You have found the strongest Differential to Subframe bolts on the market, this is not a cheesy through bolt with nuts and lockwashers from a hardware store! These bolts meet the strict ISO 898-1 specification and testing requirements and have a Tensile Strength of over 150,000psi!
This Bolt kit from MMR replaces the Factory 1 time use (torque to yield) bolts. This kit has addressed the mis-alignment issue by including Chromoly Sleeves to take up the massive amount of slop in the factory rear bushings. This translates into proper rear differential to subframe alignment which helps reduce vibration from mis-aligned or loose fitting differntial housing bolts.
The Bolts exceed OE quality and strength.
Unlike other brands, the MMR bolt kit does NOT require the subframe to be lowered or the fuel tank to be dropped, they are a direct bolt in!!
