This set of gears and cogs was top notch. I .

This set of cogs and cogs was top notch. I had to retune my Silverado after picking it up and putting the 35s on it. This parking lot was just what I needed, but don't forget to buy a gasket kit.

Pros
  • Special Offer
Cons
  • Compatibility

The tuning was very different from the old gears

appearance was good quality but it took about 10 tries to fix backlash and contact area. Compared to other gearboxes I have installed, this set took significantly longer.

Pros
  • delivery was very fast
Cons
  • update available

Great replacement for 1990 Chrysler 9 1/4 Dodge RC

Perfect match for my 1990 Dodge Ramcharger with Chrysler 9 1/4. No positive difference in noise because my old one has been very worn since I've had it...the gear wasn't preloaded and the crush washer dug a hole in the gear. I have used this on an Eaton TruTrac LSD but it would fit on an OEM piece.

Pros
  • . Simply amazing!
Cons
  • Not bad, but...

does not fit gearbox and transmission

does not fit my 06 econoline. The screw pattern on the ring gear was smaller than the pattern on the carrier. I'm not sure if I received wrong parts or differences in holders. 8.8. The retainer is a Yukon Duragrip that has been tested to fit the factory sprocket. Someone returned this box with an 8.8irs 4:10 gear set for a Ford Mustang. Amazon took care of it and a replacement is on the way.

Pros
  • GOLS certified
Cons
  • Only available in black
