SPL Rear Mid Links (RML) replace the stock spring bucket arms to offer complete control over rear toe, rear spring rate, and ride height. The threaded spring perch accepts common 60mm ID springs and allows corner weighting with fine adjustment of ride height. The upper spring perch also has a linear adjustment range to match the spring location and reduce misalignment.We recommend pairing our midlinks with our eccentric lockout kit (ELT Z34) to eliminate the stock eccentric bolt, which can slip under significant load and ruin your alignment, leading to aggressive tire wear and poor handling in most cases. This also prevents the need to re-align the upper spring seat every time the eccentric is adjusted.Does not include springs.BenefitsLarge Range of Toe AdjustmentLightweight: 4.828 lbs (2.19 kg) per Side with Upper PerchesQuickly Change Rear Spring RatesAdjust Rear Ride HeightLess Rear Toe Change from Bushing DeflectionMaintenance-Free, US Made, PTFE-Lined FK BearingsMaterials6061-T6 Aluminum Arm Body6061-T6 Aluminum Spacers & Spring Alignment Pucks4130 Chromoly Steel Double Adjuster304 Stainless Steel Spring SeatsTi-6Al-4V Titanium Hardware (Anodized Blue)Swift 60mm Spring Thrust Washers
