Heavy Duty Overdrive Spring Compressor 88-up A500, 42rh, 42re, 44rh, 44re and '91-up A518, 46rh, 46re, A618, 47rh, 47re T-1302AC is laser cut from 1/4" steel. The (3) vertical bars are welded in place using much stronger mortise-and-tenon joints; finished cleanly by machining them smooth. As a final touch we've anodized it for corrosion protection (and good looks). We've built it plenty tough enough to withstand a lifetime of usage. Over 15x stronger than it needs to be. In testing, it didn't fail until over 8 tons of pressure had been exerted on it! American made! Our high-volume materials purchasing and manufacturing power combine to keep the costs low. Tool distributors can now sell these at or near the price they've paid for previous market offings.
