There are few things more frustrating that having to chase exhaust leaks. And Ma’ Mopar’s insistence on equipping head studs in all of its iron cylinder heads doesn’t help when many run into water – often resulting in rotted, corroded or brittle studs that break off. Too often home-garage builds defer to whatever hardware they’ve got laying around in a coffee can, and that isn’t much better either. That’s why Proform Parts has come up with a better solution:
Proform’s wedge-locking header and collector bolts offer the final solution to headers rattling loose or collector gaskets wriggling out. Their Wedge Locking Header Bolts grip harder than regular run-of-the-mill bolts and lock-washers, or even those fancy header bolts with knurled shoulders that somehow keep requiring you to re-tighten them mid-season.
No more rusty studs. No more snapped bolts. No more re-torquing. No more gasket blow-outs.
Instead, these 3/8” dia x 1” hex headed bolts come with (4) knurled-sided, wedge locking washers that not only grip but mechanically interlock securing torque specs as they’re set.
Available nickel-plated or in black oxide, each bolt is made out of Grade 8 (12.9) steel and sold in either 16-piece, 12-piece or 6-piece kits – providing you full coverage for your particular engine build. As Proform says, “Set it. Forget it. Focus on racing, not re-torquing.” You can get yours now only at Proform HERE.
