Andersen Hitches Rapid Jack 3620

Published · Researched 2026-09-21

2026 lineup note: Current. The Rapid Jack (part #3620) is Andersen Hitches' drive-on tandem-axle tire ramp: drive the good tire up and the flat comes off the ground — no bottle jack, no crawling. Rated for trailers up to 30,000 lb with up to 5.75 in of lift. Manufacturer price $69.99 (in stock, Sept 2026). Do not confuse with Andersen's newer Single Axle Rapid Jack, a different, smaller product.

Version lineage (2023–2026)

• Pre-2023: Rapid Jack 3620 — the original red wedge; "the fastest jack around" per Andersen. Core design unchanged for years: 17 in long, 6 in wide, 7 in tall molded recycled-plastic wedge with rubber grip, doubles as wheel chock, jack wheel holder, jack post block, and pad block.
• 2023–2026: Rapid Jack 3620 (current) — same part number, same design. Current manufacturer specs: trailers up to 30,000 lb, lifts up to 5.75 in, 17 × 6 × 7 in. Made in USA. Marketplace listings show spec drift (see Buying traps) but the product itself is unchanged.
• 2026: Single Axle Rapid Jack — new smaller sibling for single-axle trailers; not the 3620. When shopping, confirm part #3620.

Overview

The Rapid Jack replaces the roadside bottle-jack routine on multi-axle trailers: place the small end under the closest good tire, drive forward, and the flat tire on the other axle lifts off the ground for a change. It also works as a single-axle leveler, a tongue-jack base (turned on its side, shaft in the molded circle), and a wheel chock. Molded from recycled plastic with a rubber grip pad, it resists dirt, grease, and oil and keeps the user out of the dirt. The catch the community keeps repeating: whether you get enough lift depends on axle spacing, suspension travel, tire size/inflation, and which axle you're lifting — test it at home before you need it on the shoulder.

Key Specs

Pricing

• Manufacturer price: $69.99 — andersenhitches.com, in stock (Sept 2026).
• Street price: ~$52–70 USD at RV parts dealers (Sept 2026); Canadian listings around $69.99 CAD. Prices in USD, September 2026.

In the Box

One Rapid Jack 3620 wedge with rubber grip pad. (Some retail bundles add bumper stickers — 3620-GFB — same tool.) Pairs with Andersen's TUFF Chock (#3605) for extra support when unhooking on the Rapid Jack.

Warranty

Conflict UNVERIFIED: resellers variously claim "lifetime part replacement (just pay shipping)" (RMH RV Parts, LawnPartsMan, ArrKann), 3-year limited (HitchStop), or 1-year limited (Adventure RV, Hitch Warehouse). Andersen's current official warranty terms were not captured in this research — re-verify at andersenhitches.com before publishing.

Support & Parts

Andersen Hitches (Idaho Falls, ID) sells direct with phone support. Because the product is a single molded piece, "parts" mostly means warranty replacement of the whole wedge; the rubber grip pad is the only wear item. Long product support window — the 3620 has been sold for years without revision.

Community Verdict

The Rapid Jack is genuinely popular with tandem-axle owners — "a major save on time, convenience & safety" in one Escape Forum roadside account (brake lockup in a parking lot, back on the road in 40 minutes). But the forums are equally full of fit caveats: Good Sam and My Grand RV owners report it sometimes doesn't lift high enough (long equalizers, soft suspension, or small tires eat the 5.75 in), with the standard fix being a 2×6 board under the wedge. A former tire tester on My Grand RV flags tire-load ratings — the grounded tire briefly carries the lifted axle's share — while others counter that static roadside loading is gentler than road shock. Several owners carry a small bottle jack as backup anyway. The Dexter Axle caution (a company rep advising against drive-up ramps for suspension reasons) circulates as the contrarian view. No fabricated scores.

Research date: 2026-09-21. Specs cross-verified across andersenhitches.com (current: 30,000 lb / 5.75 in / 17×6×7 in / $69.99) and current reseller listings (ArrKann, RMH RV Parts, HitchStop). Weight and warranty figures conflict across marketplaces — re-verify both at the manufacturer before publishing.

Long-term durability & warranty-claim reality (enrichment — Sept 2026)

It's a solid recycled-plastic wedge — there's almost nothing to fail. The long-term forum record is mostly positive, but Amazon reviews include reports of the plastic cracking under load, which is why the "lifetime part replacement, just pay shipping" reseller claim matters so much — if true, a cracked wedge is a cheap-shipping swap, not a rebuy. Andersen's polymer products (including the Camper Leveler) have a vocal minority of failure reports, so inspect the wedge for stress whitening or cracks annually, especially around the molded holes. UV exposure is the slow killer for any plastic left on a trailer tongue — store it out of the sun. Warranty-claim reality is the open question here: the 1-year vs 3-year vs lifetime conflict across resellers means buyers should screenshot the warranty terms at purchase.

Version history — year by year (enrichment — Sept 2026)

• 2023: Rapid Jack 3620 established as the tandem-axle standard; unchanged hardware.
• 2024: Continued; marketplace spec drift appears (lift quoted as 5.75, 7, or 8 in depending on listing — 5.75 in is the manufacturer figure).
• 2025: Continued unchanged.
• 2026: Continued at $69.99; new Single Axle Rapid Jack sibling introduced — verify part #3620 when ordering. No revision to the 3620 announced as of Sept 2026.

Head-to-head vs closest rivals (enrichment — Sept 2026)

• vs Andersen Camper Leveler (/library/gear/rv-essentials/andersen-camper-leveler/): same brand, same red polymer — the Leveler is the curved wedge pair for side-to-side leveling; the Rapid Jack is the tall single wedge for tire changes. Escape Forum owners commonly buy one of each instead of a bottle jack. The Leveler will not lift a tire for a change; the Rapid Jack will not level a multi-axle trailer (too large to fit between tires).
• vs Camco Curved Leveler 44423 (/library/gear/rv-essentials/camco-curved-leveler-44423/): Camco's curved leveling wedge — cheaper, aimed purely at leveling, not tire changes. For the tire-change job the Rapid Jack has no direct Camco equivalent.
• vs BAL X-Chock (/library/gear/rv-essentials/bal-x-chock/): the X-Chock locks tandem tires against each other to stop rocking — a stabilizer, not a jack. Complementary: X-Chocks for stability at camp, Rapid Jack for the flat-tire emergency. Both live in the "between the tires" space.

Care & maintenance (enrichment — Sept 2026)

Hose off road grime; the plastic resists grease and oil. Check the rubber grip pad for wear — it's what keeps the wedge from skidding on concrete. Inspect for cracks or stress whitening before each towing season. Store out of UV. Keep a 2×6 board with it — the forums' universal accessory for when 5.75 in isn't quite enough.

Buying traps (enrichment — Sept 2026)

• Spec drift on marketplaces: listings quote 2 lb (Amazon — wrong), 16.5 lb / 24 in long / 35,000 lb (Hitch Warehouse — appears to describe a different product), and 8 in of lift (Adventure RV — older copy). Trust the manufacturer: 6 lb, 17×6×7 in, 5.75 in lift, 30,000 lb.
• Single Axle Rapid Jack is a different, newer product — if the listing doesn't say part #3620, it's not this tool.
• Test at home: multiple owners' #1 regret is discovering the lift shortfall on the shoulder. Roll onto it in the driveway with the trailer loaded as you tow it.
• Warranty roulette: 1-year vs 3-year vs lifetime claims vary by seller — confirm in writing before you need it.
• The Dexter Axle caution against drive-up ramps is worth reading before deciding; it's the serious counterargument.

Community Verdict — additional voices (enrichment — Sept 2026)

Additional sourced voices (Sept 2026): Good Sam Community review thread — one owner found even the highest setting wouldn't clear the tire (long center equalizer blamed); another prefers it to bottle jacks on highway shoulders ("large trucks going by are liable to blow your TT right off the bottle jack"); Escape Forum — "years ago we chose to buy one Andersen Rapid Jack and one Andersen Camper Leveler... you will not have to carry a bottle jack"; iRV2 — an owner who found lift insufficient carries a 2×6 plus a small floor jack as backup, and urges testing at home first; My Grand RV — the Trailer Aid comparison (Rapid Jack has more lift, no concrete-damaging cleats, but can skid where Trailer Aid's cleats grip) and the tire-load debate. No fabricated scores.

Key Specs gap-fill (enrichment — Sept 2026)

Weights in both units: 6 lb = 96 oz = 2,722 g (consistent across ArrKann, RMH RV Parts, HitchStop, LawnPartsMan current listings; Amazon's 2 lb and Hitch Warehouse's 16.5 lb figures are treated as listing errors). Dimensions 17 × 6 × 7 in; lift 5.75 in; rated for trailers to 30,000 lb (13,608 kg). UNVERIFIED against the manufacturer's own published weight — re-check andersenhitches.com.
