Forward arms vs spacer lifts on the Can-Am Defender
Search results for “Can-Am Defender lift kit” are full of inexpensive spacer and bracket kits. Those parts have a place, but they are not the same job as forward control arms. CATVOS builds arm-style Defender suspension in the USA, and the product pages spell out why forward geometry matters when you care about tire clearance.
What a spacer-style lift actually changes
Spacer and simple bracket lifts mainly change shock or spring position to raise the body. That can help a mild tire bump, but control-arm length and pivot points stay closer to stock. On the CATVOS 3" complete package page, CATVOS contrasts arm-built kits with spacer kits that “only raise the shocks and usually max out around 27–28" tires.” You get height, not much new room for the tire to move forward in the wheel well, and less ability to tune camber and caster the way adjustable heims allow.
What forward arms change on a Defender
Forward arms relocate the front wheel forward relative to stock. That leading position opens clearance for taller tires with less fender or frame rub. Current CATVOS examples:
- Defender Plus 3" forward front arms — upper and lower 3" forward adjustable arms, listed to clear a 35" tire. USA-built with .250 wall DOM tubing, 5/8" thick ball joint plates, and 3/4" chromoly pivot tubes; uses factory-size bushings, stock axles, and ball joints; designed to run portals; lifetime warranty on the page. Fits all 65" wide Defenders including XMR, Lonestar, and Limited.
- 3" lift with 3" forward arms and HD steering — front camber/caster adjustable arms with +3" forward offset, rear lower adjustable camber arms, and chromoly steering ends. Clearance up to a 37" tire (or up to 46" with 8" portals), USA .250 wall DOM, 5/8" ball joint plates, 3/4" chromoly pivot tubes, and a lifetime warranty. The 3" lift is built into the arms.
- 64" adjustable 3" lift — plus-3" forward offset with the 3" lift built into the arms (no shock brackets), up to a 35" tire, USA .250 wall DOM, chromoly steering ends, lifetime warranty.
Materials you can verify on the product pages
- USA .250 wall DOM tubing on the plus-forward arms, 3" kits, and complete package (the 8" kit lists 1.5" OD .280 wall USA DOM instead).
- Chromoly pivot tubes, rod ends, or steering ends depending on the kit.
- Lifetime warranty language on the fabricated arms for the plus-forward arms, 3" kits, 5" kits, 8" kit, and complete package (read each page for coverage).
- TIG welded construction called out on several of those listings.
The HD11 complete kit goes heavier: 1.75" OD arms with 1/4" wall DOM, front arms shifted 3" forward, rear arms raked 3" backward for a longer wheelbase, and clearance up to 40" tires.
Wheelbase and tire size in practical terms
Moving the front tires forward changes how much rubber fits in the well. Owners feel that as room for tire diameter and, on some kits, a more planted front end. The HD11 listing is the most explicit about rear geometry too: raking the rear arms backward lengthens the wheelbase. Exact “feels like X inches” numbers are not printed as a single figure on every page, so treat the tire clearance claims on each product page as the source of truth (35", 37", 40", or 46" with portals where stated).
If you only need a small height bump for a nearly stock tire, a spacer kit may be enough. If you want real mud or trail tires—and adjustable camber/caster—forward arms are the CATVOS answer on Defender.
