The supplied Pitman arm does not have any additional drop to it, therefore some applications may require a drag link flip kit.
The mounting pad of the BIG BORE XD has been up significantly reinforced to reduce frame flex, unwanted sector shaft deflection, and to prevent catastrophic failure of the case, resulting in a steering gearbox that weighs 15 LBS heavier than the OEM component.
WARNING:
Add HWK-688-PP hardware kit when installing any Synergy MFG Front Track Bar Brace (or similar) with this product.
Using the Factory or the PSC supplied bolts with a Synergy MFG Track Bar Brace could result in steering gearbox case failure.
The larger size of the BIG BORE XD Steering Gearbox may prohibit the use of some aftermarket track bars.
RECOMMENDED INSTALLATION NOTES:
The BIG BORE XD Steering Gearbox was designed to be used with a power steering pump capable of 1800 PSI.
PSC highly recommends the use of their HIGH FLOW/HIGH-PRESSURE Pump Kits to ensure system efficiency and extend component life. These pumps operate at approximately 1800 PSI and produce 50% more volume than the OEM pump. Vehicle steering performance will be diminished if a high mileage or remanufactured component is used.
Pitman Arm Retaining Nut Size: 46MM
HEMI Engine Conversions: If the AC compressor or power steering pump is located on the bottom driver side of the engine, there may be clearance issues.
GM LS3 Engine Conversions: The alternator will need to be modified for clearance.
