The Floor Jack Extension is a great add-on when lifting vehicles whose jacking points are a little higher than normal, such as jeeps or lifted trucks. Compatible with MARTINS 3-Ton Floor Jacks (MFJ-P2T, MFJ-PL2T, MFJ-3T & MFJ-P3T), its 3" of height will allow to reach max. lift heights nearing up to 24", depending on the model. Ditch the wood or metal blocks or hockey pucks as jack extenders, our floor jack saddle extension is inexpensive and the safest option of all.
