When you are installing a modern front suspension system or swapping engines into a classic truck, engine placement is one of the most important parts of the build. The engine cannot simply sit “close enough.” It needs to be positioned correctly for firewall clearance, oil pan clearance, steering shaft routing, header fitment, transmission alignment, driveline angle, radiator placement, and overall serviceability.
That is exactly why CPP offers the Fit Rite™ Adjustable Motor Mounts with Polyplus™ Pads, part number CP11901. This adjustable motor mount kit is designed to help builders fine-tune engine placement when using compatible CPP Mustang II IFS systems. Instead of being locked into a fixed engine location, the CP11901 kit gives you added adjustment so you can better position the engine for your specific build.
Built for CPP Mustang II IFS Engine Installations
The CPP CP11901 Fit Rite™ Adjustable Motor Mounts are designed for use with CPP Mustang II IFS kits, including the E6579M2IFS-K application. These mounts are used to install various engine combinations and provide 2 inches of built-in adjustment for more precise engine positioning.
That adjustability can make a major difference during a custom installation. Classic trucks and engine swap projects often involve different engine blocks, oil pans, transmissions, headers, steering components, and firewall layouts. A fixed-position motor mount may not always place the engine exactly where it needs to be. With CPP’s Fit Rite™ design, builders have more room to make the engine fit the vehicle, not the other way around.
Why Adjustable Motor Mounts Matter
During an engine swap or front suspension upgrade, small changes in engine position can affect several areas of the build.
Moving the engine slightly forward, rearward, or into the ideal mounting location can help with:
- Firewall clearance
- Oil pan and crossmember clearance
- Header and exhaust routing
- Steering shaft clearance
- Transmission tunnel fitment
- Driveshaft and driveline angle
- Radiator and fan spacing
- Overall service access
The CP11901 adjustable motor mount kit helps reduce guesswork by giving the installer more flexibility during mockup and final assembly. For builders working on custom classic truck projects, that flexibility can save time and help create a cleaner, better-fitting installation.
Supports Multiple Engine Combinations
CPP designed the CP11901 kit to work with a range of popular engine combinations when paired with the correct CPP engine perches. Depending on the engine and perch combination, the CP11901 mounts can support installations for:
- Ford Small Block 289, 302, and 351 Windsor engines
- Rear sump Chevy Small Block engines
- LS engines
- Ford FE engines
- Front sump Ford FE applications with the correct tall perches
This makes the kit a useful solution for builders who are upgrading a classic Ford truck with a CPP Mustang II IFS system and need a motor mount setup that works with the engine combination they have planned.
Includes CPP Polyplus™ Pads
The CP11901 kit also includes CPP Polyplus™ pads, which help secure the engine while absorbing vibration. Compared to old, worn rubber mounts, Polyplus™ pads are a smart upgrade for performance builds, restomods, and street-driven classics where strength, durability, and drivability all matter. The goal is to help control engine movement without creating a harsh driving experience. For classic trucks that are being upgraded for better handling, improved steering, and modern drivability, a stable engine mounting system is an important part of the overall package.
A Better Solution for Custom Builds
No two classic truck builds are exactly the same. Even when using the same basic suspension kit, one truck may have a different engine, transmission, oil pan, header setup, steering shaft layout, or cooling system than another. That is why adjustable mounting solutions are so valuable.
The CPP Fit Rite™ Adjustable Motor Mounts help builders account for those real-world differences during installation. The 2 inches of adjustment gives you room to fine-tune the engine location before everything is tightened down and final fitment is confirmed. Before final assembly, it is always a good idea to mock up the engine and transmission, check all major clearances, verify driveline angle, and confirm that the correct CPP engine perches are being used for the specific engine application.
