More expensive than you think.

The entire drive train is built to handle a minimum of 1,000 WHP.

RPM Level VII 4L65/70e trans (deep pan, billet 2nd gear servo, HD 2 - 3 shift valve, billet input shaft, billet pump rotor, billet forward piston, billet overrun piston, micro-polished internal components, 300m output shaft)

Billet 8620 heat treated cone for automatic flexplate assembly, SFI flex plate, RM-8035 scatter shield bellhousing, Precision Industries 3,200 stall TC, PCS TCM-2000 trans controller, B&M trans cooler

RSD line lock

DSS 1,000 WHP propshaft, DSS Urethane couplers

RPM Level IV diff with Quaife gear torque biasing LSD, 3 series rotary for diff (Z06)

DSS RA5302X5 300M Level 5 1,000 HP axles

It was not cheap! I had the good fortune to buy it already built. I have a bunch of receipts. It is impressive.

At least I don't have to worry about the drive train.
