Doug i don't think you will gain more than .002/.003 with a change to 1.80's, maybe not worth the cost. I think the smaller tire from the 16X33's that you have been running will make the difference. I would try the smaller tires before spending $750.00/$850.00 on the gears.

thanks Zip, do you know i'am running a stock P/G planetary? i thought they might be weak? i have been using it the last 5 years. Right now i have a friend that works for a distributor of Toyo tires, he's going to find out what they have and i will go from there also i think i have a trade on my 15x16 wheels for 15x15 that will give me more tires to chose from, those Toyo's you have are the perfect roll out. I'll let you know what he finds. Thanks Doug

Either a 1.80 or 1.96. IMO one of the best investments people rarely make !

Default P/G

Fast Vega they make a 1.98 but someone told me they were not as strong as the 1.80? and the 1.80 set is $688 if the stock 1.76 is as strong as the aftermarket sets i might hold off as i just bought a set of Chad Speire heads, Jesel rocker bars and will buy a slicks soon also have to get the chassis certified $$$. I would like to know about the strength of the 1.98 planetary set to the 1.80. Thanks to all Doug

The 1.98 aftermarket is just as strong and made of the same material.

What you need to watch out for, some of the aftermarket gear sets are made of cheaper material and made over seas. Find one made in the USA ..

A 1.76 is no where near as strong as a 1.80
