do i needem?where do i getem? thanks

pm member Doctor Diff.

I run them with my 489 with the thrust block in place

first set went 9 yrs,2nd set in 2yrs now and with out the inner axle seals ths go round..no leaks and have had them out a time or two

the o-ring is sealing fine

with the seals its double protection against leaks though

got my greens from the doc

he has the best deal on them

The Greens are great on a drag car, but have a small fraction of the capacity of the stock Timkens and will be short lived if you really "drive" the car. (see MP catalog for disclaimer).

I could visualize losing a wheel, but they do seem to give plenty of notice (noisy).

I'd stick with the stockers.

I don't know about being short lived if you really "drive" the car. I have over 80 1/4 mile runs and 40,000 miles on my driven car in 8 years. No issues at all.

Bought em from Doctor Diff already installed on new axles.

i got 9 yrs hard street use out of mine,80 miles a day 5 days a week

drove it like I stole it

got my 2nd set from the doc,couple yrs now,in the 440 truck now
