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.
