YakAttack GTTL90 GearTrac. Grab the newest version of the GT90 GearTrac. The GTTL90 is the top loading version of the incredibly popular GT90. With a slimmer foot print and single hardware mounting line you can fit these in places that you wouldn’t be able to fit the GTTL175. Even though they are skinner, the GTTL90 tracks provide the same versitility and capabilites as the 175 versions. These GearTracs are what our shop pro uses and suggests for most installations we do here at the shop. Made from aluminium they can stand up to the harsh marine conditions.
