What do you want to know about? Is there something we tried out in the pages of this magazine that you would like to know more about? Send an email to, and we'll make sure we get you an answer.

Crane Roller Rockers
We added a set of Crane Cams' roller rockers to a V-8 engine, a few months back, while doing some head work.

So far we've had no issues, and they make a nice addition that we think gave us a slight performance increase via increased efficiency. We say "think" because we swapped heads at the same time, so its hard to know if the performance improvements were due to the heads, the roller rockers, or a combination of both.

One thing we did need to get used to is that they are slightly noisier than the stock rocker arms. It's nothing bad, but you can hear the small difference with the hood open.

Nitto Trail Grapplers
Our tester cannot say enough things about these tires. He hasn't done too much street driving with them, but he raves about them in the dirt and mud on his CJ. A friend of ours also runs a 35-inch Trail Grappler on his 2500 Dodge diesel truck, and they've shown excellent wear patterns over the last six months.

In extreme clay mud, the tires can pack up a little, but a little excess throttle and the Trail Grapplers seem to clear themselves out again rather quickly.

The only complaint we've heard is that they weigh a lot-something that can be confirmed the first time you try to change one of them off your vehicle.

PSC Dodge Box
If there's one thing that has plagued '94-to-'01 Dodge owners (besides transmissions), it has to be the worn-out steering boxes. No one made a full replacement box for a long time, and that led to a lot of Dodges on the road with sloppy steering. We were able to get one of the first PSC replacement steering boxes for a Dodge, and it made our truck feel like a brand new one again.

It's held up great so far, and we still hammer on our Dodge as hard as ever.

We didn't opt for the hydraulic-assist version and solely rely upon just the steering box to turn the 37-inch tires on the truck. Any bigger, and we would have gone with hydraulic assist.

Powermaster Alternator
We've added a number of Powermaster alternators and starters to vehicles over the years, without a single issue yet (save for one wrong application-our fault, not theirs). Our most recent one went on about a year ago to replace a worn-out '90s factory 120-amp alternator. While our vehicle's electrical system was surviving with the original 120-amp alternator, it seemed to struggle when under load. Before the new alternator, we could watch the lights dim at night when the stereo's subwoofer hit. Now, it's hard to see any light change at all with the stereo on full blast and the new 170-amp alternator in place.
