Tucked behind the 4.3, the 700R4 was hard-wired to allow for a manual torque converter lockup. Behind the tranny, the 231 has a slip yoke eliminator kit to level the spring-over uprising. Wrangler springs and spring-over yield a total of 6 inches of suspension lift. Narrowed to 58 inches, both front and rear Ford 9-inch axles have 4.56 gears. Components like a front Auburn limited slip and a rear Detroit and a Currie high-pinion third member are in place for the rough stuff. Stopping happens with four-wheel discs and a Cadillac master cylinder.
