    Tru-Coil front coil springs are simply the finest on the market. These front coil springs are designed exclusively for oval track racing, and are guaranteed to withstand the rigorous conditions of the track. What makes these springs so durable is that they're constructed from chrome vanadium steel. Chrome vanadium steel is a premium material that has unbeatable strength and toughness, plus is fatigue resistant to scorching hot temperatures. Tru-Coil front coil springs are guaranteed to stay "Tru" to their rate and shape.

    Along with a chrome vanadium steel construction, these front coil springs have a powder coated finish. Powder coating is tougher than paint, resulting in a more durable product with superior corrosion protection. With their highly visible, remarkable purple color, these coil springs are easy to spot in victory lane. They can be used with shims or weight jacks and come in various rates ranging from 475 to 1450. Varying rates allows a racer a greater range in their chassis setup. Spring rates are marked on the coil spring for easy identification. Tru-Coil front coil springs are ground flat on one end. 

    These amazing front coil springs will fit 1973 and up Chevelles and Monte Carlos, 1970 and up Camaros and Firebirds, and 1975 and up Novas and most fords. To top it all off, Tru-Coil front coil springs are affordably priced and are sure to meet the racer's budget. Such low prices make it extremely easy to experiment with different spring rates, allowing the racer to find the perfect one. Tru-Coil front coil springs are simply the best bang for the racer's buck!
