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.

Tool distributors can now sell these at or near the price they've paid for previous market offings. Laser cut from 14 steel
