The maXpeedingrods Frame Shortening Set is the only listed product that matches a truck long-bed-to-short-bed conversion. It is specified for 1963–1972 Chevy and GMC C10 trucks and converts a 128-inch wheelbase to 115 inches. The other listed products are mattress bridges or bed-frame brackets, not truck conversion parts, so they are not suitable alternatives.
| Product | Best For | Key Fitment Detail |
|---|---|---|
| maXpeedingrods Frame Shortening Set | Eligible Chevy and GMC C10 trucks | 128-inch to 115-inch wheelbase; not for 133-inch wheelbase or 4×4 trucks |
maXpeedingrods C10 Frame Shortening Set
Best for: Owners of a listed 1963–1972 Chevy or GMC C10 who are converting a 128-inch-wheelbase truck to a 115-inch wheelbase. It is the most relevant selection because its stated application is frame shortening for a short-bed conversion, rather than adjusting a household bed.
The product information also says the set fits 3/4-ton coil-spring trucks. For 1967–1972 3/4-ton trucks, it specifies that cab mounts must be changed to 1/2-ton C10 mounts. Confirm the truck’s year, configuration, wheelbase, and drivetrain before ordering; the model name alone is not enough to establish fitment.
Limitation: The listed information says it will not work on 133-inch-wheelbase trucks or 4×4 trucks. It also does not describe installation steps, included hardware, or other modifications, so verify those details with the seller or a qualified truck-frame professional before starting work.
Why it was selected: Among the supplied products, this is the only one intended for a vehicle frame and explicitly identified as a short-bed conversion kit. The other products are for connecting mattresses or adapting bed frames and should not be treated as automotive parts.
Buying Guide: What To Check Before Choosing A Conversion Kit
Does the kit match your truck’s wheelbase?
Start by identifying the truck’s actual wheelbase and comparing it with the kit’s stated application. This set is described for converting 128 inches to 115 inches. It is specifically excluded from use on 133-inch-wheelbase trucks. Do not assume that every long-bed truck has the same starting wheelbase or that a kit described for one measurement will fit another.
Is your truck within the listed year and model range?
Check the model year and whether the truck is a Chevy or GMC C10. The listed range is 1963–1972. The product information also mentions 3/4-ton coil-spring trucks, but provides an additional cab-mount requirement for 1967–1972 3/4-ton trucks: they need 1/2-ton C10 cab mounts. Confirm the details for the exact vehicle before purchase.
Is the truck two-wheel drive or four-wheel drive?
The listed kit will not work on 4×4 trucks. If the truck has four-wheel drive, do not assume this product can be adapted. Seek a conversion solution specifically documented for that drivetrain and configuration.
What should you verify about installation?
Frame shortening is a major vehicle modification. The product information supplied here does not specify the complete installation procedure, required tools, included components, or any additional changes beyond the cab-mount note. Ask the seller what the set contains and consult a qualified frame or restoration professional to assess the work before beginning.
Are the other listed “bed” products alternatives?
No. The FeelAtHome and HITOMEN products, along with the other supplied bed items, are designed for mattresses or household bed frames. Their features describe mattress connectors, straps, gap fillers, or furniture brackets. They do not convert a truck frame from long-bed to short-bed dimensions.
