Question: I'm looking at the new FJ cruiser, but I would rather have a convertible version. Do you know if Toyota is planning such a version next year? I would rather suck it up another year to get a topless version.

Answer: We've heard those rumors of a topless FJ too, but we would be surprised if it's coming any time soon. After driving our Ultimate FJ a small bit, we can see the value of a soft-top version since the hard cab has a fair bit of blind spots. However, if you look at the new FJ, you'll notice that the front and rear doors open with no center pillar which results in almost 5 feet of negative space in the body, and without the roof the body would lose quite a bit of structural integrity. We would expect some sort of large sunroof, and maybe a soft top down the road a few years, but if you're hungry for an FJ, get the hardtop version for now.
Question: I have an '03 F-350 with 6.5-inch Pro Comp springs and a Power Stroke that rides like crud on the highway. If the road has multi breaks in the pavement the truck feels like it is going to bounce your fillings out. I was wondering if a dual-shock setup would help or maybe a set of Fox shocks. I am willing to spend the money on anything as long as it works.

Answer: Many issues could be causing this abusive ride. I discussed this with the engineers at Donahoe Racing (714.632.3033) since they have a Ford Super Duty that they race in the stock fullsize class off-road and we came up with the following options. Lower the tire pressure 10 psi below what you currently have it set at (we assume they are filled to max load pressure) and see how it affects the ride. This can hurt your mileage and tire wear, but it doesn't hurt to use the tires as a small part of your suspension. Second, if a loaded bed gives a better ride, then you may need some softer springs for a good ride when it's empty. Contact manufacturers like Donahoe, Pro Comp, and so on and ask them for their spring rates, especially on the rear springs, then make your choice based on the lowest rates. Just remember that softer springs can reduce your load-carrying ability and towing capacity. Finally, get a shock that is properly tuned for your specific truck. Going to dual shocks is OK, but not as helpful as a quality shock that has been tuned to the weight, spring rate, and usage of your truck. Again, manufacturers like Donahoe, Fox, Bilstein, or Walker Evans Racing can address these.
On a side note, check that all the bolts holding your bed to the frame are tight. Sometimes over extended use, or when spray-in bedliner is applied the bolts are loosened and not sufficiently retorqued. The bed is an important part of the frame stiffness, and if the frame flexes too much, it won't allow the suspension to do its job of dampening the road.
Question: Is there anyone who has put a diesel in a Bronco, and if so, is there even a starter kit to help me with this swap? I know this would be a big swap, but I think it would be great in the long run.

Question: I have a '77 F-250 Ranger I want to put a Cummins diesel in. I have a good shop to work in and I'm also an apprentice welder so any kit that involves fabrication or welding I'm sure I'll be able to handle quite well.

Answer: Dave, meet Matty; Matty, meet Dave. OK, now that you are friends go check out www.cummins-conversion.com, www.fordcummins.com, and www.autoworldmt.com. These Web sites offer conversion kits and forums to discuss the swaps. Yes, it can be done, and these guys are your best resources.
Question: I have an '86 Toyota regular cab 4x4, and I would like to build a four-link suspension system on the front and back using Dana 44 axles from a mid-'70s Jeep Cherokee. I know I will probably have to shorten the axles but my biggest problem is where can I find technical info on how to custom fit a four-link; i.e., mathematical formulas and so on? Also, how do I choose coil springs for this system especially if I swap my 22R for a Chevy 350? When all is said and done I would like to clear 37- to 38-inch swampers with plenty of flex. I will be replacing my fenders with high-clearance fiberglass ones.

Answer: Well, Corn-Boy, there isn't really a simple explanation of four-link suspensions because of the many variables involved. Plus almost every suspension designer we've come across believes in a different design. A few years back I wrote an article about building your own four-link rear suspension and it is now available on our Web site (www.4wheeloffroad.com) under the suspension portion of the 4x4 Tech section, and though this is a proven design, there are many variants possible for your particular vehicle. However, I recently found out that Shaffer's Off Road (775.885.9944) would be offering a weld-on linked suspension system designed for Toyota pickups and 4Runners. If you want a kit with most of the hard stuff figured out and just a bit of welding to do, give Shaffer's a call.
