DANA 36 vs DANA 44


yes LOOK THRU THE POSTED LINKS

The C-4 Dana 36 was the only axle available in 1984 Corvettes. In 1985, Chevrolet brought out the Dana 44 which was similar to the 80-82 Corvette axle, but not interchangeable. The Dana 44 axle is considerably stronger, but not indestructible. The Dana 36 and the Dana 44 (44's in some autos and all manuals) axles were used through 1996.

The Dana 44 is much larger than the D36. The 44 has a larger, "beefier" carrier/components to handle larger (lower) ring and pinions, and increased torque. NOTICE THE LOCATION OF THE TOP CENTER BOLT HOLE ON THE DANA 36 THATS NOT ON THE DANA 44 REAR, thats a QUICK WAY TO TELL THEM APART

I ran and still (at least temporarily)run a DANA 36 in my 1985 vette with a 383 that makes about 475 flywheel hp BEFORE I hit the nitrous....if I don,t use slicks and only street tires the traction (or lack of it) acts like a fuze that tends to prevent the full torque loads from impacting the rear suspension, but I don,t do hard launches either, I baby the car off the line and play catch-up in the mid and far track, the few times Ive run slicks Ive twisted off u-joints and half shafts rather quickly and Im sure the rear is marginal,but the dana 36 has held up so far, but even the dana 44 is MARGINAL (but obviously better) in my opinion.
In my big block 1968 vette I destroyed the stock rear the first time I used slicks, I installed a custom fitted dana 60 live axle and tubbed the rear, adding a 4 link suspension on that car, it cost me a small fortune but with a 13.7:1 cpr 496 BBC I didn,t really have a choice.
Im on a pension so moneys darn tight but evenually Ill install a similar engine and a 4L80E trans in my 1985 vette and a similar rear suspension
