DLC AND MX 2-5/8" COIL-OVER SPRINGS
Integra offers both MX and DLC (Dynamic Load Control) 2-5/8" coil-over springs. MX springs are manufactured from VMX alloy steel and utilize fewer coils for
reduced weight and increased travel. DLC springs feature an aggressive barrel design for optimum performance and body clearance with maximum distance
between coils for improved travel prior to coil bind. All springs are etched with the rate and are covered by a limited lifetime guarantee.
