This is for 2 pairs (4 springs) high quality 2.25" ID helper springs with adapters to fit 2.25" ID coil springs. Race Competition Helper Spring 3" Long, 2.25" Internal diameter, 40lb rate. Helper springs are designed to go coil bound and then return to the full free length making them suitable for retaining location of the main spring. Tender springs are used with main springs to tailor a progressive overall spring rate. The helper springs are made of flat wound material so as they compress they close completely. This flat design allows the coils to bind without creating nasty stresses, as would happen with a normal spring of circular cross-section. Will help to eliminate wheel spin.
