Mazda B4000 Alignment Caster & Camber Kit Guide (1994-2010)
If your B4000 is wearing out tires or pulling to one side, this is the part you need to fix it.
- Your B4000 requires an aftermarket caster/camber kit to perform a full front-end alignment, as it was not adjustable from the factory.
- A professional alignment is mandatory immediately after installing the kit; the installation itself can be done by a DIYer, but the adjustment cannot.
- Before installing, ensure other suspension components like ball joints and control arm bushings are in good condition, as worn parts will prevent a successful alignment.
- Parts for the Ford Ranger of the same year are interchangeable, which greatly expands your options.
Your Truck's Built-In Alignment Problem
If an alignment shop has told you they can't properly align your Mazda B4000, they're not trying to upsell you. The 1994-2010 Mazda B4000, a mechanical twin to the Ford Ranger, came from the factory with fixed, non-adjustable bolts on the front upper control arms. This means there is no factory way to adjust the caster and camber angles. While this setup works when the truck is new, any suspension wear, damage, or modification (like lifting or lowering) can throw these angles out of spec, with no way to correct them.
An aftermarket Caster / Camber Kit is the solution. It replaces the stock bolts with eccentric cam bolts, making adjustment possible so you can stop wearing out tires and fix steering pull.

The symptoms aren't from the kit failing, but from the lack of one. If you notice the following issues, and an alignment shop can't fix them, you almost certainly need to have a kit installed.
- Uneven Tire Wear: The most common sign is the outer or inner edge of your front tires wearing down much faster than the rest of the tread.
- Vehicle Pulling: The truck consistently drifts or pulls to the left or right when you are trying to drive straight.
- Off-Center Steering Wheel: To drive straight, your steering wheel has to be turned at a slight angle. 🎬 See this breakdown of common bad wheel alignment symptoms.
- After Suspension Work: It is essential to install a kit if you replace control arms, ball joints, or change the ride height with a lift or leveling kit.

Pro Tip: Get the Right Amount of Adjustment
These kits are sold by the degree of adjustment they offer (e.g., +/- 1.5 degrees, +/- 2 degrees). For a stock truck with normal wear, a standard kit is usually sufficient. If your truck is lifted or has significant suspension sag, you may need a kit with a larger adjustment range. An alignment technician can tell you how far out of spec your truck is, which helps in choosing the right kit.
Frequently Asked Questions (FAQ)
Can I install this kit myself?
Yes, swapping the bolts is a straightforward job for a DIY mechanic with basic tools. However, installing the kit will make the alignment worse until it is professionally adjusted. You MUST take your truck to an alignment shop immediately after installing the bolts. For this reason, many owners have the alignment shop supply and install the kit at the same time as the alignment.
Why can't I just get a normal alignment?
A normal alignment only allows for "Toe" adjustment on these trucks. The Caster and Camber angles are fixed by the original factory bolts. If those angles are out of specification, this kit is the only way to make them adjustable and correct the alignment properly.
Should I replace anything else at the same time?
Yes. Before trying to fix your alignment, inspect your ball joints, control arm bushings, and wheel bearings. Worn-out parts will prevent the truck from holding an alignment even with this kit. If your other front-end parts are loose or worn, replace them first, then install this kit 🎬 Watch: How to replace upper control arms and ball joints. and get a final alignment.
Are there any recalls or TSBs for this?
No, there are no specific recalls or Technical Service Bulletins (TSBs) from Mazda or NHTSA for the alignment bolts on the 1994-2010 B4000. The need for this kit is due to the original factory design, not a defect.
