Camaro Steering:The GM steering system is quite solid with few weak links. The gear boxes vary and the prefered steering box was introduced on the IROC Camaro. The Z28 version was also quite good. These two steering boxes use a "quick ratio" which allows the driver to turn the steering wheel fewer times to achieve a tighter turn.
One weak link in the GM steering system seams to be the steering hose itself. Hotchkis also has a tie rod sleeve which is a complete cylinder as opposed to the split sleeve which GM uses on the stock Camaro. This performance sleeve is stiffer, eliminating flexibility in the steering sytem to maintain tighter steering control.
Chevy Camaro Third Gen Steering boxes:
Two basic models were available, the 605 (bad small gear unit) and 800 (good) series. The two are swapable and mount identically. The best of the 800 series were the quick ration 14:1 Z/28, IROC, Trans Am variety. The steering box can be identified by the two letter markings stamped on both the box cover and the end cap.

Use Pitman arm GM# 7837642 for 800 series steering box.
The thicknes of the internal stops varied based on the size of tires offered by GM thus resulting in different degrees of angular travel.
Measuring Steering Box ratio: This is the ratio of the number of turns of the steering wheel to one complete turn of of the output shaft. Since the output shaft does not complete one revolution, just measure the percentage of a complete turn for the calculation and use the number of turns of the steering wheel from "lock to lock" (full left to full right or vice versa). In order to measure the number of degrees of output turn, use the following degree wheel.
Part #: 1601
These tie rod sleeves are substantially more rigid.

This set-up has never had a hose leak yet. It is industrial strength. The fittings are used on the steering box and on the GM power steering pump. The 90 degree hose end was used to attach to the fitting on the power steering pump. Hose fittings are SAE 37 degree AN fitting -6.
High engine RPM and the restriction caused by the hose aften leads to higher fluid running temperatures which can be remedied by using a cooler, a larger steering pump pulley or both. A larger pulley may hurt parking maneuvers which are performed at low engine RPM.
