Total Chaos Fabrication's Gen II Caddy Kit
The off-road performance of '86 and newer IFS Toyota trucks leaves a lot to be desired, especially when compared to the earlier-model straight-axle trucks. We prefer to build our trails rigs with straight-axles too, but wondered if we could build a more versatile long-travel IFS setup that would perform well off-road without compromising the ride quality or on-road ride quality.
Total Chaos Fabrication of Corona, CA, has been building desert-racing-inspired IFS systems for over a decade. Their Gen. II Caddy Kit for '86-95 4WD Toyota trucks increases wheel-travel and tire clearance with minimal suspension lift to improve high-speed off-road performance. The Chrom-Moly upper and lower A-arms are extended 3.25" per-side and use 2.5x8" stroke coil-over shocks to dampen 12" of wheel-travel without eliminating four-wheel drive. The setup clears 33" tires (with fiberglass fenders) and is adjustable to achieve anywhere between 2-4" lift. As a secondary benefit, these suspension modifications actually improve the ride quality and the truck should handle better than stock. We ordered a Gen II Caddy Kit from Off-Road Warehouse to install on a '89 4Runner to compare the performance of an IFS overhaul to a straight-axle conversion.
All of the components included in the Total Chaos Gen II Caddy Kit are shown here. To complete the installation we ordered a pair of Sway-A-Way Racerunner 2.5x8" remote reservoir coil-over shocks and two 500x18" Eibach coil-springs. These race-quality coil-over shocks should allow us to really dial-in the spring-rate and shock-valving for a great ride and improved performance on/off-road.
Removing the stock suspension components on any older truck is a wild card. Almost every bolt and bushing in the front-end of our truck was seized in place. After removing the shocks from our `89 4Runner, we still couldn't cycle the stock suspension through its limited range of travel because the factory bushings were so worn-out and dried-up that they were holding the suspension in place.
