I’m running a 9.25 behind around 450hp/600tq. I re-set endplay with a crush sleeve eliminator, added new upgraded yukon axles, and made sure it would stop well and retain the axles in case of a C-clip failure with jeep JZ disc brakes. I also went with a forged 1350 pinion yoke. I have about $700ish in it total and I have high hopes for a long life on the street with occasional 1/4 mile passes. I also went with a cast aluminum diff cover with bearing saddle supports. That part is mostly bling even though you’ll never see it under my lowered truck but discs and finned aluminum sure looks like more $ than I spent.
