Hello everyone! Houston Speed Freaks has released their solid differential inserts for the Explorer ST.
Aimed at reducing differential movement, which contributes to better launching characteristics. They are crafted from 6061 aluminum. Pre-orders are open and expected to ship by the end of June.
According to HSF, they noticed no added additional NVH on their test vehicles. They do disclose “with that in mind, we do know that no two cars are alike. So you may experience some additional noise, vibration or harshness. These are race spec solid billet aluminum bushings For those that are looking to push their Explorer to the extreme.”
