You can find some details at www.jericoperformance.com

The DR4-4 is an upgrade over the DR4 with bigger components for more strength and about $1200 cost increase. Beyond that, with the DR4 you can upgrade to a billet front bearing retainer, the 6.5 lb heavier HD aluminum case, roller tailshaft bearing instead of bushing. You can pick drag race sliders, or to allow downshifting, the road race sliders. You can get early Muncie length, or 3" longer than that (shorter driveshaft = higher critical speed).
