Equipment Modifications

• New mounting holes will need to be drilled
• In some models, there is a lip on the frame that will need to be trimmed for proper engine alignment
• In a small percentage of the kits we have sold (approximately 3%), we have been informed a cross member on the bed of the unit needed trimmed for engine clearance.
• If you have the 4x4 HPX, the parking brake caliper will cause a conflict with the new engine and will need removed for proper engine installation.
