thanks t .. yes i gained more height when i added the slotted plates for the bearings. which by the way are working awesome. just loosen the nuts on the plate bolts, a couple of turns on the tensioner bolt and the chain is adjusted. ( it only takes alittle turning because the top and bottom of the chain are both tightening..where as with a regular tensioner,your only pressing the slack side of the chain ) also it works without jacking up the tire. i could easily run 28 '' tires , but it's just fine with the 25'' tires and halftracks. just a different , fun design and much easier for me to work on if needed. j.b.
