I have them on my BL Revo. Before I got them I was rebuilding broken diff parts almost every time I ran. Since getting these I havent had a single problem. They are the best Revo upgrade ever made. Worth every penny IMO.

I run mine with the adapters for the stock revo sliders. If you use the adapters for the stock slider driveshafts, you can drop them right into the bulkheads just like a stock diff. Its a little tighter fit but they do just drop in. If you run them with conventional outdrive cups for CVDs you will need to split the bulks to get them in, not a big deal, just a little more work to get them in and out.

I say do it. Rebuilding the diffs is a PITA which you will be doing frequently in a high power big block or BL setup.

Also as far as the price goes... Keep in mind that you are getting a complete hardened HB Diff and Pinion which are $62 by themselves, really the custum machined diff cases are only $63. When you see them you will see that $63 for the custom machined case is actually very fair price. lots of work went into to machining it, let alone the design and development of them.

One thing to keep in mind is that they do change your gear ratio from the stock ratio. The stock ratio is 2.84 (13/37)and the 1/8 are either 3.3(13/43) or 4.3 (10/43) depending on which gear set you select.
