Dunno if you're on about 'Geartorque'???? If so, i wouldn't touch em....had so much trouble from them when i bought one of their boxes! First one they sent had a cracked casing.....2nd one appeared ok but when fitted all the seals leaked covering a brand new clutch in oil! As well as this the 2nd box wasn't a true rst box, and they tried blamin the leaks on the qualified mechanic who fitted it! Got another one out of em in the end....promised compensation for the £££ i spent gettin em fitted, delivery charges, hassle etc but never saw a penny! worst service and attitude i've ever had!
