Review on Fel Pro RDS 55387 Rear Differential by Ben Cooper

78 years. Truck of a young mother - I rely on Fel-Pro as always. Never in over 40 years have Fel-Pro products let me down, this rear differential seal fits my 1994 GMC K2500 with a 10" 14 hole rear wheel (4:10 ratio), I push my truck very hard and with the NEW 454 all 1 barrel axles, springs, ball joints and NVP 4500 gearbox with 13.5" clutch - I use all Royal Purple fluids so I insist on Fel-Pro for ALL my sealing needs - this seal is in very well protected in the packaging - Thank you Revain for a high quality product at a very good price, fast shipping and great customer service.
