We would like to announce an official change to our product – Torque Arm Insert – TSI 09+ :
After customer feedback and further testing, we have changed the durometer of the insert to 90a hardness (from its original 98a hardness). This puts this insert to the same hardness spec as our original Torque Arm Insert.
While we feel that the original insert performed well – some customers were unhappy with the increased vibration at low rpms – this slightly softer urethane reduces significantly the vibration while maintaining the performance of the insert.
Its original increase in hardness was to improve full load performance and offset it’s decreased available volumetric area vs. the original (’05-’08) insert. While some customers enjoy the increased performance of a harder material, some dislike its associated slightly increased Noise, Vibration and Harshness.
If you have purchased a previous version of the TSI 09+ insert and are dissatisfied with the NVH created by the mount we would like to extend an offer of a free replacement with the new version of the mount. Please send us an email to email@example.com and include your information as well as your original purchase order number.
