Kevin K.
A:BEST ANSWERHello Kevin- Since we do not have the engine size of your Ascender LS, please check this link for options of fittings that we have available. https://www.carparts.com/search?q=fitting&vehicle[submodel]=LS&vehicle[model]=Ascender&vehicle[make]=Isuzu&vehicle[year]=2006 Also to check for parts available for your car and the fitment please use our Vehicle Selector — which can be found towards the top of the homepage as well as all categories, search results, and product pages — can help verify if a part will fit your specific application. To enter your application, simply select your vehicle’s year, make, model, sub-model, and engine type and click “Go.” Once your application is selected, you’ll see a “Guaranteed to Fit” badge if the part will fit, and we recommend that you also double-check Your Vehicle Fit Details as well as the Vehicle Fitment Information table on the product page. Show less
