Has anyone changed the rearend gears??

[HGW]

I have 4.88's in my Black H2 and there is a definate difference off the line with 40 inch tires installed. The H2 was a dog (already a dog with factory 35's) with 40's and 4.11's.

Gears are available up to 5.13 now for the front diff.

Be warned---few shops want to install them (4.88's and 5.13's) in the front---special tools are needed and they are expensive so almost no one has them. I can find you a guy from my race affiliations if you really want them done. PM me if necessary.

We had a bitch of a time doing our 4.88 install. So, watch the cost before changing gears. We now send them out because it is cheaper to have a guy do them who does it all the time. I am now buying front diffs so I can change them out with the new gears to reduce down time.

Usually gear changes are done when bigger tires are installed in order to return to stock performance off the line. The other reason is for 1/4 mile zing off the line and not many race the the 1/4 mile with an H2.

For the best zing per dollar see Klaus's post above.
