I’ve installed several of these Mopar Viper 4:10 gear sets p\n P5007043 manufactured by Dana Spicer
http://www.moparonlineperformance.co...p/p5007043.htm
They are best 4:10 gear set available for the ZR-1. A number of members here are running them.

Phil and Wazoo put my Viper 4.10 gears in April 2015. Photos from that maintenance day, always a blast! No issues with the gears.

Have one of Phil’s 4.10 diffs. Expertly done. My set up is a bit different since I’m running 345/19’s in back, but it turns out so is Phil.

Same here. I bought a used diff and Phil rebuilt it for me with the 4.10 Viper gears, rebuild kit and new clutch plates. Also an opportunity to install C-Beam plates. Nice and quiet. Perfect upgrade for my mostly stock car.

Very true...People are hung up on numbers..A lot dont realize how much weight plays a factor..

Watch some roll races of 3,200 lb vettes versus chargers and mustang....Vette giving up 1-2 hundred HP and still pulling away...Aero also is a huge factor as well..
