P&H side frames have been proven in severe duty applications. This same engineering and manufacturing expertise has now been applied to the design of non-P&H structures, models 495HR, 495HF and 7495. FEA and strain gauge studies helped drive design improvements, resulting in an improved structural life of up to 60,000 hours. Upgrades can be supplied in the multiple configurations including bare frames, assembled with OEM equivalent components, and with the 10-inch or 11-inch Delta conversion with grease lines and covers.
