Work Smarter with the RAT3213: One Kit, Every Lockbolt | Reliable Air Tools

If your shop handles both cab bodywork and trailer repair, you already know the math doesn't work in your favor. One job calls for Magna-Grip® fasteners on a cab panel, the next calls for C6® lockbolts in a completely different diameter for trailer skin, and somewhere in between a sleeper conversion shows up needing a blind fastener nose you didn't stock. Buying tools one job at a time is how a shop ends up with three half-equipped kits and none of them ready for whatever rolls in next.

Reliable Air Tools built the RAT3213 Cab / Trailer Kit to solve exactly that problem. It's the flagship of the 3/8" Capacity - Truck Cab & Trailer Repair lineup, and at $3,495 it's priced to be the last lockbolt tool your shop has to buy for cab and trailer work.

A Nose for Every Job, already in the Case

What separates this kit from a basic tool purchase is the nose set. The RAT3213 Cab / Trailer Kit (SKU RAT3213-T) ships ready to handle:

• 3/16" and 1/4" Magna-Grip® noses for cab body panel installation
• A 3/16" C6® nose for chrome grill bolts
• A 3/16"–1/4" Magna-Lok® blind fastener nose with reducing adapter, sized for sleeper conversions
• 5/16" and 3/8" C6® noses for trailer panel repair

Compare that to the bare RAT3213 Lockbolt Tool, and the value gap is obviousyou're not sourcing six noses separately after the fact. If your bay only ever sees cab work, the RAT3213 Complete Cab Kit covers that narrower scope for less, and trailer-only shops can start with the RAT3213 Basic Trailer Kit. But a shop pulling grill bolts on a Kenworth Monday and patching trailer panels Tuesday needs everything in one case, and that's this kit.

Specs That Hold Up Under Daily Use

This isn't a featherweight import tool that folds under repeat use. The body is aircraft-quality aluminium throughout forged on the pneumatic side, CNC-machined from a single billet on the hydraulic side with a chrome-moly steel pulling plunger doing the actual work. It's built in Taiwan with western-style seals, the same build philosophy we get into in Asian vs. American made lockbolts, where seal quality and machining tolerance matter a lot more than country of origin once you're past the marketing.

The numbers back it up:

• 7,500 lb. pull capacity at 110 psi (31kN at 7.7 bar)
• 0.51" stroke on 70–100 psi shop air
• 6”-cylinder diameter, 13.38" overall height, 6.4 lb. total weight
• Runs on standard DEXRON® III/VI, MERCON®, or Allison C-4 hydraulic fluid
• Rated for 32–125°F operating temperatures

That capacity and nose range put the RAT3213 in the same conversation as the Gage Bilt (New) 745 and Huck® Brand (Refurbished) 225, 245 and 255 it uses the same 1-1/16" diameter noses, so a crew trained on either platform picks this up without a learning curve.

Why Owner-Operators and Small Shops Standardize on It

Quoting a job gets a lot simpler when the nose is already in the case instead of on a backorder list. Whether it's a sleeper conversion, grill bolt replacement on a Peterbilt, or trailer panels after a dock accident, the RAT3213 Cab / Trailer Kit doesn't make you choose. We walk through this exact scenario in How to Use a Huck Rivet Gun for Restoring an Old Peterbilt: The Ultimate Workshop and A Complete Guide: How to Choose the Best Huck Rivet Gun for Your Peterbilt, both useful reading if you're still comparing options against the jobs your bay actually runs.

Mobile techs benefit just as much. Benefits of Having a Huck Truck Cab Kit on the Go covers why the same logic that makes this kit valuable in the shop matters even more when you're dispatched to a fleet yard with no parts counter for fifty miles.

Parts and Support That Don't End at Checkout

Noses wear out before the tool body does, and Reliable Air Tools keeps replacements stocked in Accessories so a worn jaw never takes a $3,495 tool out of service for long. If pulls start feeling inconsistent, our guide to fixing worn or tumbled jaws walks through the repair in a few minutes, no return shipping required.

Equip the Bay for Whatever Comes In
