Peterbilt non-LCF 386 Springs (2005-6)

4" Width Springs (Not for Low Cab Forward)

386 First Design

2005-6

First design (OEM numbers beginning with "HK") springs were generally only used until 2006.  For increased durability, conversion to threaded bushings and pins is an option; in place of RB-295 bushing use TB-77 with 327-540 pin.
