STEERING

Quick Steer Power Steering Set Up

Power steering in a vintage racing Corvette makes the car way easier to drive, and you can run more positive caster with power steering. This is also a faster box; reducing lock-to-lock turns by a fourth. These cars are happiest with 6 or more degrees of positive caster. Unless your driver is a twenty something gym rat, he or she is not going to be able to handle much more than about 4.5 degrees of positive caster in a vintage Corvette without power steering. This is not the original 50's era Corvette power steering set up. It is a new US made quick steer gearbox that incorporates the function of both the original control valve and slave cylinder. We modify the internal valving in the stock racing pump to mute the power steering assist, providing the driver with proper racecar feedback.

The gearbox bolts to the original location and uses the stock pitman arm. The other major component is a modern compact hydraulic pump. We supply the pump, reservoir, pump pulley and standard head cylinder mount. The special high pressure braided stainless steel lines and fittings are included as well. We will email you for some additional information in order to supply the proper cylinder head pump mount. You will have to supply your drive pulley and belt. If you are using stock heads that have no cylinder head mounting holes, let us know and we can make a custom bracket for you at additional cost.

Big Block Custom Drag Link

Depending on your custom racing oil pan, there is often a lack of clearance with the stock drag link. This is a new drag link that has been modified to allow for additional clearance in the span between the inboard tie rod mounting bosses. This drag link is stronger than the original, and has exactly the same steering geometry. Includes all new hardware.

Roller Bearing Idler Arm

Long ago we found the stock idler arm was not up to the loads we put on our steering system during competition. After as little as one race weekend the stock idler arm introduces errors in the steering that upsets the bump steer. This is a CNC machined 4130 steel assembly that rotates on Timken steel ball bearings. We wouldn't build a car without one. It is expensive because of the CNC time it takes to machine this part out of solid 4130.

Non-Adjustable Bump Steer Block Assemblies

We manufacture the aluminum portion of this assembly and supply the correct steering knuckles and the hardware to put it together. The 6061-T6 aluminum block is machined to accept a stock tapered tie rod end. Every car varies , but this geometry will reduce the bump steer on your C2/C3 racecar, which will tend to stabilize the car under braking.

Adjustable Bump Steer Block Assemblies

The 6061-T6 aluminum block in this assembly is threaded to accept a Howe adjustable tie rod end. Since every car is different, it is necessary to fine tune the vertical position of the outer tie rod end to minimize bump steer. The RS540 blocks will get you close, but patience and these adjustable tie rod ends will get you as close as possible to zero bump steer over the full range of front suspension travel. Threaded Howe tie rod ends are included.
