Description
TRQ suspension kits are manufactured using premium raw materials and coatings for extended service life. Each TRQ suspension component is designed to be a direct, maintenance-free replacement to the stock unit. To extend the life of your steering and suspension components, TRQ recommends replacing components in pairs, sets, or kits. All products are fit and road-tested in our Massachusetts R&D facility to ensure we deliver on our promise of Trusted Reliable Quality.
Install Tip: When replacing steering components, have a professional alignment performed afterwards. This ensures proper tracking and even tire wear.
Our steering and suspension components are pre-greased and sealed for long life and do not require the extra maintenance typically required by greaseable versions.
