Web research into the front differential housing of the 1995 Geo Tracker / Suzuki Sidekick, run to size the geo-tracker-front-diff-shield. The headline result is negative — the dimensions do not exist online. This note records that explicitly so the search is never re-run.
The Negative Result
Published dimensional data for the Sidekick/Tracker front differential housing does not appear to exist online
Checked and came up empty:
- Vendor product pages — Rocky Road Outfitters, Calmini. They sell front skid plates for this exact platform and still publish no housing dimensions.
- Specification pages — zukioffroad drivetrain spec listings.
- Forum threads — suzuki-forums and related.
None list housing length, width, height, or a cover bolt pattern.
Measuring off the vehicle is the only route. Do not spend more agent time searching for this.
What WAS Confirmed
These facts are sourced, not estimated.
The weak point (the reason for the part)
- The front axle housing is aluminium.
- Vendors state that a plate is essentially mandatory for offroad use.
Drivetrain
| Item | Value |
|---|---|
| Rear ring gear | 6.9 in, solid axle |
| Rear axleshafts | 26 spline |
| Final drive ratio | 5.12 (manual) / 4.62 (auto) |
| Transfer case | 1.82 low / 1.00 high |
Front axleshaft splines — sources conflict
- 1994 and older: 22 spline
- 1995 and up: 26 spline
Not fully settled
Sources conflict slightly on whether the front axleshafts actually made the 22 → 26 spline change, or whether the front stayed at 22 while the rear changed. Treat the front spline count as unconfirmed for a 1995 car until physically checked.
Aftermarket front skid plates (existing products)
| Vendor | Material |
|---|---|
| Rocky Road Outfitters | 10 gauge steel |
| Calmini | 3/16 in zinc-plated |
The alternative to shielding
Steel front housings from the Suzuki XL7 and Grand Vitara V6 are a known swap to replace the aluminium one outright. This is worth weighing against building a shield — it removes the failure mode rather than protecting it.

What This Means for the Model
Because no housing data exists, the geo-tracker-front-diff-shield was sized from a 230 mm assumed pumpkin sphere, itself derived from the rear 6.9 in ring gear plus assumed casting thickness. That chain of assumptions is the model’s single largest source of error.
