Can-Am Defender lift kit: 3" vs 5" vs 8" — which one do you need?
Choosing a Can-Am Defender lift kit is less about one “best” height and more about tire size, machine width, and how hard you use the machine. CATVOS builds Defender suspension in Shreveport, Louisiana. Browse the arm-style kits on the Can-Am Defender collection, and confirm fitment on each product page before you order.
3" kits: built into the arms, not shock spacers
The 2020–2024 64" adjustable 3" lift fits 64" wide Defenders with 11.5" factory tie rods and lists clearance up to a 35" tire. The 3" lift is built into the arms (no shock brackets). It includes front camber and caster adjustable upper and lower control arms with plus-3" forward offset, rear lower adjustable camber arms, and heavy-duty steering with chromoly rod ends. Arms use USA .250 wall DOM tubing and 5/8" thick ball joint plates, with a lifetime warranty as stated on that page.
For 65" wide XMR / Limited / Lone Star machines (13" factory tie rods on the listing), see the 3" lift with 3" forward arms and HD steering. That page states clearance up to a 37" tire, or up to 46" with 8" portals, USA .250 wall DOM tubing, camber-adjustable 3/4" chromoly pivot tubes, chromoly steering ends, and a lifetime warranty.
If you want bushings, ball joints, steering, and frame supports in one box, the CATVOS 3" complete package is a full upgrade for 65" Defenders: 3" lift built into the arms, 3" forward offset for up to 37" tires, UHMW bushings, Mega Compression ball joints pre-installed, heavy-duty steering, front and rear frame supports, spring spacers, steering stops, steel bed hinges, sway bar mounts, black powder coat, and a lifetime suspension warranty. TIG welded from USA .250 wall DOM with 5/8" ball joint plates. That page contrasts this kit with spacer lifts that only raise the shocks and usually max out around 27–28" tires.
5" kits: portal-ready height
The Defender 5" lift (2016 and up) is a complete portal-ready suspension backed by a lifetime warranty. It includes arched plus-3" forward adjustable camber arms, chromoly rod ends on the adjustable lowers, laser-cut shock relocation brackets, an exhaust flange for relocated rear shocks, clevis-style DOM steering, and spring spacers. The page states it clears a 37" tire without portals. Specify year and model in the order notes.
For 65" XMR / Lonestar / Max XT cab machines, the XMR 5" lift follows the same portal-ready story and 37" tire claim without portals, with a lifetime warranty on fabricated parts. The listing tells 62" or 64" owners to use the other 5" Defender page.
8" and HD11: big tires and heavier tube
The CATVOS 8" Defender lift is labeled Gen 3 for 2026 and ready for big portals and big tires. It lists adjustable camber lowers with 3/4" chromoly rod ends, heavy-duty clevis steering, laser-cut shock relocation, optional ball joint delete hardware, Mega Compression ball joints when delete is not selected, 1.5" OD .280 wall USA DOM tubing, and a CATVOS lifetime warranty. Specify year and model when ordering.
The Defender HD11 complete kit lists 1.75" OD arms with 1/4" wall DOM, front arms shifted 3" forward, rear arms raked 3" backward for a longer wheelbase, 1-1/4" chromoly-ended steering rods, 7/8" heims, Mega Compression ball joints and UHMW bushings pre-installed, and clearance up to 40" tires.
