This Pro Street subframe kit is unique and exclusive to TOTAL PERFORMANCE. Although originally designed for our Pro Street "T," the Total Pro Street subframe kit is the quick, easy, and economical way to give virtually any car or truck the Pro Street look. Designed to fit between the common 36" main frame dimension, the subframe allows the use of wide street tires. Crossmember can be trimmed for shorter inside frame rail dimensions, or we can make you a custom width crossmember for only $25.00 more. Designed with leaf springs and a wishbone-type centering control, it offers both a distinctive ride advantage and ease of installation over four-link drag race types. Note: Max inside wheel offset is 4 1/2." Kit includes complete bracketed and welded subframe, narrowed 9" Ford housing, 39 3/4" 28-splined axles, dual-leaf springs, shocks, sway bar, axle snubbers, and all the necessary mounting hardware. Allow 4 weeks for special widths. Backing plates not included.
