4.10 FORD 8.8" PERFORMANCE SERIES FORD RACINGThomas MDecember 23, 2012Just installed them on my 07 GT and wow. Puts you in the powerband every gear. At 2500 rpm at 70. And best part got rid of my droning at highway speeds with the o/r h and mac mufflers. Highly recommend for anyone with a manual 05-10 mustang.
4.10 FORD 8.8" PERFORMANCE SERIES FORD RACINGJohnJuly 10, 2010Best mod for your money, It dropped me almost a full second! (.9) which is outstanding. if you combine this with the sct x3 custom tune, your car just wants to pull! so damn bad thanks brenspeed!
4.10 FORD 8.8" PERFORMANCE SERIES FORD RACINGjakeMay 26, 2010I had these installed in my 07gt automatic and it really woke the car up. Lots of people say that auto's are great with 373 and i think 410s are a must have. Brenspeed had these installed before the afternoon and my car ran great. Thanks guys im looking forward to getting my cams installed
4.10 FORD 8.8" PERFORMANCE SERIES FORD RACINGJohn KMay 2, 2010these gears are amazing! Im stepping up from a 3.31 and wow these gears will make your car jump off the line. you can also get really sideways with traction control off ; ) DO NOT fear the 4.10s because of the gas milage. its entirely worth it! buy these!
4.10 FORD 8.8" PERFORMANCE SERIES FORD RACINGDerek C.March 12, 20092005 mustang gt....mods-BBK throttle body, SCT X3 tune, pypes muffler delete, K&N CAI, and NOW 4.10's!! The gears are by far the best mod I've done so far. No more bogging at all with low speed shifts! cruising at 65-70 puts me RIGHT in the best engine speed (2250 ish) with much less drone. the hit to the gas tank is completely worth it for what you get back. seriously consider this product if you want a huge leap in performance, and a huge boost of fun.
