Developed with Schumacher engineers and top drivers across low-grip dirt to high-grip carpet, they sharpen suspension response compared with alternative CORE RC and Schumacher Big Bore springs. Supplied as a pair (2).

Featuring fewer coils and a thinner wire diameter, these long rear springs reduce weight by around 4 g per pair versus previous Core RC springs, helping the suspension react faster, maintain traction and improve consistency.
