Outer Limits 4x4 Board

i need to replace the ring and pinion gears for my hilux / bundy diffs which are going under a sierra, they are currently a 4.33 ratio. I have seen the 5.29.1 gears on locktup http://locktup4x4.com.au/hilux-solid-fr ... r-611.html" onclick="window.open(this.href);return false; has anyone had experience with these or this brand? The car is not road driven.

Me and a mate both run gears 4.88 toyota 9,5 gears in our play rigs and have had no dramas mine survied Tuff Truck and Locktup are great too deal with.

Have had them in my jeep almost 2 years running fine, good pattern was easy to get and set!
