Thank You . on your response.. it would be the ideal gadget if it would work consistently trial and Error . Di you let know one else drive your truck and get there Opinions.? Just trying to see if it would be worth spending a day at the track Testing. The local Track Owner just Built a Brand New Factory Team B4.1 kit and put a Gear Diff in Using 5000wt Diff Lube With a Tekin Rs Pro And a 7.5 And it looked pretty Good . I'll see if I can Drive it to see how it performs ..
