This is a Mad Polly PU 92A Polyurethane Rear Slotted Engine Mount Insert upgrade for a Proton Satria, Gti, Jumbuck, Persona 4G93 engine 

These are specifically made as a performance upgrade so if you are considering modifying you’re engine then it may be a good idea to upgrade your mounts at some point too. 

Stiffer PU engine mounts will prevent excess engine movement, which will result in improved throttle response, easier gear shifts, better traction and improved steering response, etc… This is a must-item for sports driving

100% locally made in Queensland, Australia. Not a Chinese import!

Available are the ‘orange inserts’ and crush tube, which means you should NOT throw away your original metal casing, but simply heat up or cut out the original rubber, knock it out including the crush tube or cylinder, then replace it with our Mad Polly high performance PU item. 

*Please watch this video below for instructions on how to take out the original rubber insert and replace it with our item… 


If you are unsure how to do this it would be recommended to give it to your mechanic for them to do. 

Also available for pickup in Mudgeeraba, Gold Coast, QLD
