How to Read a Belltech Part Number

Open our lowering kit page and you'll see the same truck listed three times with almost the same number. Same drop, same truck, three prices. The difference sits in the last two letters.

The base number

A plain number is the kit without shocks. Take the 1996 to 2004 Toyota Tacoma kit, P/N 443. The title says it's a lowering kit without shocks, with a 2 inch front and 3 inch rear drop for all cabs.

The suffix

Add letters and you've added shocks. P/N 443SP is the same kit with Street Performance shocks, and P/N 443ND is the same kit with Nitro Drop II shocks. Newer trucks sometimes use struts instead, and the title says so. On the 2019 to 2025 Silverado and Sierra, P/N 1040SP is a lowering kit with Street Performance shocks.

The rest of the title

Every Belltech title on our site follows the same order: the kit type, the shock choice, the drop, the vehicle and years, then the part number. Read the drop as front first, so 2" F / 4" R means two inches off the front and four off the rear. Cab style (Std, Ext, Crew or All Cabs) and 2WD or 4WD can change which part number fits.

Use the title to check three things before you order: your year, your cab and your drive type. If any of them is off, the kit won't bolt up. Browse the full list on our Lowering Kits page. Want to know how the kit will feel? What a Belltech lowering kit does to your ride covers that.
