Fifty Years of Innovation
Total Cost Involved Engineering (TCI), celebrating its 50th anniver- sary in 2024, also recently launched its new K5 Blazer/Jimmy “Pro1” chassis that’s as capable off- road as on-road. TCI’s new ‘69-72 4x4 K5 Blazer Pro1 4-link chassis is built to be a direct replacement for
K5 Blazer or Jimmy chassis with the potential to use up to 37” tall tires with full turning radius, travel and articulation. The chassis design is built around late-model LS/LT engine/trans platforms using a driver-side output Atlas Transfer Case. All frame rails are
10-gauge plate steel and to ensure torsional rigidity, a unique triple-wall frame rail design places a third vertical wall down the middle of the frame rails. The chassis features a widened front half of the frame to provide additional steering and header clearance. All cab, floor, core support, engine, trans- mission, transfer case and bumper mounts are included. Maximized-length link bars provide minimal wheelbase change throughout travel and have the added benefit of limiting roll steer. The coilover angle is close to vertical to keep the motion ratio close to 1:1 and mounts as wide as possible for maximum roll control. TCI part- nered with ‘RockJock’ for readily available replacement steering components that includes a Borgeson steering box, RockJock high-steer outer knuckles, forged tie rods, and front hubs based on the Jeep JL (2018-present) plat- form. Crucial steering angles and tie rod lengths were carefully designed to keep the bump steer in check and minimize lateral movement. Currie Enterprises ‘High Pinion’ Currie 44 front and ‘High Pinion’ Currie 60 axles using heavy duty axle tubes, yokes, chromoly axles and U- joints provide strength equal to the new chassis.
