RJSPHH RV Slideout Gearbox R25076-1 — 13-Tooth Sprocket with Mounting Bracket, Aluminum/Iron Durability

RJSPHH R25076-1 is a heavy-duty replacement slideout gearbox with a 13-tooth sprocket and integrated mounting bracket designed to restore smooth extension and retraction of RV and trailer slide-outs.

If your motorhome or travel trailer slide-out is sticking, grinding, or refusing to move, replacing the gearbox with a robust, purpose-built unit can get the room moving reliably again. The R25076-1 pairs a 13-tooth sprocket with a fitted mounting bracket and is built from a mix of aluminum and iron to balance light weight with structural strength. It’s sold as a direct replacement part and comes with a one-year warranty for added confidence during installation and early service life.

How will this gearbox improve my RV slide-out's performance?

The RJSPHH R25076-1 gearbox restores the mechanical link between motor and slide mechanism, eliminating slippage and reducing uneven motion. Its metal construction resists deformation under load so the sprocket teeth maintain engagement with the chain or gear track longer than softer components.

• 13-tooth sprocket ensures consistent engagement with common slideout chains
• Aluminum housing reduces weight while iron components add durability
• Precision-machined teeth minimize noise and judder

Is this gearbox compatible with my RV or trailer model?

Compatibility depends on matching the reference number, mounting pattern, and sprocket tooth count to your existing assembly. The RJSPHH R25076-1 is intended as a replacement for gearboxes listed under reference R25076/R25076-1, and it uses a 13-tooth configuration commonly found on many slide-out systems.

• Reference numbers: R25076, R25076-1 — match to your current part
• 13-tooth sprocket — verify tooth count on your old gearbox
• Includes mounting bracket — check bolt pattern and clearance before ordering

What should I expect during installation and maintenance?

Installation typically involves removing the old gearbox, aligning the new unit with the drive motor and slide mechanism, and securing it with the provided bracket bolts. Routine checks and light lubrication of moving parts will extend life and preserve smooth operation.

• Basic hand tools required; some models need access panels removed
• Ensure correct alignment to avoid premature wear on sprocket teeth
• Inspect and lightly lubricate chain or gear teeth during installation

Who is this for? The RJSPHH R25076-1 is intended for RV and trailer owners, independent technicians, and fleet maintenance teams who need a durable, direct-replacement slide-out gearbox. Choose this part if your unit’s reference number matches R25076 or R25076-1, if the existing sprocket has 13 teeth, and if you require a metal-bodied gearbox with an included mounting bracket and a one-year warranty. It’s a practical option for repairs where reliable mechanical engagement and long-term durability are priorities.
